sailing Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ''ice'' (iceboat) or on ''land'' (land yacht) over a chosen cou ...

, hiking (stacking or stacking out in New Zealand; leaning out or sitting out in United Kingdom) is the action of moving the crew's body weight as far to windward (upwind) as possible, in order to decrease the extent the boat heels (leans away from the wind). By moving the crew's weight to windward, the moment of that force around the boat's center of buoyancy is increased. This opposes the heeling movement of the wind pushing sideways against the boat's sails. It is usually done by leaning over the edge of the boat as it heels. Some boats are fitted with equipment such as hiking straps (or toe straps) and trapezes to make hiking more effective. Hiking is most integral to catamaran and

s means that it is rare to capsize them due to wind alone, but keelboat racers will still hike to prevent unnecessary heeling, or leaning sideways to leeward, because the more vertical in the water the keel is, the more effective it is at keeping the boat moving in a forward direction and preventing it from drifting to leeward, slowing the boat due to drag, and potentially increasing the distance the boat must sail when beating. Improper heel creates a tendency for the boat to turn off course, necessitating a correction with the rudder, which also increases drag. Sails use wind most efficiently when they are at a proper heel, another reason for controlling heel.

Hiking equipment
