ISO 12217-3:2013 download free.Small craft — Stability and buoyancy assessment and categorization — Part 3: Boats of hull length less than 6 m.
This part & Iso 12217 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of craft vulnerable to swamping are also encompassed.
The evaluation of stebubty and buoyency properties using this pert of ISO 12217 will enable the boat to be assigned to a design category (CorD) appropriate to its design and maximum load.
This part of ISO 12217 Is applicable to boats of hull length less than 6 m whether propeled by human or mechanical power, except habitable sailing multlhuls. Boats of huM length less than 6 m which are fitted with a full deck and quick-draining cockpit(s) complying with ISO 11812 may alternatively be assessed using ISO 12217-1 or ISO 12217-2 (for non-sailing and sailing boats, respectively), In which case higher design categories may be assigned.
In relation to habitable multihulls. this part of ISO 12217 Includes assessment of vulnerability to Inversion. definition of viable means of escape and requirements for Inverted flotation.
This part of ISO 12217 excludes:
— rflatable and riØd-lnflatable boats covered by ISO 5185, except for references made In ISO 6185 to specific clauses of ISO 12217;
— personal watercraft covered by Iso 13590 and other similar powered craft;
— aquatic toys;
— canoes and kayaks;
— gondolas and pedalos;
— saihng surf boards;
— surfboards. Including powered surfboards;
— hydrofoils. foil stabilized boats and hovercraft when not operating in the displacement mode and
— submersibles.
NOTE Displacement mode means that tie boel only supported by hy&ostatic forces.
It does not Include or evaluate the effects on stability of towing, fishing. dredging or lifting operations, which need to be separately considered If appropriate.
light craft condition
empty craft oondtion plus standard equipment (3.4.10) plue removable ballast (whether aced or liquid) when supplied and/or witended by the manufadi.,er to be caned when the boat is afloat, with elements positioned as follows:
a) where provision is made for propulsion by outboard engine(s) of more than 3 kW. the heaviest engine(s) recommended for the boat by the manufacturer, mounted in the working poshon(s)
b) where batteries are fitted, they are mounted In the posibon intended by the budder, and if there is no specIfic stowage provided for batteries, the mass 01 one battery for each engine over 7 kW is allowed for. end located within 1.0 m of the engine location:
C) all upwind sails suppled or recommended by the budder as standard. onboard and ngged ready for use, but not hoisted. e.g mainsail on boom, roller furling sails furled. hanked foresails on stay slowed on foredeck
NOTE 1 For the minimum mass of outboard engines and battens;, refer 10 Taaies Ci and C.2. NOTE 2 The mess In the light o’alt condilion Is denoted by “LC sid Is expressed In kuloams.
maximum load
greatest load which the boat is designed to carry in addition to the light craft condition, comprising:
— the crew limit at 75 kg each (adult) or 37,5 kg (child):
— the personal effects of the crew
— stores and cargo (if any), dry provisions, consumable liguidsc
— contents of all permanently installed storage tanks filled to 95 % of their maximum capsoity. induding fuel. drinking water, black water, grey water, lubricating and hydraLdic oil, bail tanks and/or live wells plus ballast water at 100 % capacity:
— consumable liquids in portable tanks (drinking water, fuel) filled to 95 % of the maximum capacity:
— dinghy or other small craft intended to be carried aboard, and any outboard motor associated with them;
— liferaft(s) If carried in excess of the rtanimum required in essential safety equipment
— non-edible stores and equipment normally carried on the boat and not included lithe manufacturer’s list of standard equipment. e.g. loose internal equipment and tools, spare parts. additional anchors or satls. dinghy and outboard ii carried aboard:
— an allowance for the maximum mass of optional equipment and fittings not included di the manufacturer’s basic outfit
NOTE I tjlerafts are not mctuded in essential safety equismeni lot Categories C and 0.
NOTE 2 As a guide, not less than 20 kgPeraon should be allowed for personal effects on haixtable boats
NOTE 3 As a guide, the mass of yachting liferalts varies from apcroicimately 124 2CL (kg) to double the, according to spec4lcation.
NOTE 4 The mass ot maximum load is denoted by and Is expressed In kilograms.
maxImum load condItion
boat in the light craft condition with the maximum load added so as to produce the design trim
NOTE The mass en the maximum load condition is denoted by .,vioc and is expressed In kdograms If a sailing boat can also be used as a non-sailing boat. e.g. with oars or engine, it shall also generally be assessed as a non-sailing boat, see also 7.1. The design category finally given Is that for which the boat satisfies all the relevant requirements. See Annex 0.
NOTE 1 Boats may be given different ew limits andor design categories according to whether they are being used as sailing or non-sailing bols,
NOTE 2 AttentiOn Is drawn to optIon 3 to Table 3, which may be apprognate we same cas.s.
53.1.3 If a sailing boat also used as a non-sailing boat has been assessed using options 7.8 or9 of Table 7. if
LI Is unable to pass any non-sail test then the boat is deemed to be acceptable if the safety sign given en Figure 8
le displayed In a prominent position. When this sign is fitted, it shall comply with Clause 8.
5.4 Alternatives
If the boat does not reach the desired design category, modify the maximum load andix the number of crew and repeat the assessment.
Boats which are fully enclosed may alternatively be assessed using ISO 12217-1 or ISO 12217-2. for non- sailing and sailing boats respectively. In which case they may be able to attain design category A or B.
5.5 Variation In input parameters
Users of this part of ISO 12217 shait consider the effect on compliance of vanabons In the empty craft mass within the builder’s manufacturing tolerances.
6 Tests to be applied to non-sailing boats
6.1 General
Non-sailing boats may be assessed by any one of six options according to length of hull, amount of flotation and decking, and whether the boat is fitted with suitable recesses complying with ISO 11512. These options and the corresponding tests to be applied are given in Table 3.
NOTE For any given test, the requirements may vary accordmg to the chosen option. e.g. for doenflooding heagit
The design category finally given in respect of stability arid buoyancy is that for Which the boat satisfies all the relevant requirements.
Fully enclosed boats may alternatively be assessed using ISO 12217-1. in which case higher design categories may be assigned.
Where boats are fitted with a bow loading ramp then either the bow ramp must be watertight to degree 2 (see 3.4.11) or the boat must comply with this part of ISO 12217 when the bow ramp is open.
6.2 Habitable non-sailing multihull boats
6.2.1 Habitable non-sailing multihull boats, if considered to be vulnerable to Inversion when used In their design category, in addition to Clause 6 shall also comply with:
a) the requirements for Inverted buoyancy given in ISO 12217-22013. 7.12, and b) the requirements for escape after inversion given en ISO 12217-22013. 7.13. NOTE A habitable boat is del’med to 3.1.7.
