Head – The head is the upper edge of the sail, and is attached at the throat and peak to a gaff, yard, or sprit. [7] For a triangular sail the head refers to the topmost corner. Leech – The aft (back) edge of a fore-and-aft sail is called the leech (also spelled leach). [8] The leech is either side edge of a symmetrical sail—triangular or ...
Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull , with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.
[6] [9] On a given sail, the net aerodynamic force on the sail is located approximately at the maximum draught intersecting the camber of the sail and passing through a plane intersecting the centre of effort, normal to the leading edge (luff), roughly perpendicular to the chord of the sail (a straight line between the leading edge (luff) and ...
Reconstruction of a 19th-century naval architect's office, Aberdeen Maritime Museum General Course of Study leading to Naval Architecture degree Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation ...
Edges – The top of all sails is called the head, the leading edge is called the luff on fore-and-aft sails [37] and on windward leech symmetrical sails, the trailing edge is the leech, and the bottom edge is the foot. The head is attached at the throat and peak to a gaff, yard, or sprit. [38] For a triangular sail the head refers to the ...
A large pure cruising boat would be likely to have solar panels, wind generated electricity, multiple heads (bathrooms), a complete galley (kitchen), comfortable cabins and even laundry facilities. Many cruiser designs are cutter rigged meaning they carry two headsails, and many have a second mast , in the yawl or ketch configuration. Having ...
In the architecture of a ship, a companion or companionway is a raised and windowed hatchway in the ship's deck, with a ladder leading below and the hooded entrance-hatch to the main cabins. [1] A companionway may be secured by doors or, commonly in sailboats , hatch boards which fit in grooves in the companionway frame.
Julian Bethwaite was the first to rig and sail a boat with one the next season, followed shortly by Andrew Buckland. The first modern offshore sailboats to incorporate a retractable bow sprit and an asymmetric spinnaker was the J/Boats J/105. [9] The concept has spread rapidly through the sailing world.
