<p>ISO 12217-1:2013 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 12217-1:2013 will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum total load.</p>
<p>ISO 12217-1:2013 is principally applicable to boats propelled by human or mechanical power of 6 m up to 24 m hull length. However, it can also be applied to boats of under 6 m 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 12217-1:2013 includes assessment of vulnerability to inversion, definition of viable means of escape and requirements for inverted flotation.</p>
<p>ISO 12217-1:2013 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>personal watercraft covered by ISO 13590 and other similar powered craft;</li>
<li>gondolas and pedalos;</li>
<li>sailing surfboards;</li>
<li>surfboards, including powered surfboards;</li>
<li>hydrofoils and hovercraft when not operating in the displacement mode (displacement mode means that the boat is only supported by hydrostatic forces); and</li>
<li>submersibles.</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>
