	Much efficiency depends upon the ship's crew. Speed depends also upon setting sail, trimming lines and getting the vessel properly underway. In stronger winds, however, a ship may lose speed despite the greater force available, as the crew must reduce sail to keep the vessel under control. Canvas that would drive the ship swiftly in fair weather becomes dangerous in a gale, threatening to tear rigging loose, carry away spars or press the hull too hard against the sea. The crew's effort turns from gaining speed to preserving the ship, keeping enough sail set to maintain steerage while preventing the vessel from being overpowered or driven toward foundering.

-'''Wind effects of movement''' describes the adjustment of a sailing vessel's movement according to its [[Ship's Attitude|attitude]] in relation to the wind. This relationship explains how a ship, as it turns with respect to the wind, gains or loses speed even while the [[Wind Force|wind force]] remains unchanged. Speed adjusts because the sails do not receive the wind equally from every angle; some attitudes fill the canvas efficiently, while others strike or pass across the sails with little effect, or pushes against the vesselin a way that actively slows it's progress.

 __TOC__
 The '''ship's attitude''' is its orientation of a vessel in relation to the wind, divided into reaching, running, close-hauling and heading into the wind. This attitude determines how efficiently the sails use the wind, from the high speed of reaching to the complete loss of forward movement when the ship points into the wind.

@@ Line 59: / Line 59: @@
 Note that this occurs above wind force 7, when movement penalties begin to accrue due to the violence of the wind and difficulties related to the ship's handling; these penalties derive differently from those caused by a lack of wind. Where a negative is indicated, the ship should be considered essentially at the mercy of the wind while in that attitude, being driven across the water regardless of its orientation.
-Because yare ships are lighter and more responsive, they gain more from a useful wind, but suffer more when the wind becomes too violent to master. In hard weather, the same quickness that lets such a vessel leap forward under good sail may cause it to be shoved, twisted or driven aside when the sails can no longer be made to serve the crew. A heavier, duller ship answers more slowly, but may also resist the wind’s abuse longer, simply because there is more weight and stubbornness in her hull.

 This quality reflects the ship's design rather than the crew's skill alone. A broad, heavy or awkward vessel may be difficult to bring into a useful attitude, even with a competent crew, while a lighter and better-balanced ship may respond readily. Thus, yare affects how well the ship converts wind into movement once its attitude to the wind has changed.
-To determine the effect of wind force on a ship, cross-index the present wind force with the ship's yare, using the column for the ship’s current attitude to the wind. The number found is the ship’s total movement allowance, expressed in ship or combat hexes, and is used to determine how many actions the vessel may plot during the movement notation phase. A positive result indicates controlled movement under sail. A result of zero indicates that the ship cannot make headway in that attitude. Where the result is less than zero, the ship is no longer moving under effective control; the negative number gives the number of hexes the vessel drifts with the wind, regardless of its orientation.

 The [[Wind_Force#Wind_Effects_on_Ship_Handling|wind effects on ship handling table]] shows how increased wind force affects the ease with which a ship can be managed. The number of ship or combat hexes per round on that table describes the ship's best speed while reaching, which drives the ship more efficiently than running. Running does not permit every sail upon the ship to fill, as the sails upon the stern mast, at the back of the ship, can block the wind from reaching the sails forward. When the ship is reaching, however, every sail can make its fullest use of the wind.
-In stronger winds, speeds fall because the crew must reduce sail and fight to keep the vessel from being overpowered or foundering.

-In addition to the quality of a ship's crew, ship types are also rated according to "yare" — the vessel's natural readiness and responsiveness under sail. A yare ship answers the helm quickly, takes advantage of changes in wind more easily and adjusts its attitude with less loss of movement. As the wind shifts, or as the ship turns from reaching to running or close-hauling, a yare vessel is better able to keep its sails usefully filled and preserve its speed.
