As ship design evolved from craft to science, designers learned various ways to produce long curves on a flat surface. Generating and drawing such curves became a part of ship lofting; "lofting" means drawing full-sized patterns, so-called because it was often done in large, lightly constructed mezzanines or lofts above the factory floor.
Use of computer-aided design has superseded paper-based methods of ship design that relied on manual calculations and lines drawing. Since the early 1990s, a variety of commercial and freeware software packages specialized for naval architecture have been developed that provide 3D drafting capabilities combined with calculation modules for ...
Drua, also known as na drua, n'drua, ndrua or waqa tabu ("sacred canoe", Fijian pronunciation: [waᵑɡa taᵐbu]), is a double-hull sailing boat that originated in the south-western Pacific islands. Druas do not tack but rather shunt (stern becomes the bow and vice versa).
Rothman contacted Uniflite, a Bellingham, Washington boat builder, and by 1974 the first Valiant rolled off their line. The design combined the classic canoe stern cruiser shape with a fin keel and skeg hung rudder instead of the traditional full keel. [4] These two starts led to more design commissions for Islander Yachts and Tayana Yachts.
A sail plan is a drawing of a sailing craft, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. [1] By extension, "sail plan" describes the arrangement of sails on a craft. [2] [3] A sailing craft may be waterborne (a ship or boat), an iceboat, or a sail-powered land vehicle.
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 ...
The F50 is a one-design foiling catamaran used in the SailGP race series. The name is an abbreviation of "Foiling" and "a hull length of 50 feet". [1]The F50s are adapted from the AC50s used in the America's Cup, with modifications including new control systems and modular wingsails. [2]
The design of the boat is what is known as a Bermuda sloop, or a Marconi sloop, being single-masted and Bermuda rigged. The result may be considered a reminder of yachting's "Golden age" with the traditional metre-boat's long overhangs, graceful sheer, deep, narrow hull, and lofty rig. An IOD sloop and a 19th-century Bermudian working boat in ...
