The evaluation of stability and buoyancy properties using ISO 12217-3:2015 will enable the boat to be assigned to a design category (C or D) appropriate to its design and maximum load.
ISO 12217-3:2015 is applicable to boats of hull length less than 6 m, whether propelled by human or mechanical power, except habitable sailing multihulls. Boats of hull 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, ISO 12217-3:2015 includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation.
ISO 12217-3:2015 excludes:
inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to specific clauses of ISO 12217;
personal watercraft covered by ISO 13590 and other similar powered craft;
canoes and kayaks;
gondolas and pedalos;
surfboards, including powered surfboards;
hydrofoils, foil stabilized boats and hovercraft when not operating in the displacement mode; and
NOTE Displacement mode means that the boat is only supported by hydrostatic forces.
ISO 12217-3:2015 does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.
