A powered or manual machine used to heave, veer and control an anchor rode. A chain gypsy engages calibrated chain, while a warping drum handles rope and a combined unit may manage a rope-chain rode. Windlasses may have horizontal or vertical shafts and use electric, hydraulic or manual power with a clutch and brake. The…
A vessel used principally for recreation, cruising or sport rather than commercial carriage or working service. A yacht may be sailing or motor-powered and can range from a small cabin craft to a very large vessel. The word describes use and social or regulatory context more than one hull form, size or level of luxury….
A spar set across a mast to support and spread a square sail or another transverse sail arrangement. A square sail’s head is bent or attached along the yard, whose braces rotate it horizontally and whose lifts and halyards support or raise it according to the rig. Yards may be fixed, lowered, hoisted or sent…
Lightweight streamers used to show local airflow over a sail or wind direction around a vessel. Pairs placed on each side of a headsail luff indicate attached or disturbed flow and help adjust sheet trim and steering. Leech telltales show flow leaving a sail, while shroud or masthead telltales can indicate local apparent wind but…
A lever attached to the rudder head or steering system and moved to control the rudder. On a simple arrangement, pushing the tiller to port turns the rudder so that the vessel’s bow turns to starboard when moving ahead, and vice versa. Some vessels use linkages or auxiliary tillers, so the exact movement should be…
A low raised strip or structural edge along a deck margin that helps retain feet and loose objects aboard. A toe rail may be timber, metal or moulded into the hull-to-deck joint and can include drainage gaps or perforations. On some vessels it also carries fittings or contributes to edge stiffness, but those functions depend…
A line or wire supporting or controlling the height of a boom, yard or pole. A mainsail topping lift supports the boom when the sail and halyard do not and may be eased once the sail carries the load. A spinnaker-pole topping lift controls the pole’s vertical position together with a foreguy or downhaul; the…
The exterior sides of a vessel’s hull above the waterline. Topsides extend from the waterline region towards the sheer or deck edge and may include plating, planking or moulded laminate, coatings, rubbing strakes, ports and fittings. The term usually excludes the deck and superstructure. The actual waterline changes with loading, heel and waves, so part…
The structural surface or framing forming the after end of a hull. A transom is commonly flat or slightly curved and may be vertical, raked or stepped. It can carry an outboard engine, rudder fittings, boarding platform, drains, exhausts or other equipment when designed and reinforced for those loads. Not every vessel has a transom;…
A movable car, ring or fitting that changes the position from which a sheet or control applies its load. A mainsheet traveller commonly runs across a track to alter the boom’s lateral position while retaining chosen sheet tension. Travellers are also used on headsail tracks, horse arrangements and other rigging systems, with adjustment by tackles,…
