How Does a Trysail Work?

A trysail (also known as a "spencer") is a small triangular or square fore-and-aft rigged sail hoisted in place of a larger sail when winds are very high. The trysail provides enough thrust to maintain control of the ship (e.g. to avoid ship damage, and to keep the bow to the wind).

How does a storm sail work?

Storm Tactics

Sail under storm jib and deeply reefed mainsail or storm trysail. This approach provides the most control. Sails give you the power to steer and control your boat in the waves. Run before the storm with the stern toward the waves, perhaps towing a drogue to slow the boat.
