Mitigation
Any action that reduces the angle of heel of a boat that is reaching or beating to windward will help reduce weather helm. Racing sailors use their body weight to bring the boat to a more upright position. Reducing or reefing the total sail area will have the same effect and, counter-intuitively, many boats will sail faster with less sail in a stiff breeze once heel and weather helm have been reduced, due to the reduction in underwater drag (see Over-canvassed sailing). Easing the sheets on aft-most sails, such as the mainsail in a sloop or cutter can have an immediate effect, especially to help with manoeuvering. Moving or increasing sail area forward can also help, for example by raising the jib (and maybe lowering the staysail) on a cutter.
Sailing off the wind, weather helm may be caused by the imbalance due to fore-and-aft sails all being sheeted out on the same (leeward) side of the boat. Raising a spinnaker or poling out a headsail to windward with a whisker pole can help. Yachts making ocean trade wind crossings have rigged 'twins' - double headsails poled out to opposite sides from the same forestay for extended downwind passages without a mainsail. Square rigged sails also provide relatively symmetric drive off the wind.

Famous quotes containing the word mitigation:
“Law is a thing which is insensible, and inexorable, more beneficial and more profitious to the weak than to the strong; it admits of no mitigation nor pardon, once you have overstepped its limits.”
—Titus Livius (Livy)
