SHEAVE: The ‘wheel’ inside a pulley block or set into a spar to lead a rope or turn it’s direction of pull.
SHEET: The rope which controls the set of a sail.
SHEET BEND: A knot used to join two ropes.
Sheave
A wheel used to change the direction of a line, such as in a block or at the top of the masthead.
Sheer
1) The fore and aft curvature of the deck. 2) A sudden change of course.
sheave - A pulley wheel over which riggings wires or sheets are run, used to change the direction of force.
SHEAVE-The wheel in a block or at the masthead.

SHOAL-Shallow.
Sheave -- The grooved wheel in a block or in the sheave hole of a spar over which the rope passes.
Sheet -- The rope by which the clew of a sail is secured.
Snotter -- An eye strop used to support the heel of a sprit.
sheave: wheel inside a block over which a rope runs the grooved wheel in a block, or in a masthead fitting or elsewhere, over which a rope runs - pronounced "shiv." sheer: the line of the upper deck when viewed from the side.
Has a roller or sheave, which turns on a pin between two metal or plastic cheeks.
Bolt rope
Rope attached to the luff and foot of the mainsail so that the sail can be fed into the mast or boom.
BLOCK The name given to a pulley or sheave, or a system of pulleys or sheaves, mounted in a frame or shell and used for moving objects by means of ropes run over the pulleys or sheaves. The prefixes, single, double, triple, etc.
Choke the Luff - To temporarily stop all movement of a line through a block by placing the hauling part across the sheave of the block. This jams the sheave and holds it tight, and a pull on the hauling part will release it.

" BLOCK A wood, metal, or synthetic casing containing one or more pulleys or sheaves. BIMINI Sun shade. A bimini provides protection from the sun. It is commonly made from fabric mounted on a collapsable frame.

Ropes, if tight laid, will not easily bend round small sheaves, but will take up a considerable part of the power to force them into their proper direction; hence it follows, that blocks with small pins, large sheaves, and slack-laid ropes, ...
DAVIT - A curved piece of timber or iron with a roller or sheave at the end, projecting from the ship's bow, and used to fish the anchor.
BLOCK A wood or metal pulley with sheaves or wheels through which the ropes are rove. BOAT A fairly indefinite term. A waterborne vehicle smaller than a ship. One definition is a small craft carried aboard a ship.
Sheave - The wheel of a block pulley.
Sheet - A rope or chain which regulates the angle of adjustment of a sail in relation in relation to the wind. Usually attached to the lower corner of a sail, or to a yard or a boom.
A single block has one sheave, a double block two sheaves, and so on. A becket block has a fixed eye as well as one or more sheaves. A bullet block is very small. A cheek block is always open on one side. A turning block redirects a line.
In general the more sheaves in the blocks that make up a tackle, the higher its mechanical advantage. The matter is slightly complicated by the fact that every tackle has a working end where the final run of rope leaves the last sheave.
The best location for use of the cutting tool is near the reel spool behind the idler sheave. This allows the cut to be made in a confined space and gives the best chance to complete the cut with the cable in motion.
Block: An assemblage of one or more sheaves (pulley) housed in a plastic or metal case that changes the direction of travel of a line (rope), and may be attached to a yacht's deck, spar or other stationary object.
A pulley - a nautical term. Often with more than one wheel (sheave being the proper name) to increase its mechanical advantage.
Boom
A spar (a wooden or metal pole) attached to the mast at a right angle, used to support the foot of a sail.
A wooden, metal or plastic case in which one or more sheaves (pulleys) are placed, through which turns of line (falls) are threaded for the purpose of gaining mechanical advantage or changing the direction of motion.
To increase the mechanical power of the ropes used in hauling heavy loads. Parts of the Block: Shell, sheave, and pin.
Bobstay
{N/A}
Line from stem to cutwater securing bowsprit.
This console is a wedge-shaped molding that allows the steering cable to run fair while eliminating one set of idler sheaves. Jib tracks run along the edge of the house and the side decks are clear except for the chainplates.
Sheave: The wheel of a block pulley.
Shroud: A line or wire running from the top of the mast to the spreaders, then attaching to the side of the vessel.
Jammed halyard between the block's sheave and cheeks.
#14. Oversized bimini ( canvas tent to block sun and rain over the cockpit ), which prevented the lowering of the boom to obtain the correct level for proper shape of the mainsail.
