Sponson Platform projecting outboard from the hull.


Spreaders The struts used to spread the shrouds to a wider staying angle.


Spring line A shore line led forward from the stern or aft from the bow either to stop the boat surging fore-and-aft, or to assist in manoeuvring.

Stanchion Stainless steel or bronze rods providing support for the guardrails at the deck edge.


Standing rigging The wire rigging which supports the mast.


Starboard The right-hand side of the boat looking forward.


Staysail A sail set on a stay. Used especially in boats with more than one headsail, or more than one mast. In common parlance for modern yachts, the staysail is generally the inner headsail of a cutter.

Tackle Pronounced ‘taykul’, although in the form ‘block and tackle’ it is ‘tackul’. An arrangement of pulley blocks and rope used to gain mechanical advantage. Typical application is a mainsheet. Ground tackle (pronounced ‘tackul’) is the name given to anchors and their associated cables.


Taffrail The section of toerail or bulwark capping running athwart the stern.


Terminals


Standing rig: A proprietary fitting worked into the end of a wire rope by which a shroud or stay can be attached to the mast or the ship.


Electrical: A fitting crimped or soldered to the end of an electrical wire to make a connection.


Tide-rode A boat moored or anchored in a tidal stream will head up to either the wind or the tide, whichever is stronger. If she opts for the tide, she is tide-rode.
