It is difficult to get much over 067 without a very distorted hull shape or one with excessive WSA.

Best catamaran hull design. The Catana 59 was fitted with these curved daggerboards that look like foils. As it was previously mentioned the most stable boat hull is the flat hull design. In practice the most stable hull design depends on the specific conditions in which the boat will be used.

3 Not so efficient semi-displacement hull. These catamarans arent built for performance but on a trade wind route with 20-25 knots of true wind on the stern the Lagoon 42 will do 7 to 8 knots in comfort. The most famous representative of this category is the catamaran.

Twin 50hp outboards will cruise this catamaran at 17 knots using 1 litermile or 38 miles gallon with top speed of 21 knots thanks to a fineness ratio of 15 to 1. However the key to Catamaran design is you need a higher Cp if you want to sail fast. So all multihulls should have a Cp between 061 and 065.

With different situations the most stable hull winner changes. The hull and deck are in high. The first catamaran I ever sailed an ocean passage on was a Shuttleworth 44.

The noisy and sometimes disconcerting slamming takes getting used to. It seemed like a good idea at the time. Built in Florida and beloved by the owners of the over 120 boats built during the companys existence from 1993 to 2009 the Manta Catamarans range included 38- 40- and 44-foot cats.

Their cat designs resemble. Perhaps the best example of a properly designed planing power catamaran is the Arrowcat designed by Roger Hill. ALL catamarans slam waves hitting under the bridge deck.
