SCHEDULE I (ss. 2, 3, 26, 40, 46 and 51) REGULATIONS FOR DETERMINING FREEBOARDS Part I General 1. (1) On every ship the cargo and ballast shall be stowed in such a manner as to ensure that the ship is sufficiently stable and is not subjected to excessive structural stress. (2) The Administration shall satisfy itself that the general structural strength of the hull of every ship is sufficient for the draught corresponding to the freeboard assigned. Ships built and maintained in conformity with the requirements of a classification society recognized by the Administration may be considered to possess adequate strength. Application 2. (1) Subject to subsections (5) and (6), ships with mechanical means of propulsion or lighters, barges or other ships without independent means of propulsion, shall be assigned freeboards in accordance with the provisions of Regulations 1-40 inclusive. (2) Ships carrying timber deck cargoes may be assigned, in addition to the freeboards prescribed in paragraph (1) of this Regulation, timber freeboards in accordance with the provisions of Regulations 41-45 inclusive. (3) Ships designed to carry sail, whether as the sole means of propulsion or as a supplementary means, and tugs, shall be assigned freeboards in accordance with the provisions of Regulations 1-40 inclusive. Such additional freeboard shall be required as determined by the Administration. (4) Ships of wood or composite construction, or of other materials the use of which the Administration has approved, or ships whose constructional features are such as to render the application of this Schedule unreasonable or impracticable, shall be assigned freeboards as determined by the Administration. (5) Regulations 10-26 inclusive shall apply to every ship to which a minimum freeboard is assigned. Relaxations from these requirements may be granted to a ship to which a greater than minimum freeboard is assigned on condition that the Administration is satisfied with the safety conditions provided. (6) The Board may assign to any dredger, sandsucker, open hopper barge or other ship of special design a freeboard that is less than the freeboard calculated in accordance with Part III of this schedule, or partly or wholly exempt such a ship from the provisions of Regulation 14, if the ship (a) is engaged in voyages that are not international voyages; (b) meets the requirements for the issue of a Local Load Line Certificate; and (c) is of such design and stability that such lesser freeboard or such exemption, as the case may be, will not adversely affect its safety. Definitions of Terms used in the Schedules 3. (1) Length. The length (L) shall be taken as 96 per cent of the total length on a water line at 85 per cent of the least moulded 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 water line, if that is greater. In ships designed with a rake of keel the water line on which this length is measured shall be parallel to the designed water line. (2) 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 water line on which the length is measured. (3) Amidships. Amidships is at the middle of the length (L). (4) Breadth. Unless expressly provided otherwise, the breadth (B) is the maximum breadth of the ship, measured amidships to the moulded line of the frame in a ship with a metal shell and to the outer surface of the hull in a ship with a shell of any other material. (5) Moulded Depth. (a) The moulded 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 ships 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. (b) In ships having rounded gunwales, the moulded depth shall be measured to the point of intersection of the moulded lines of the deck and sides, the lines extending as though the gunwale were of angular design. (c) Where the freeboard deck is stepped and the raised part of the deck extends over the point at which the moulded depth is to be determined, the moulded 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. (6) Depth for Freeboard (D). (a) The depth for freeboard (D) is the moulded depth amidships, plus the thickness of the freeboard deck stringer plate, where fitted, plus 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 (9)(d). (b) The depth for freeboard (D) in a ship having a rounded gunwale with a radius greater than four per cent of the breadth (B) or having topsides of unusual form is the depth for freeboard of a ship 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. (7) Block Coefficient. The block coefficient (Cb) is given by: r is the volume of the moulded displacement of the ship, excluding bossing, in a ship with a metal shell, and is the volume of displacement to the outer surface of the hull in a ship with a shell of any other material, both taken at a moulded draught of d1; and where d1 is 85 per cent of the least moulded depth. (8) Freeboard Deck. 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 ship are fitted with permanent means of watertight closing. In a ship having a discontinuous 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 Administration, 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. 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. (9) Superstructure. (a) A superstructure is a decked structure on the freeboard deck, extending from side to side of the ship or with the side plating not being inboard of the shell plating more than four per cent of the breadth (B). A raised quarter deck is regarded as a superstructure. (b) 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 Regulation 12, (iii) all other openings in sides or ends of the superstructure fitted with efficient weathertight means of closing. 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 these superstructures by alternative means which are available at all times when bulkhead openings are closed. (c) 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. (d) The length of a superstructure (S) is the mean length of the part of the superstructure which lies within the length (L). (10) Flush Deck Ship. A flush deck ship is one which has no superstructure on the freeboard deck. (11) Weathertight. Weathertight means that in any sea conditions water will not penetrate into the ship. Deck Line 4. The deck line is a horizontal line 300 mm in length and 23 mm in breadth. It shall be marked amidships on each side of the ship, and its upper edge shall normally pass through the point where the continuation outwards of the upper surface of the freeboard deck intersects the outer surface of the shell (as illustrated in Figure 1), provided that the deck line may be placed with reference to another fixed point on the ship on condition that the freeboard is correspondingly corrected. The location of the reference point and the identification of the freeboard deck shall in all cases be indicated on the International Load Line Certificate (1966). Load Line Mark 5. The Load Line Mark shall consist of a ring 300 mm in outside diameter and 25 mm wide which is intersected by a horizontal line 450 mm in length and 25 mm in breadth, the upper edge of which passes through the centre of the ring. The centre of the ring shall be placed amidships and at a distance equal to the assigned summer freeboard measured vertically below the upper edge of the deck line (as illustrated in Figure 2). Lines to be used with the Load Line Mark 6. (1) The lines which indicate the load line assigned in accordance with these Regulations shall be horizontal lines 230 mm in length and 25 mm in breadth which extend forward of, unless expressly provided otherwise, and at right angles to, a vertical line 25 mm in breadth marked at a distance 540 mm forward of the centre of the ring (as illustrated in Figure 2). (2) The following load lines shall be used: (a) the Summer Load Line indicated by the upper edge of the line which passes through the centre of the ring and also by a line marked S; (b) the Winter Load Line indicated by the upper edge of a line marked W; (c) the Winter North Atlantic Load Line indicated by the upper edge of a line marked WNA; (d) the Tropical Load Line indicated by the upper edge of a line marked T; (e) the Fresh Water Load Line in summer indicated by the upper edge of a line marked F. The Fresh Water Load Line in summer is marked abaft the vertical line. The difference between the Fresh Water Load Line in summer and the Summer Load Line is the allowance to be made for loading in fresh water at the other load lines; and (f) the Tropical Fresh Water Load Line indicated by the upper edge of a line marked TF, and marked abaft the vertical line. (3) If timber freeboards are assigned in accordance with these Regulations, the timber load lines shall be marked in addition to ordinary load lines. These lines shall be horizontal lines 230 mm in length and 25 mm in breadth which extend abaft unless expressly provided otherwise, and are at right angles to, a vertical line 25 mm in breadth marked at a distance 540 mm abaft the centre of the ring (as illustrated in Figure 3). (4) The following timber load lines shall be used: (a) the Summer Timber Load Line indicated by the upper edge of a line marked LS; (b) the Winter Timber Load Line indicated by the upper edge of a line marked LW; (c) the Winter North Atlantic Timber Load Line indicated by the upper edge of a line marked LWNA; (d) the Tropical Timber Load Line indicated by the upper edge of a line marked LT; (e) the Fresh Water Timber Load Line in summer indicated by the upper edge of a line marked LF and marked forward of the vertical line. The difference between the Fresh Water Timber Load Line in summer and the Summer Timber Load Line is the allowance to be made for loading in fresh water at the other timber load lines; and (f) the Tropical Fresh Water Timber Load Line indicated by the upper edge of a line marked LTF and marked forward of the vertical line. (5) Where the characteristics of a ship or the nature of the ship's service or navigational limits make any of the seasonal lines inapplicable, these lines may be omitted. (6) Where a ship is assigned a greater than minimum freeboard so that the load line is marked at a position corresponding to, or lower than, the lowest seasonal load line assigned at minimum freeboard in accordance with the present Convention, only the Fresh Water Load Line need be marked. (7) On sailing ships only the Fresh Water Load Line and the Winter North Atlantic Load Line need be marked (as illustrated in Figure 4). (8) Where a Winter North Atlantic Load Line is identical with the Winter Load Line corresponding to the same vertical line, this load line shall be marked W. (9) Additional load lines required by other international conventions in force may be marked at right angles to and abaft the vertical line specified in subsection (1) of this Regulation. Mark of Assigning Authority 7. The mark of the Authority by whom the load lines are assigned may be indicated alongside the load line ring above the horizontal line which passes through the centre of the ring, or above and below it. This mark shall consist of not more than four initials to identify the Authority's name, each measuring approximately 115 mm in height and 75 mm in width. Details of Marking 8. The ring, lines and letters shall be painted in white or yellow on a dark ground or in black on a light ground. They shall also be permanently marked on the sides of the ships to the satisfaction of the Administration. The marks shall be plainly visible and, if necessary, special arrangements shall be made for this purpose. Verification of Marks 9. The International Load Line Certificate (1966) shall not be delivered to the ship until the officer or surveyor acting under the provisions of Article 13 of the present Convention has certified that the marks are correctly and permanently indicated on the ship's sides. Part II Conditions of Assignment of Freeboard Information to be supplied to the Master 10. (1) The master of every new ship shall be supplied with sufficient information, in an approved form, to enable him to arrange for the loading and ballasting of his ship in such a way as to avoid the creation of any unacceptable stresses in the ship's structure, provided that this requirement need not apply to any particular length, design or class of ship where the Administration considers it to be unnecessary. (2) The master of every new ship which is not already provided with stability information under an international convention for the safety of life at sea in force shall be supplied with sufficient information in an approved form to give him guidance as to the stability of the ship under varying conditions of service, and a copy shall be furnished to the Administration.
