Variable-pitch propeller (marine)

<h2 id="sail-boats">Sail boats</h2>
<p>A <a href="/facts/Sailboat/1dygt5l1">sailboat</a> or <a href="/facts/Motorsailer/P1t4N9rk">motorsailer</a> when voyaging on sail alone will benefit from reduced drag, and just like an aeronautical propeller, a marine VPP may be "feathered" to give the least water resistance when sailing without using power. A VPP is particularly useful when motorsailing (i.e. voyaging under both power and sail), as the VPP can be coarsened to incorporate the wind component. If the prop remained at the "normal" setting, it would be too fine and the engine would provide little useful contribution; but by coarsening the prop, the engine provides useful thrust, resulting in a higher speed yet reduced fuel consumption because of the sailing component resistance.
