<p>This part of ISO 12217 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 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 total load.</p>
<p>This part of ISO 12217 is principally applicable to boats propelled by human or mechanical power of 6 m up to and including 24 m hull length. However, it may 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>This part of ISO 12217 excludes</p>
<ul><li>inflatable and rigid-inflatable boats up to 8 m covered by ISO 6185,</li><li>canoes, kayaks or other boats with a beam of less than 1,1 m,</li><li>hydrofoils and hovercraft when operating in the dynamically supported mode, 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 should be separately considered if appropriate.</p>
