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.
The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. The earliest evidence of maritime transport by modern humans is the settlement of Australia between 50,000 and 60,000 years ago. This almost certainly involved rafts, possibly equipped with some sort of sail.
A carvel boat has a smoother surface which gives the impression that it is more hydrodynamically efficient since the exposed edges of the clinker planking appear to disturb the streamline and cause drag. A clinker certainly has a slightly larger wetted area, but a carvel hull is not necessarily more efficient: for given hull strength, the ...
Ancient boat building methods can be categorized as one of hide, log, sewn, lashed-plank, clinker (and reverse-clinker), shell-first, and frame-first. While the frame-first technique dominates the modern ship construction industry, the ancients relied primarily on the other techniques to build their watercraft. In many cases, these techniques ...
VB-10,000 is a heavy-lift twin-gantry catamaran consisting of two truss space frames atop two barges.The design was derived from Versabar's earlier VB-4000 (aka Bottom Feeder), [1] [2] which was developed to clear debris from toppled oil drilling platforms in the Gulf of Mexico.
The Sailfish sailboat is a small, hollow body, board-boat style sailing dinghy. The design is a shallow draft , sit-upon hull carrying a lateen rigged sail mounted to an un- stayed mast . This style sailboat is sometimes referred to as a "wet boat" because, with its minimal freeboard , the sailor often gets splashed by spray as the boat moves ...

It was designed by Jay Kantola, and built by Richard and Kris Barrie of California. In 2010 it was converted by Philip Maise to an aft-mast rig with a self-tacking crab-claw sail. Video in External Links Warick Collins, experimental boat builder, and inventor of both the tandem keel and the universal hull, now uses an aft-mast rig.
