List of sailing boat types - Wikipedia Oct 20, �� Sailboats also use composites in their sail construction, with carbon-fiber or glass-fiber tape offering a flexible but dimensionally stable matrix to which synthetic sailcloth is laminated. Carbon fiber has other marine uses too � for example for high-strength interior moldings and furniture on super-yachts. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more. Formula. SA/D = SA ? (D ? 64) 2/3. SA: Sail area in square feet, derived by adding the mainsail area to % of the foretriangle area (the lateral area above the deck between the mast and the forestay). D: Displacement in pounds. Mar 27, �� Many boats are designed with a �shoe-box� joint where the hull and deck have mating flanges, or overlap one another. Often mechanical fasteners such as screws or through-bolts are used to secure the parts together, in addition to the use of a chemical bonding agent and sealant like methyl methacrylate or 3M , which also makes the joint water-tight.

Soon, glass-reinforced plastic became mainstream and GRP boats started to become available in the early s. Wartime pressures also led to the development of cold-molded and hot-molded boatbuilding techniques.

These approaches entailed laying thin veneers of wood over a frame and saturating each layer with a glue. High-performance urea-based adhesives developed for aircraft manufacturers were widely used for the new technique of molding boat hulls � typically for PT boats.

Some adhesives required baking in an oven to cure and hot-molded hulls were developed, though there were size limitations governed by access to industrial ovens. Since the s, polyester and vinylester resins have improved steadily and GRP has become the most prevalent composite used in boatbuilding.

It is used in shipbuilding too, typically for minesweepers that need non-magnetic hulls. Osmotic problems from which early-generation boats suffered are now a thing of the past with modern epoxy compounds. In the 21 st century, volume GRP boat production follows a full industrial production process.

Strip planking is one such popular technique for home boat construction: Strips of wood typically cedar are laid longitudinally over frames and coated with epoxy. This simple construction offers a cheap and strong build with a fair finish easily achievable by an amateur. At the leading edge of boat building, aramid fiber reinforcing strengthens key areas of sailboats, such as the bows and keel sections.

Aramid fiber also provides improved shock absorption. Displacement kg. Ballast kg. Waterline Length m. Length Overall m. Beam m. D : Displacement in pounds. LWL: Waterline length in feet. Capsize Screening Formula This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions.

Hull Speed The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. Classic formula: 8.
