Trysail

Trisel ( eng. Trysail ) - oblique quadrangular sail , having the form of an irregular trapezoid. The lower trekel is laced to the boom , the upper trek is attached to the hafel , the front one is to the mast (trisel mast) or the sliders sliding on the mast. Trisel harvesting is done with the help of gait gear, which draws the middle of the sail to the mast and hafel. The gitov, which pulls the skipper to the hafel, is called the upper gitov, and the one that pulls the mast to the mast is called the lower. The root gites are mounted in the middle of the rear triselles and held through the block under the heel of the hafel.

Depending on which mast the trisel is located, it is called for-trisel or mainsail.

Trisel is the main sail on the hafel schooners , on which the name is fock , mainsail and mizzen .

On yachts, a trisel is a small- sized storm sail, sewn from durable canvas . Trisel is placed instead of the grotto and raised with the grotto-fal (with Bermuda armament) or a halyard (with a hafel ). The trisel is controlled by the trisellet laid on the clew angle and drawn to the stern of the yacht so that the line of the draft of the clew divides the clew corner of the trisel approximately in half. Trisel on yachts does not have a boom (the boom is fixed or removed from the yoke and placed on the deck) and is lined up on all the crates. Typically, the area of ​​the trisel is not more than 20% of the normal sailing yacht.
