ISO 12217-2:2015 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of boats susceptible to swamping are also encompassed.
The evaluation of stability and buoyancy properties using ISO 12217-2:2015 will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum load.
ISO 12217-2:2015 is principally applicable to boats propelled primarily by sail (even if fitted with an auxiliary engine) of 6 m up to and including 24 m hull length. However, it can also be applied to boats less than 6 m if they are habitable multihulls or may be applied if they do not attain the desired design category specified in ISO 12217‑3 and they are decked and have quick-draining recesses which comply with ISO 11812.
In relation to habitable multihulls, ISO 12217-2:2015 includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation.
ISO 12217-2:2015 excludes:
inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to specific clauses of ISO 12217;
gondolas and pedalos;
surfboards including sailing surfboards; and
hydrofoils and foil stabilized boats when not operating in the displacement mode.
ISO 12217-2:2015 does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.
