SA118/5/P Job Ref No. : STB015‐21/I04 Stability & Buoyancy Assessment – “SA118/5/P” Prelude This booklet is made for the owner. It contains many data and information's provided for the Skipper for his convenience to determine the scheme of loading. Certain loading calculation is necessary before loading in order to keep the vessel with sufficient stability and navigability in every voyage. In the course of loading, the Skipper should be careful about the heel and trim condition of the vessel. In order to prevent the vessel from capsizing, the Skipper should remember to use the equalizing compartment in time to adjust the vessel. As well, cargo should be loaded homogeneously and passengers seating shall comply with seating arrangement. And take measures such as seizing to make the cargo in the hold or some big‐sized equipment to keep good stability. This booklet contains some relative information needed for all kinds of calculations such as the principal data of the vessel, the hydrostatic data, the stability assessment of typical loading conditions, etc. Even if the results of loading calculation shows that it fulfils the requirement of the stability criterion, it's also necessary for the Skipper to pay attention to the climate and the sea condition, and to navigate carefully. Pengenalan Dokumen ini dibuat adalah untuk kegunaan pemilik. Ianya mengandungi data dan maklumat untuk memudahkan Orang Yang Bertanggungjawab dalam menentukan perancangan muatan. Pengiraan muatan tertentu adalah perlu sebelum memulakan proses pemuatan bagi memastikan kestabilan dan pelayaran yang selamat untuk setiap pelayaran. Dalam proses pemuatan, Orang Yang Bertanggungjawab perlu memberi perhatian terhadap keadaan senget dan trim bot. Dalam mengelak bot daripada terbalik, Orang Yang Bertanggungjawab hendaklah menggunakan keseimbangan ruang pada masa yang tepat untuk melaraskan kedudukan bot. Dalam pada itu juga, kargo hendaklah dimuat sama rata dan tempat duduk penumpang hendaklah mematuhi susunatur tempat duduk yang telah ditetapkan. Dan perhatian juga hendaklah diberi dalam ruang kargo atau barangan bersaiz besar dalam mengekalkan kestabilan yang baik. Buku ini mengandung beberapa maklumat relatif yang berkaitan untuk segala pengiraan seperti data utama bot, data hidrostatik, penilaian kestabilan dari keadaan biasa pemuatan dan sebagainya. Walaupun keputusan pengiraan muatan menunjukkan ianya memenuhi keperluan kriteria kestabilan, adalah juga perlu Orang Yang Bertanggungjawab memberi perhatian terhadap cuaca dan keadaan laut, dan mengemudikan secara berhati‐hati. 1
SA118/5/P Job Ref No. : STB015‐21/I04 Stability & Buoyancy Assessment – “SA118/5/P” Instruction to Skipper Notices on Operation This stability information shows that the boat complies with definite stability requirements in designed conditions and gives the data deemed necessary for the calculation and evaluation of stability to the Skipper in order that he can take suitable measures for securing the stability in any service condition. Notes regarding Stability, Loading and General Precautions against Capsizing Compliance with the required minimum stability criteria does not insure immunity against capsizing, regardless of the circumstances, or absolve the Skipper from his responsibilities. Skippers should therefore exercise prudence and good seamanship, have regard to the season of the year, weather forecasts, the navigational zone, and should take appropriate action as to speed and course warranted by the prevailing circumstances. Care should be taken to ensure that cargo, allocated to the boat is capable of being stowed, so that compliance with the stability criteria can be achieved. If necessary, the amount of cargo should be limited to the extent that ballast weight may be required. In determining the sequence of tanks from which fuel oil and fresh water is to be consumed and those into which water ballast may be admitted during the voyage, the Skipper must ensure, prior to departure, that the required minimum stability criteria will be maintained throughout the voyage after making due allowance for free surface effect as may be appropriate. Before a voyage commences, care should be taken to ensure that the cargo and sizeable pieces of equipment have properly stowed or lashed, so as to minimize the possibility of both longitudinal and lateral shifting at sea, under the effect of acceleration caused by rolling and pitching. Skippers should note that stability can be adversely affected by such influences as beam wind on boats with large windage area, movement of passengers, water trapped on deck and in deck compartment, rolling characteristics and following seas. Passenger’s movement and water entrapped in deck compartment will lead to increase weight above deck with resultant loss of stability. Care must therefore be taken to reduce the likelihood of passenger’s movement and allowing water to be trapped in the deck compartment. Access hatches, doors on upper and raised decks are to be secured and closed at all time when the vessel is underway. Trim by the head is to be avoided as this may lead to poor handling qualities when towed. Verified weights and vertical Centre of gravity (VCG) of deck cargo are to be used when assessing the stability. A heel, however caused, should be avoided as this will result in lowering of stability reserves. 2
SA118/5/P Job Ref No. : STB015‐21/I04 Stability & Buoyancy Assessment – “SA118/5/P” Arahan kepada Orang Yang Bertanggungjawab Notis Operasi Maklumat kestabilan ini menunjukkan bot mematuhi keperluan kestabilan tertentu dalam keadaan yang telah ditetapkan dan memberi data yang dianggap perlu untuk rujukan pengiraan dan penilaian kestabilan kepada Orang Yang Bertanggungjawab agar dapat mengambil langkah‐langkah yang bersesuaian bagi memastikan kestabilan yang selamat semasa beroperasi. Notis Berkenaan Dengan Kestabilan, Pemuatan Dan Langkah Berjaga‐Jaga Untuk Mengelak Terbalik Pematuhan terhadap minimum kriteria kestabilan tidak memberi jaminan daripada terbalik, pada sebarang keadaan atau membebaskan Orang Yang Bertanggungjawab daripada tanggungjawab. Oleh itu, Orang Yang Bertanggungjawab hendaklah mempraktikkan ilmu pelayaran yang berhemah, dengan mengambilkira musim sepanjang tahun, ramalan cuaca, zon pelayaran, dan hendaklah mengambil langkah‐langkah yang sewajarnya berkaitan kelajuan dan arah pelayaran bergantung kepada keadaan sebenarnya semasa operasi. Pemantauan hendaklah diberi bagi memastikan kargo yang dimuatkan ke atas bot, dapat mencapai pematuhan kriteria kestabilan. Sekiranya perlu, jumlah berat kargo yang dimuat harus dihadkan sesuai dengan berat ‘ballast’ yang diperlukan. Dalam penentuan urutan pengunaan tangki minyak dan air tawar, dan kemasukan air ‘ballast’ sekiranya berkenaan semasa pelayaran, Orang Yang Bertanggungjawab hendaklah memastikan sebelum memulakan pelayaran, keperluan minimum kriteria kestabilan dikekalkan sepanjang pelayaran. Sebelum memulakan pelayaran, perhatian perlu diberi terhadap kargo dan barangan bersaiz besar dengan memastikan kargo tersebut telah disusun atau diikat sebaiknya, bagi meminimakan kebarangkalian kargo beralih secara ke depan‐belakang dan ke sisi semasa berada di laut, disebabkan oleh kesan olengan dan anggul. Orang Yang Bertanggungjawab hendaklah maklum bahawa kestabilan boleh terjejas oleh pengaruh angin sisi bagi bot yang mempunyai permukaan yang luas pada sebelah tepi, pergerakan penumpang, air terperangkap di atas dek dan dalam petak dek, ciri‐ciri olengan dan pergerakan laut. Pergerakan penumpang dan air yang terperangkap dalam petak dek boleh menyebabkan peningkatan berat di atas dek dan memberi kesan kehilangan kestabilan. Oleh itu, perhatian hendaklah diberi untuk mengurangkan kemungkinan pergerakan penumpang dan air terperangkap di dalam petak dek. Pintu masuk kecil, pintu hendaklah ditutup sepanjang masa semasa pelayaran. Trim bot ke depan hendaklah dielak kerana ini boleh memberi kesan kepada pengendalian yang kurang efektif semasa ditunda. 3
SA118/5/P Job Ref No. : STB015‐21/I04 Stability & Buoyancy Assessment – “SA118/5/P” Berat yang disahkan dan pusat graviti menegak untuk kargo di atas dek perlu diambil perhatian bagi penentuan kestabilan. Kesengetan, yang disebabkan oleh apa‐apa faktor, hendaklah dielak kerana ini boleh menyebabkan pengurangan kestabilan. 4

Ref. Definitions the offset-load test, derived from 6.2.3 and Ta ble 4, and 70 % of the downflooding angle, ϕD, determined using either of the methods of Annex C. 6.5.1 Application This requirement is applicable only to boats of design categories A and B, or those fully enclosed boats of design category C for which the minimum freeboard to the recess coaming does not exceed the required downflooding height of option 6. The boat shall be assessed in the loaded arrival condition. The requirements of 6.5.1 and either 6.5.2 or 6.5.3 shall be applied to all recesses except those a) fitted to boats with an angle of vanishing stability greater than 90°, or b) where the depth of the recess is less than 3 % of the maximum breadth of the recess over at least 35 % of the periphery, or EXAMPLE Toe rails, low bulwarks. c) formed by a bulwark with at least 5 % of its area providing overboard drainage positioned within the lowest 25 % of its height, and where the height of the bulwark is less than 12,5 % of the maximum breadth of the recess, or d) where it can be shown that the unobstructed drainage area from the recess on each side of the boat centreline exceeds K x (the volume of the recess to the recess retention level defined in 3.5.9), where K is: — 0,09 where the drainage openings are within the lowest 25 % of the recess depth; — 0,16 where the drainage openings are within the lowest 50 % of the recess depth; — 0,30 where the drainage openings are the full depth of the recess. To qualify under 6.5.1 c) and d): 1) the lower edge of all drainage openings shall be not more than 10 mm above recess sole height for at least 70 % of the width of each opening, and 2) where drainage area is provided by an open or partially open transom, openings shall extend to the outboard sides of the recess sole on both sides. 6.5.2.1 The percentage loss in initial metacentric height (GMT) due to free-surface effect when the recess is filled to the retention level defined in 3.5.9 and the boat is in the loaded arrival condition shall be not more than: — 250 FR / LH for boats of design category A; — 550 FR / LH for boats of design category B; — 1 200 FR / LH for boats of design category C; where FR is the average freeboard to the waterline of the periphery of the recess FR = (FA + 2FS + FF) / 4 where FA is the average of highest and lowest freeboard to the waterline across aft end of recess; FS is the average of highest and lowest freeboard to the waterline along the sides of recess;
Ref. Definitions FF is the average of highest and lowest freeboard to the waterline across forward end of recess. Compliance with this requirement can be demonstrated by any of the methods given in 6.5.2.2, 6.5.2.3, or 6.5.2.4 for monohulls, or 6.5.2.2 or 6.5.2.3 for multihulls. Alternatively, the direct calculation method of 6.5.3 can be used. 6.5.2.2 The percentage loss in initial metacentric height (GMT) due to freesurface effect can be calculated from: % loss GMT = 102 500 × SMARECESS / MLA x GMT where SMARECESS is the second moment of area of free-surface of recess at retention level as defined in 3.5.9, about the longitudinal axis through the centre of area, expressed in m4 Where multiple recesses have to be considered swamped simultaneously, SMARECESS must include all such recesses. 6.5.2.3 The percentage loss in initial metacentric height (GMT) due to freesurface effect can be estimated from % loss GMT = [ 245 x SMARECESS / SMAWP ] where SMARECESS is the second moment of area of free-surface of recess at retention level as defined in 3.5.9; SMAWP is the second moment of area of waterplane of boat at mLA. Both second moments of area are about the longitudinal axis through the respective centre of area, expressed in m4. Where multiple recesses have to be considered swamped simultaneously, SMARECESS must include all such recesses. 6.5.2.4 The percentage loss in initial metacentric height (GMT) due to freesurface effect can alternatively be estimated more approximately, and therefore more conservatively, from: % loss GMT = 270 [ l x b3 / LH x BH3 ] 0.7 where l is the maximum length of recess at the retention level as defined in 3.5.9; b is the maximum breadth of recess at the retention level as defined in 3.5.9.

B.3.1.7 The “crew area” comprises the “working deck” as defined by the manufacturer in accordance with ISO 15085 plus the areas of all seats, bunks, sunbathing pads, cabin soles and internal decks. It shall include all areas designated to be used by the crew when the boat is stationary, but may exclude ledges less than 0,10 m in width and areas excluded by “no access” signs.

The maximum overall length of the crew area is the simple longitudinal distance between the forward and aft extremities of the crew area. The lengths of different parts should not be added together. B.3.2.3 Calculate the curve of righting moments according to Annex E. B.3.2.4 Calculate the curve of crew heeling moments equal to 961CL(BC/2 − 0,2)cosϕ (N⋅m), where BC is the maximum transverse distance between the outboard extremities of any parts of the crew area as defined in B.3.1.7, and ϕ is the heel angle. Where the crew area includes side decks less than 0,4 m wide, the moment used shall be 480CL BC cosϕ (N⋅m). Ledges less than 0,10 m wide can be excluded from the crew area. B.3.2.5 Plot righting moments and heeling moments on the same graph. The boat satisfies the test if the following are satisfied. — For design category C and D boats (except those complying with the buoyant volume requirements in ISO 6185): at the point of intersection of these curves the minimum freeboard margin before downflooding (see Annex D) is not less than required in Table 5, whether obvious to the crew (e.g. over the gunwale) or not obvious (e.g. through openings in the topsides). — At the point of intersection of these curves, the heel angle (degrees), ϕO, does not exceed 11,5 + ( 24 – LH )3 / 520 see also Table 4. This event shall be ignored for design category D boats that are not fully enclosed.

Fixed tanks shall either be removed, or shall be full with either fuel or water. g) All cockpit and similar drains normally open during operation of the boat shall be left open. The plugs of drains for emptying the boat of residual water when ashore shall be in place. h) Care shall be taken throughout the testing to eliminate entrapped air other than in air tanks or air containers. i) Void compartments integral with the boat structure and not complying with the requirements for air tanks in Annex G shall be opened so that they become swamped with water. j) Boats intended to be fitted with engines of more than 3 kW and which are fitted with integral air tanks that have laminated, glued, welded or bolted seams in their construction, and which air tanks do not comply with the enhanced pressure test of Annex G, shall have a number of air chambers opened to atmosphere during testing, according to Table F.3. F.3.1 A metallic test weight with a dry mass of (6dCL) kg but always more than (15d) kg shall be suspended over the side of the boat at each of four positions in turn. These positions shall be at LH/3 from the ends of the boat (as shown in Figure F.1) or at the ends of the cockpit, if this is nearer amidships. No other test weights shall be in the boat during this test, apart from those required by F.2. F.3.4 With the test weight in each position in turn, swamp the boat by applying a downwards force at a position on the gunwale at approximately mid-LH until the deepest point of the gunwale or coaming is 0,2 m below the water surface. Hold the boat in this position until the water level has equalized between inside and outside, or for 5 min, whichever is less, and then release the boat. F.3.5 For each position of the test weights, after a further 5 min have elapsed, the boat shall not heel more than 45°.
Ref. Definitions F.4 Swamped buoyancy test F.4.3 After a further 5 min have elapsed, the boat shall float approximately level with more than two-thirds of the length of the top of the gunwale or coamings (including those across bow or stern) above water.
