Trysail
Small sail for high winds / From Wikipedia, the free encyclopedia
For the Japanese music group, see TrySail.
A trysail (also known as a spencer[citation needed]) is a small triangular or gaff rigged sail hoisted in place of a larger mainsail when winds are very high.[1] 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. It is hoisted abaft (i.e., directly behind) the mainmast (taking the place of the much larger mainsail) or, on a brig, abaft the foremast.[2] A trysail is analogous to a storm jib.
