Higher speeds compared to equivalent power from diesels.

High speed catamaran hull design. Instinctively you might think that fine ends would be faster as they would cut through the water better. A discussion about catamaran hull shapes and how they relate to performance and sea keeping with specific reference to the 33 catamaran Mad Max. Height of sailplan CE.

To get speed the hull shape is flatter with he shallow vee absorbing less power but still adequate to cushion the ride. Variable draft means you can navigate in shallow waters too. When planing a monohull will exceed its hull speed.

This is the latest generation of the seacat 20 metre high speed catamaran hull and represents the best in high performance fuel efficient hulls. In order to avoid pounding the semi-circular section should be distorted into a rounded vee or parabolic section. The hull design of these cats has been partly responsible for the very high speeds and these cats use asymmetric hulls with vertical sides in the tunnel and a vee on the outside.

The basic form is one of a fine entry bow and a flat box like stern section with 850mm maximum demi-hull beam giving a length to beam ratio of 12351 for our 11m hull. Modern design and faired exteriors allows for a glossy blue paint job. This innovative SWATH design is based on four interconnected variable draft torpedo like hulls which increase hydrodynamic and seakeeping performance for greater speeds and superior comfort.

QUAD TM 4-Hull High-Speed SWATH. But in fact you want a high Cp for high speeds. Effects of design parameters such as deadrise angle cross-section shape length-to-beam ratio forefoot contour etc.

Giving 50hp per ton with a top speed of around 23 knots. A high speed high efficiency stable catamaran boat hull which comprises a boat hull structure having an under surface a curved bow and a generally flat stern a pair of spaced-apart sponsons on either side of the keel line of the hull and extending generally substantially from the bow of the hull wherein the sponsons generally come to a point to the stern of the hull. Half overall beam half hull beam racing cat Stars and Stripes had a 161 HFR.
