This part of ISO 12217 specifies procedures for assessing the stability and buoyancy of intact (ie undamaged) boats. It also records the buoyancy properties of boats that are susceptible to bottoming out. The assessment of stability and buoyancy characteristics according to this part of ISO 12217 allows the boat to be assigned a design category (C or D) corresponding to its design and maximum load. This part of ISO 12217 is applicable to boats with a hull length of less than 6 m that are powered by human power or engines, with the exception of habitable multihull sailboats. Boats with a hull length of less than 6 m, which are fully decked and have fast-draining cockpit(s) according to ISO 11812, can alternatively also be assessed according to ISO 12217-1 or ISO 12217-2 (for non-sailing boats or sailing boats), so that they can be assigned a higher design category if necessary. With regard to habitable multihulls, this part of ISO 12217 includes the assessment of susceptibility to capsizing, definition of viable means of escape and capsized (keel-up) buoyancy requirements. Excluded from the application of this part of ISO 12217 are:
——Inflatable boats and rigid hull inflatable boats (RIBs) conforming to ISO 6185, except for references in that standard to specific clauses in ISO 12217;
——Personal watercraft according to ISO 13590 and other similarly powered watercraft;
——water toys;
——canoes and kayaks;
——Gondolas and pedal boats;
——sailing surfboards;
——Surfboards, including motorized surfboards;
——hydrofoils, powered by motors, sails, and hovercraft, provided they are not operated in displacement mode;
——Submersible vehicles. NOTE Displacement mode means that the boat is supported by hydrostatic forces only. This part of ISO 12217 does not contain information or assessments on the stability effects of towing, fishing, dredging or crane operations; these must be taken into account separately if necessary.
