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.
A comparison of clinker and carvel construction. Carvel frames are much heavier than clinker ribs.. Carvel built or carvel planking is a method of boat building in which hull planks are laid edge to edge and fastened to a robust frame, thereby forming a smooth surface.
[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 ...
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 ...
Chine log construction is a method of building hard-chine boat hulls. Hard chines are common in plywood hulls, while soft chines are often found on fiberglass hulls. Traditional planked hulls in most cultures are built by placing wooden planks oriented parallel to the waterflow and attached to bent wooden frames.
