The main advantage of this design is the fact that it distributes the weight or the center of gravity of the water vessel. Early Austronesians discovered that round logs tied together into a raft were more stable than a single log. Multi-Hull. [19], Some multihulls with four (quadrimaran) or five (pentamaran) hulls have been proposed; few have been built. This is particularly noticeable when running the wind; a monohull will roll incessantly, while a catamaran will remain upright. However, unlike a monohull, a multihull has a "point of no return" which will lead to the vessel becoming inverted.

The design concept consists of a bow with little buoyancy, a hull that slopes inward from the waterline and, ergo, a large reduction in wave-making resistance. Ideal for these Multi-Hull boats vary in length from 23ft to 90ft and can carry 1 to 74 passengers. During this time we’ve enjoyed working with many prominent designers and naval architects to produce a wide selection of one-off craft, each with their own specific … Having no ballast, multihulls that become holed or inverted have a high rate of survivability; water-tight bulkheads should prevent sinking if the hulls fail.
