TRY, TO, OR LIE-TO, IN A GALE, is, by a judicious balance of canvas, to
keep a ship's bow to the sea, and, with as much as she can safely show,
prevent her rolling to windward in the trough of a sea. Close-hauled
under all sail, a vessel gains head-way within six points of the wind;
but in _trying_ she may come up to five and fall off to seven: so that a
vessel does not hold her own. If the vessel be in proper trim, or
properly stowed, she will naturally keep to the wind; but custom, and
deficiency of seamanlike ability, have induced the lazy habit of lashing
the helm a-lee.

TRY BACK FOR A BEND, TO. To pay back some of the bight of a cable, in
order to have sufficient to form the bend.

TRY DOWN, TO. To boil out the oil from blubber at sea in whalers.

TUB, MATCH. A conical tub used to guard the slow match in action. They
were formerly about five-gallon capacity, the head being sunk about two
inches, and four holes bored to insert slow matches. They are now almost
disused, except to keep a light ready for signal purposes, as rockets,
blue lights, &c., by night.
