The team at Catamaran Guru questions the suitability of this design feature for blue water catamarans that.

Efficient catamaran hull design. Catamaran hull speeds are very high due to several factors. Design Specifics the SPEED. They come from a very conservative design place.

The hull shapes are. 1 Efficient planning shape foil assistedCorsair 22 Foiler. A catamarans Power to Weight ratio or Displacement Length DL Ratio is one of the most important efficiency indicators of a multihull.

Schionning Designs use three hull types for our range of power catamarans each with different design and performance characteristics. 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. Their cruising catamarans use an inverted hull design that has become a signature mark of Fountaine Pajot vessels.

New hull designs like catamaran ferries pentamarans and thin profile boats help reduce wake and increase boat fuel efficiency. With the full hull design some light slamming is experienced on the hulls as they are so full but this is far more acceptable for maintaining average speed fuel efficiency and comfort. The prototype fulfilled the requirement and actually reached 18 knots.

This hull allows the water to pass beneath the ship quickly which increases the speed and fuel efficiency of the ship. Finer hulls are more efficient at high speeds but as weve just seen suffer from more WSA and so for normal cruising catamarans in average conditions a ratio of 111 - 131 seems optimum. Since the engines are more spread apart the boat is more easily able to be maneuvered too.

In modern catamarans the most popular trend. Most catamarans are designed to have twin two engines that can be used to the sailors advantage in navigating the boat. Click here to read more Blu Anda 172 Launched November 2013 by Australian Thai Team was our new Fastcat 18 design.
