NF EN ISO 12217-3

<p>ISO 12217-2:2013 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of boats vulnerable to swamping are also encompassed.</p> <p>The evaluation of stability and buoyancy properties using ISO 12217-2:2013 will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum load.</p> <p>ISO 12217-2:2013 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> <p>In relation to habitable multihulls, ISO 12217-2:2013 includes assessment of vulnerability to inversion, definition of viable means of escape and requirements for inverted flotation.</p> <p>ISO 12217-2:2013 excludes:</p> <ul> <li>inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to specific clauses of ISO 12217;</li> <li>gondolas and pedalos;</li> <li>surfboards including sailing surfboards; and</li> <li>hydrofoils and foil stabilized boats when not operating in the displacement mode (displacement mode means that the boat is only supported by hydrostatic forces).</li> </ul> <p>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>

<p>ISO 12217-3:2015 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of craft susceptible to swamping are also encompassed.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>ISO 12217-3:2015 excludes:</p> <p> inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to specific clauses of ISO 12217;</p> <p> personal watercraft covered by ISO 13590 and other similar powered craft;</p> <p> aquatic toys;</p> <p> canoes and kayaks;</p> <p> gondolas and pedalos;</p> <p> sailing surfboards;</p> <p> surfboards, including powered surfboards;</p> <p> hydrofoils, foil stabilized boats and hovercraft when not operating in the displacement mode; and</p> <p> submersibles.</p> <p>NOTE Displacement mode means that the boat is only supported by hydrostatic forces.</p> <p>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.</p>
