Such recommendation and authorization will depend upon provision of any additional features as deemed necessary by the authorities to ensure the vessel's safety in the services and under the conditions specified in paragraph (b) of this section. (b) Exemptions from specific load line requirements for vessels meeting requirements of paragraph (a) of this section are authorized, subject to certain conditions, including type of voyage engaged in, as follows: (1) For vessels engaged on international voyages between the United States and near neighboring ports of its possessions or of foreign countries. The exemptions may be permitted because the requirements are deemed to be unreasonable or impracticable due to the sheltered nature of the waters on which the voyages occur or other conditions. These exemptions shall be valid only so long as such a vessel shall remain engaged on specific designated voyages. If the voyage involves a foreign country or countries, the United States will require an exemption agreement with such country or countries prior to the issuance of the appropriate load line certificate. (2) For vessels engaged on international voyages which embody features of a novel kind, and where nonexemption may seriously impede research, development, and incorporation of novel features into vessels. If the voyage or voyages intended involve a foreign country or countries, then the United States will require an exemption agreement with such country or countries prior to the issuance of a Load Line Exemption Certificate. If the Commandant grants an exemption pursuant to this paragraph (b)(2) to a U.S. flag vessel that operates on the Great Lakes of North America, he may notify the Chairman of the Board of Steamship Inspection of Canada of the nature of the exemption, but no special exemption certificate is issued. (3) For a vessel not normally engaged on international voyages but which is required to undertake a single international voyage under exceptional circumstances. (4) For self-propelled hopper dredges engaged on international voyages or on limited service domestic voyages by sea. These vessels may be exempt from applicable hatch cover requirements of §42.15–25 of this part by showing they meet the requirements in §174.310 of this chapter. When a Load Line Exemption Certificate is issued for this exemption, it must have an endorsement that only seawater is allowed in the vessel's hoppers. (c) A vessel given one or more exemptions from load line requirements under the provisions of paragraph (b)(1) of this section will be issued the appropriate load line certificate, using Form A1, A2, or A3. In each case the exemptions shall be specified on the load line certificate together with the Convention authority which authorizes such exemptions. (d) A vessel given one or more exemptions under the provisions of paragraph (b)(2) or (b)(3) of this section will be issued a Load Line Exemption Certificate, using Form E1. This certificate shall be in lieu of a regular load line certificate, and the vessel shall be considered as in compliance with applicable load line requirements. (e) The Commandant may exempt from any of the requirements of this part a vessel that engages on a domestic voyage by sea or a voyage solely on the Great Lakes and embodies features of a novel kind, if the novel features and any additional safety measures required are described on the face of the issued certificate. (f) A vessel that is not usually engaged on domestic voyages by sea or on voyages on the Great Lakes but that, in exceptional circumstances, is required to undertake a single such voyage between two specific ports is— (1) Subject to 46 U.S.C. 5101–5116 and the applicable regulations of this subchapter; and (2) Issued a single voyage load line authorization by the Commandant that states the conditions under which the voyage may be made and any additional safety measures required for a single voyage.

It was agreed to exempt vessels of the United States and Canadian vessels from load line requirements when such vessels engage on international voyages originating on, wholly confined to, and terminating on such waters. In Article I of this Treaty these waters are described as follows: “* * * the waters of Puget Sound, the waters lying between Vancouver Island and the mainland, and east of a line from a point 1 nautical mile west of the city limits of Port Angeles in the State of Washington to Race Rocks on Vancouver Island, and of a line from Hope Island, British Columbia, to Cape Calvert, Calvert Island, British Columbia, the waters east of a line from Cape Calvert to Duke Point on Duke Island, and the waters north of Duke Island and east of Prince of Wales Island, Baranof Island, and Chicagof Island, the waters of Peril, Neva, and Olga Straits to Sitka, and the waters east of a line from Port Althorp of Chicagof Island to Cape Spencer, Alaska, are sheltered waters * * *.” (b) U.S.-flag vessels and Canadian vessels navigating on the treaty waters on a voyage as described in paragraph (a) of this section are by virtue of this Treaty of August 11, 1934, not subject to load line requirements in 46 U.S.C. 5101–5116, the 1966 Convention, and the regulations in this subchapter. Vessels navigating these sheltered waters and passing outside their boundary on any voyage cannot claim the benefits of this Treaty and shall be in compliance with the applicable load line requirements in 46 U.S.C. 5101–5116, the 1966 Convention, and the regulations in this subchapter. (c) Since subdivision requirements apply to all passenger vessels subject to the 1960 International Convention on Safety of Life at Sea, those passenger vessels navigating on the waters described in paragraph (a) of this section shall be in compliance with such 1960 Convention requirements and the regulations in part 46 of this subchapter. The Coast Guard issues to such a vessel a stability letter. The assigning authority is authorized to issue to such a passenger vessel an appropriate load line certificate, modified to meet the conditions governing her service assignment, and marking.

Such action may occur prior to the expiration date on the certificate and normal certificate surrender. The cancellation of such certificate means that the correctness of load line marks and compliance with conditions of assignment for the named vessel no longer are recognized by the United States and that the existing assigned load line marks are voided. (b) Certain causes for automatic cancellation of certificates are: (1) The conditions of assignment have not been maintained as required by this subchapter. (2) Material alterations have taken place in the hull or superstructure of the vessel, which will necessitate the assignment of an increased freeboard. (3) The fittings and appliances have not been maintained in an effective condition for the protection of openings, guardrails, freeing ports, and means of access to crew's quarters. (4) The structural strength of the vessel is lowered to such an extent that the vessel is unsafe. (5) The load line certificate or International Load Line Exemption Certificate is not endorsed to show the vessel has been surveyed annually or periodically by the issuing authority as required by this part or the 1966 Convention. (6) Issuance of a new load line certificate for the same vessel. (7) Surrender of a certificate for cancellation when required. (8) The owner, master, or agent of the vessel has furnished false or fraudulent information in or with the application for a certificate.

The Coast Guard District Commander may detain a vessel if it is so loaded as to be manifestly unsafe to proceed to sea. (b) If the District Director of Customs orders a vessel detained, he shall immediately inform the Coast Guard District Commander thereof, who shall thereupon advise the District Director of Customs whether or not he deems that the vessel may proceed to sea with safety. If the Coast Guard District Commander orders a vessel detained, such officer will furnish the District Director of Customs immediate notification of such detention. The clearance shall be refused to any vessel which shall have been ordered detained, which shall be in effect until it is shown that the vessel is not in violation of the applicable law and the regulations in this subchapter. (1) Where a vessel is detained for noncompliance with “material alteration” and “effective maintenance” requirements of paragraph (f)(1) of this section, the detention shall only be exercised insofar as may be necessary to ensure that the vessel can proceed to sea without danger to passengers or crew. (c) The detention of a vessel will be by written order of either the Coast Guard District Commander or the District Director of Customs, depending on who orders the detention. The Coast Guard District Commander will immediately arrange for a survey in the manner prescribed by 46 U.S.C. 5113. Unless the owner or agent waives in writing and stipulates to accept the Coast Guard's survey, the Coast Guard District Commander shall appoint three disinterested surveyors and, where practicable, one of them shall be from the Surveying Staff of the American Bureau of Shipping. Such surveyors shall conduct a survey to ascertain whether or not the vessel is loaded in violation of the applicable provisions in the load line acts, and the regulations in this subchapter. If the survey confirms the allegation that the vessel is in violation of either law or the applicable regulations in this subchapter, “the owner and agent shall bear the costs of the survey in addition to any penalty or fine imposed”, as provided in these laws. (d) Whenever a vessel is detained, the master or owner may, within 5 days, appeal to the Commandant who may, if he desires, order a further survey, and may affirm, set aside, or modify the order of the detaining officer. (e) Where a foreign vessel is detained or intervention action of any other kind is taken against a foreign vessel, the officer carrying out the action shall immediately inform in writing the Consul or the diplomatic representative of the State whose flag the vessel is flying, of the decision involved together with all pertinent circumstances under which intervention was deemed necessary. (f) Under 46 U.S.C. 5109 a vessel of a foreign country which has ratified the 1966 Convention, or which holds a recognized and valid 1930 Convention certificate, or which holds a valid Great Lakes Certificate, shall be exempt from the provisions of the regulations in this subchapter insofar as the marking of the load lines and the certificating thereof are concerned, so long as such country similarly recognizes the load lines established by this subchapter for the purpose of a voyage by sea subject to the proviso in paragraph (f)(1) of this section or the alternative proviso in paragraph (f)(2) of this section. (1) If the foreign vessel is marked with load lines and has on board a valid International or Great Lakes Load Line Certificate certifying to the correctness of the marks, the control provisions in this part which are in accord with Article 21 of the 1966 Convention shall be observed. In this connection, the vessel shall not be loaded beyond the limits allowed by the certificate. The position of the load lines on the vessel shall correspond with the certificate. The vessel shall not have been so materially altered as to make the vessel manifestly unfit to proceed to sea without danger to human life, in regard to: (i) The hull or superstructure (if necessitating assignment of an increased freeboard); and/or, (ii) The appliances and fittings for protection of openings, guardrails, freeing ports, and means of access to crew's quarters (if necessitating replacement or other effective maintenance). (2) (Alternatively provided) If the foreign vessel has on board an International Load Line Exemption Certificate in lieu of an International Load Line Certificate, 1966, in such case, verify that it is valid and any conditions stipulated therein are met. (g) A foreign vessel of a nation for which the 1966 Convention has not come into force does not qualify for an International Load Line Certificate, 1966. In lieu thereof, such a vessel shall be required to have on board a valid Form B load line certificate or a recognized 1930 Convention certificate.

Certain vessels, such as vessels carrying all their cargo as deck cargo, or vessels where design or service require special conditions to be applicable, shall have certain stability limitations imposed on them, as may be necessary. When stability limitations for a vessel are prescribed, the assigning authority shall furnish the master the vessel's maximum draft permitted and other conditions, including reference to Commandant approved operating stability features, which may be applicable. (1) No load line assignment shall be made under this part to a vessel proceeding on a foreign voyage, or where the load line assignment is related to the flooded stability provisions and the vessel is proceeding on a domestic voyage, until the applicable light ship characteristics are established and incorporated into the vessel's stability data approved by the Commandant and furnished to the master of the vessel. (2) If load line assignments are made to vessels for coastwise voyages before the results of the required stability characteristics are determined and incorporated into the vessel's stability data approved by the Commandant, then such load line assignments shall be regarded as conditional and shall be subject to verification or modification for removal of the conditional status. Any vessel with a conditional load line assignment shall not be loaded beyond a conservative safe draft. Where the Commandant deems it unnecessary, the requirement for furnishing stability information to the masters of coastwise vessels assigned load lines not related to flooded stability may be omitted and the assigning authority and others concerned will be so notified. (b) Each vessel subject to load line requirements shall carry on board a valid certificate attesting to compliance with such requirements. (See §§42.07–35 and 42.07–40 for additional data furnished to the vessel.) (c) The master of the vessel for which a load line certificate has been issued shall be responsible for the maintenance of such certificate on board such vessel and for compliance with its terms and conditions. Additionally, the master shall be responsible for having the current load line survey report on board the vessel. This report shall be made available to surveyors when carrying out subsequent load line surveys.

Before issuing a certificate or placement of load line marks on a vessel, the assigning and issuing authority shall make an initial or periodic survey of the vessel as required by this subchapter. A load line survey report shall be made, reflecting information and facts based on initial surveys, including required and special elements as may be deemed necessary by the assigning authority or the Commandant. (b) Initial survey. An initial survey shall be made before the vessel is put in service or the first time the assigning authority is requested to survey a vessel. The survey shall include a complete examination of its structure and equipment insofar as required by the applicable requirements in this subchapter. This survey shall be such as to ensure that the arrangements, materials, scantlings, and subsequent placement of load line marks fully comply with applicable requirements. (c) Periodical survey. A periodical survey shall be made at intervals not exceeding five (5) years from an initial or previous periodic survey. The survey shall be similar to the initial survey insofar as extent and purpose are concerned. (1) If the load line marks are found to be correct for the condition the vessel is then in, the assigning and issuing authority shall issue a new load line certificate, valid for such time as the condition of the vessel then warrants but in no case for a period of longer than 5 years. If, after a survey has been passed, a loadline certificate can not be issued before the current certificate expires, the current certificate may be extended by an endorsement in accordance with the requirements contained in §42.07–45(d). This endorsement of the assigning authority shall be placed on the back of the certificate, as shown on the forms in subpart 42.50. However, if there have been alterations which affect the vessel's freeboards, such extension shall not be granted. This prohibition is the same as in Article 19(2) of the 1966 Convention. (2) The periodical survey, including certificate extension or reissue, for a vessel holding an international load line exemption certificate for more than one voyage, shall be the same as for any other vessel covered by this section except for load line marks. However, other conditions specified in the exemption certificate shall be verified. (d) Annual surveys for endorsements. Vessels subject to initial and periodic surveys shall have annual surveys, within 3 months either way of the certificate's anniversary date. The annual surveys shall be made by and prove satisfactory to the assigning and issuing authority prior to executing the required annual endorsements on load line certificates or exemption certificates. The scope shall be as defined in §42.09–40 and such as to ensure that the applicable load line marks are found to be correct for the condition the vessel is then in.

The length (L) shall be taken as 96 percent of the total length on a waterline at 85 percent of the least molded depth measured from the top of the keel, or as the length from the foreside of the stem to the axis of the rudder stock on that waterline, if that be greater. In vessels designed with a rake of keel the waterline on which this length is measured shall be parallel to the designed waterline. (b) Perpendiculars. The forward and after perpendiculars shall be taken at the forward and after ends of the length (L). The forward perpendicular shall coincide with the foreside of the stem on the waterline on which the length is measured. (c) Amidships. Amidships is at the middle of the length (L). (d) Breadth. Unless expressly provided otherwise, the breadth (B) is the maximum breadth of the vessel, measured amidships to the molded line of the frame in a vessel with a metal shell and to the outer surface of the hull in a vessel with a shell of any other material. (e) Molded depth. (1) The molded depth is the vertical distance measured from the top of the keel to the top of the freeboard deck beam at side. In wood and composite vessels the distance is measured from the lower edge of the keel rabbet. Where the form at the lower part of the midship section is of a hollow character, or where thick garboards are fitted, the distance is measured from the point where the line of the flat of the bottom continued inwards cuts the side of the keel. (2) In vessels having rounded gunwales, the molded depth shall be measured to the point of intersection of the molded lines of the deck and sides, the lines extending as though the gunwale were of angular design. (3) Where the freeboard deck is stepped and the raised part of the deck extends over the point at which the molded depth is to be determined, the molded depth shall be measured to a line of reference extending from the lower part of the deck along a line parallel with the raised part. (f) Depth for freeboard (D). (1) The depth for freeboard (D) is the molded depth amidships, plus the thickness of the freeboard deck stringer plate, where fitted, plus T(L-S)/L if the exposed freeboard deck is sheathed; where: T is the mean thickness of the exposed sheathing clear of deck openings; and S is the total length of superstructures as defined in paragraph (j)(4) of this section. (2) The depth for freeboard (D) in a vessel having a rounded gunwale with a radius greater than 4 percent of the breadth (B) or having topsides of unusual form is the depth for freeboard of a vessel having a midship section with vertical topsides and with the same round of beam and area of topside section equal to that provided by the actual midship section. (g) Block coefficient. The block coefficient (Cb) is given by Cb=?/L.B.d1 where ? is the volume of the molded displacement of the vessel, excluding bossing, in a vessel with a metal shell, and is the volume of displacement to the outer surface of the hull in a vessel with a shell of any other material, both taken at a molded draft of d1; and, d1 is 85 percent of the least molded depth. (h) Freeboard. The freeboard assigned is the distance measured vertically downward amidships from the upper edge of the deck line to the upper edge of the related load line. (i) Freeboard deck. (1) The freeboard deck is normally the uppermost complete deck exposed to weather and sea, which has permanent means of closing all openings in the weather part thereof, and below which all openings in the sides of the vessel are fitted with permanent means of watertight closing. In a vessel having a discontinuance freeboard deck, the lowest line of the exposed deck and the continuation of that line parallel to the upper part of the deck is taken as the freeboard deck. At the option of the owner and subject to the approval of the assigning authority a lower deck may be designated as the freeboard deck, provided it is a complete and permanent deck continuous in a fore and aft direction at least between the machinery space and peak bulkheads and continuous athwartships. When this lower deck is stepped the lowest line of the deck and the continuation of that line parallel to the upper part of the deck is taken as the freeboard deck. (2) When a lower deck is designated as the freeboard deck, that part of the hull which extends above the freeboard deck is treated as a superstructure so far as concerns the application of the conditions of assignment and the calculation of freeboard. It is from this deck that the freeboard is calculated. (j) Superstructure. (1) A superstructure is a decked structure on the freeboard deck, extending from side to side of the vessel or with the side plating not being inboard of the shell plating more than 4 percent to the breadth. (B). A raised quarter deck is regarded as a superstructure. (2) An enclosed superstructure is a superstructure with: (i) Enclosing bulkheads of efficient construction; (ii) Access openings, if any in these bulkheads fitted with doors complying with the requirements of §42.15–10; and, (iii) All other openings in sides or ends of the superstructure fitted with efficient weathertight means of closing. Note: A bridge or poop shall not be regarded as enclosed unless access is provided for the crew to reach machinery and other working spaces inside the superstructures by alternative means, which are available at all times when bulkhead openings are closed. (3) The height of a superstructure is the least vertical height measured at side from the top of the superstructure deck beams to the top of the freeboard deck beams. (4) The length of a superstructure (S) is the mean length of the part of the superstructure which lies within the length (L). (k) Flush deck vessel. A flush deck vessel is one which has no superstructure on the freeboard deck. (l) Weathertight. Weathertight means that in any sea conditions water will not penetrate into the vessel.

[CGD 79–153, 48 FR 38648, Aug. 25, 1983] § 42.20-9 Initial conditions of loading. top When doing the calculations required in §§42.20–6(a), 42.20–7(a) and 42.20–8(a), the initial condition of loading before flooding must be assumed to be as specified in this section: (a) The vessel is assumed to be loaded to its summer load waterline with no trim. (b) When calculating the vertical center of gravity, the following assumptions apply: (1) The cargo is assumed to be homogeneous. (2) Except as specified in paragraph (b)(3) of this section, all cargo compartments are assumed to be fully loaded. This includes compartments intended to be only partially filled. In the case of liquid cargoes, fully loaded means 98 percent full. (3) If the vessel is intended to operate at its summer load waterline with empty compartments, these empty compartments are assumed to be empty rather than fully loaded if the resulting height of the vertical center of gravity is not less than the height determined in accordance with paragraph (b)(2) of this section. (4) Fifty percent of the total capacity of all tanks and spaces fitted to contain consumable liquids or stores must be assumed to be distributed to accomplish the following: (i) Each tank and space fitted to contain consumable liquids or stores must be assumed either completely empty or completely filled. (ii) The consumables must be distributed so as to produce the greatest possible height above the keel for the center of gravity. (5) Weights are calculated using the following values for specific gravities: Salt water—1.025 Fresh water—1.000 Oil fuel—0.950 Diesel oil—0.900 Lube oil—0.900 [CGD 79–153, 48 FR 38648, Aug. 25, 1983] § 42.20-10 Free surface. top When doing the calculations required in §§42.20–6(a), 42.20–7(a) and 42.20–8(a), the effect of free surface of the following liquids must be included: (a) For each type of consumable liquid, the maximum free surface of at least one transverse pair of tanks or a single centerline tank must be included. The tank or combination of tanks must be that resulting in the greatest free surface effect. (b) For cargo liquids, unless the compartment is assumed to be empty as required by §42.20–9(b)(3), the free surface of those compartments containing liquids is calculated at an angle of heel of not more than 5 degrees. [CGD 79–153, 48 FR 38649, Aug. 25, 1983] § 42.20-11 Extent of damage. top When doing the calculations required by §§42.20–6(a), 42.20–7(a) and 42.20–8(a), the following must be assumed: (a) The vertical extent of damage in all cases must be assumed to be from the baseline upward without limit. (b) The transverse extent of damage is assumed to be equal to B/5 or 11.5 meters (37.7 feet), whichever is less. The transverse extent is measured inboard from the side of the ship perpendicularly to the center line at the level of the summer load waterline. (c) If damage of a lesser extent than that specified in paragraph (a) or (b) of this section results in a more severe condition, the lesser extent must be assumed. (d) The following assumptions apply to the transverse damage specified in paragraph (b) of this section for a stepped or recessed bulkhead: (1) A transverse watertight bulkhead that has a step or recess located within the transverse extent of assumed damage may be considered intact if the step or recess is not more than 3.05 meters (10 feet) in length. (2) If a transverse watertight bulkhead has a step or recess of more than 3.05 meters (10 feet) in length, within the transverse extent of assumed damage, the two compartments adjacent to this bulkhead must be considered as flooded. (3) If within the transverse extent of damage, a transverse bulkhead has a step or recess more than 3.05 meters (10 feet) in length that coincides with the double bottom tank top or the inner boundary of a wing tank, respectively, all adjacent compartments within the transverse extent of assumed damage must be considered to be flooded simultaneously. (e) If a wing tank has openings into adjacent compartments, the wing tank and adjacent compartments must be considered as one compartment. This provision applies even where these openings are fitted with closing appliances except: (1) Valves fitted in bulkheads between tanks which are controlled from above the bulkhead deck. (2) Secured manhole covers fitted with closely spaced bolts. (f) Only transverse watertight bulkheads that are spaced apart at least 1/3(L) 2/3 or 14.5 meters (0.495(L) 2/3 or 47.6 feet), whichever is less, may be considered effective. If transverse bulkheads are closer together, then one or more of these bulkheads must be assumed to be non-existent in order to achieve the minimum spacing between bulkheads. [CGD 79–153, 48 FR 38649, Aug. 25, 1983] § 42.20-12 Conditions of equilibrium. top The following conditions of equilibrium are regarded as satisfactory: (a) Downflooding. The final waterline after flooding, taking into account sinkage, heel, and trim, is below the lower edge of any opening through which progressive flooding can take place. Such openings include air pipes, ventilators, and openings which are closed by means of weathertight doors (even if they comply with §42.15–10) or covers (even if they comply with §42.15–30 or §42.15–45(d)) but may exclude those openings closed by means of: (1) Manhole covers and flush scuttles which comply with §42.15–40; (2) Cargo hatch covers which comply with §42.09–5(b); (3) Hinged watertight doors in an approved position which are secured closed while at sea and so logged; and (4) Remotely operated sliding watertight doors, and side scuttles of the non-opening type which comply with §42.15–65. (b) Progressive flooding. If pipes, ducts, or tunnels are situated within the assumed extent of damage penetration as defined in §42.20–11 (a) and (b), progressive flooding cannot extend to compartments other than those assumed to be floodable in the calculation for each case of damage. (c) Final angle of heel. The angle of heel due to unsymmetrical flooding does not exceed 15 degrees. If no part of the deck is immersed, an angle of heel of up to 17 degrees may be accepted. (d) Metacentric height. The metacentric height of the damaged vessel, in the upright condition, is positive. (e) Residual stability. Through an angle of 20 degrees beyond its position of equilibrium, the vessel must meet the following conditions: (1) The righting arm must be positive. (2) The maximum righting arm must be at least 0.1 meter (4 inches). (3) The area under the righting arm curve within the 20 degree range must not be less than 0.0175 meter-radians (0.689 inch-radians). (4) Each submerged opening must be weathertight (e.g. a vent fitted with a ball check valve). (f) Intermediate stages of flooding. The Commandant is satisfied that the stability is sufficient during intermediate stages of flooding.

(b) A barge that meets the requirements of §42.09–5(b) may be assigned Type “A” freeboard if the barge does not carry deck cargo. (c) An unmanned barge is not required to comply with §42.15–75, §42.15–80(b), or §42.20–70. (d) An unmanned barge that has only small access openings closed by watertight gasketed covers of steel or equivalent material on the freeboard deck, may be assigned a freeboard 25 percent less than that calculated in accordance with this subpart.

(1) The sheer shall be measured from the deck at side to a line of reference drawn parallel to the keel through the sheer line amidships. (2) In vessels designed with a rake of keel, the sheer shall be measured in relation to a reference line drawn parallel to the design load waterline. (3) In flush deck vessels and in vessels with detached superstructures the sheer shall be measured at the freeboard deck. (4) In vessels with topsides of unusual form in which there is a step or break in the topsides, the sheer shall be considered in relation to the equivalent depth amidships. (5) In vessels with a superstructure of standard height which extends over the whole length of the freeboard deck, the sheer shall be measured at the superstructure deck. Where the height exceeds the standard the least difference (Z) between the actual and standard heights shall be added to each end ordinate. Similarly, the intermediate ordinates at distances of 1/6L and 1/3L from each perpendicular shall be increased by 0.444Z and 0.111Z respectively. (6) Where the deck of an enclosed superstructure has at least the same sheer as the exposed freeboard deck, the sheer of the enclosed portion of the freeboard deck shall not be taken into account. (7) Where an enclosed poop or forecastle is of standard height with greater sheer than that of the freeboard deck, or is of more than standard height, an addition to the sheer of the freeboard deck shall be made as provided in paragraph (c)(4) of this section.

L+20................. 1 ---------------------------------------------------------------------------------------------------------------- (c) Measurement of variation from standard sheer profile. (1) Where the sheer profile differs from the standard, the four ordinates of each profile in the forward or after half shall be multiplied by the appropriate factors given in the table of ordinates. The difference between the sums of the respective products and those of the standard divided by 8 measures the deficiency or excess of sheer in the forward or after half. The arithmetical mean of the excess or deficiency in the forward and after halves measures the excess or deficiency of sheer. (2) Where the after half of the sheer has an excess and the forward half of the sheer has a deficiency, no credit shall be allowed for the part in excess and deficiency only shall be measured. (3) Where the forward half of the sheer profile exceeds the standard, and the after portion of the sheer profile is not less than 75 percent of the standard, credit shall be allowed for the part in excess; where the after part is less than 50 percent of the standard, no credit shall be given for the excess sheer forward. Where the after sheer is between 50 percent and 75 percent of the standard, intermediate allowances may be granted for excess sheer forward. (4) Where sheer credit is given for a poop or forecastle, the following formula shall be used: s=(y/3)(L'/L) where: s=sheer credit, to be deducted from the deficiency or added to the excess of sheer. y=difference between actual and standard height of superstructure at the end ordinate. L'=mean enclosed length of poop or forecastle up to a maximum length of 0.5L. L=length of vessel as defined in §42.13–15(a). (i) The formula in this paragraph (c)(4) of this section provides a curve in the form of a parabola tangent to the actual sheer curve at the freeboard deck and intersecting the end ordinate at a point below the superstructure deck a distance equal to the standard height of a superstructure. The superstructure deck shall not be less than standard height above this curve at any point. This curve shall be used in determining the sheer profile for forward and after halves of the vessel. (d) Correction for variations from standard sheer profile. (1) The correction for sheer shall be the deficiency or excess of sheer (see paragraphs (c) (1) to (4) inclusive of this section) multiplied by: 0.75-(S/2L) where: S is the total length of enclosed superstructures. (e) Addition for deficiency in sheer. (1) Where the sheer is less than the standard, the correction for deficiency in sheer (see paragraph (d)(1) of this section) shall be added to the freeboard. (f) Deduction for excess sheer. (1) In vessels where an enclosed superstructure covers 0.1L before and 0.1L abaft amidships, the correction for excess of sheer as calculated under the provisions of paragraph (d)(1) of this section shall be deducted from the freeboard; in vessels where no enclosed superstructure covers amidships, no deduction shall be made from the freeboard; where an enclosed superstructure covers less than 0.1L before and 0.1L abaft amidships, the deduction shall be obtained by linear interpolation. The maximum deduction for excess sheer shall be at the rate of 1 1/2 inches per 100 feet of length.
