Small craft - Stability and buoyancy assessment and categorization - Part 3: Boats of hull length less than 6 m (ISO 12217-3:2015); German version EN ISO 12217-3:2015

2Scope / Description

This part of ISO 12217 specifies the procedures for assessing the stability and buoyancy of intact (i.e., undamaged) vessels. It also includes the buoyancy characteristics of vessels susceptible to being overfilled. Assessing stability and buoyancy characteristics according to this part of ISO 12217 allows for the assignment of a vessel to a design category (Category C or Category D) appropriate to its design and maximum load. This part of ISO 12217 applies to hulls less than 6 meters in length, powered by human or motor, but excludes habitable multihull sailing vessels. Fully enclosed vessels less than 6 meters in length equipped with fast-draining hatches as required by ISO 11812 may alternatively be assessed according to ISO 12217-1 (for non-sailing vessels) or ISO 12217-2 (for sailing vessels), potentially allowing for assignment to a higher design category. Regarding habitable multihull vessels, this part of ISO 12217 includes assessments of capsizing tendency, definitions of effective escape routes, and requirements for buoyancy in a capsized state (keel up). This part of ISO 12217 does not apply to the following: inflatable boats and rigid inflatable boats (RIBs) according to ISO 6185, except where specific sections of ISO 12217 are referenced in this standard; motorboats and other similarly powered water vehicles according to ISO 13590; water toys; canoes and kayaks; rowboats and pedal boats; surfboards; surfboards (including motor surfboards); ground effect boats (powered and wind-driven) and hovercraft, unless operating in displacement mode; and submersibles.
