The BN will also tell us about a catamarans ability to withstand stronger winds before reefing.

Most efficient catamaran hull design. Their cat designs resemble their single hull designs. The driving power of any sail-driven craft is the energy of the wind acting through the Center of Effort CE of the sail plan. Based on independent testing the SRD hull with a single engine or twin engines is the most fuel efficient powerboat on the market at speeds over 10 knots12 mph.

Because of design innovations like curved daggerboards and the hydrofoils performance on cruising catamarans has improved tremendously but catamaran speed is relative. Prowler Semi-displacement Prowler VT Vapour Trail Growler Whisper The semi-displacement hull is a slim hull shape with a canoe-end underwater aft meaning this hull simply slides through. However it has extra stabilizing outriggers which enable increased speed.

Trends in Power Catamaran Boat Design. The answer is to decide what the boat is to do then look at the type of hull best suited to the purpose. Solar Navigator has to be capable of cruising in all sea conditions.

In fact Ted has achieved amongst the most efficient catamaran hull designs in the trawler market. The hull shapes are. They are usually metal are heavy have poor efficiency and a poor ride compared to what they could have.

Catamarans also generally have a shallower draft and require. When finding out whats new in this arena theres no one better to ask than the team at Gold Coast Yachts in St. The most important benefit of speed of a multihull is the ability to outrun bad weather.

The hulls must be efficient above all to make the most of a limited electricity supply. I have given this design the acronym SPEED standing for Small Power Extended Efficiency Displacement. Design Specifics the SPEED.
