This part of ISO 12217 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.<\/p>\n
The evaluation of stability and buoyancy properties using this part of ISO 12217 will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum load.<\/p>\n
This part of ISO 12217 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.<\/p>\n
In relation to habitable multihulls, this part of ISO 12217 includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation.<\/p>\n
This part of ISO 12217 excludes:<\/p>\n
inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to specific clauses of ISO 12217;<\/p>\n<\/li>\n
gondolas and pedalos;;<\/p>\n<\/li>\n
surfboards including sailing surfboards; and;<\/p>\n<\/li>\n
hydrofoils and foil stabilized boats when not operating in the displacement mode.;<\/p>\n<\/li>\n<\/ul>\n
\nNOTE Displacement mode means that the boat is only supported by hydrostatic forces.<\/p>\n<\/blockquote>\n
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.<\/p>\n
