The M2 45' is an asymmetrical planning HYdrofoil SUpported CATamaran, capable of speed, efficiency, sea keeping, range and comfort.
Combining all the advantages, the HYSUCAT Concept brings with the latest modern and practical styling exterior as well as interior, places this craft in a league of its own. She is available in a Sport Cruiser as well as a Sport Fishing or an Open model.
Power plant and drive system options range from 250 hp to 440 hp diesel inboard motors with a choice of `Z' Drive, Jet Propulsion or Surface Drives. Performance with a pair of 440 hp motors and surface drives will attain speeds well in excess of 50 knots. Twin 315 hp motors with stem drives will give up to 45 knots with craft weight at approximately 7 tons.
At around 12 knots the craft will get onto the hydrofoils,
The Hydrofoil Supported Catamaran is a hybrid of a catamaran hull equipped with a hydrofoil system between the semi-hulls which carries a part of the crafts weight at speed.
The efficient load carrying capability of the hydrofoil system in combination with the inherent stability and pleasant sea keeping properties of the planing catamaran results in a most economical high speed surface craft with excellent sea keeping behavior. The specific hull design is an asymmetrical catamaran hull with a center-pod rounded tunnel. Specially designed and patented spray rails which were incorporated into 24 degree dead rise hulls.
The HYSUCAT Hydrofoil System was developed by Prof Hopper at the University of Stellenbosch –RSA- .
The system consists of one main wing shaped Hydrofoil bolted between the keels of a Power Catamaran or Ferry, close to the center of gravity of the vessel, and two stern Hydrofoils mounted in the tunnel near the transom under the waterline.
As the Catamaran increases speed the Hydrofoil system produces lift forces which partially lift the boat out the water and thereby reduce the wetted area of the hull.
Due to the fact that the Hydrofoil System carries the weight of the Catamaran more efficiently than the hulls themselves the boat goes faster with the same engine power (20 - 40% faster).
It has taken more than 15 years to perfect the shape and the positioning of the Hydrofoil System and therefore all vessels fitted with the system to date have been successful.
HYDROFOILS ADVANTAGES
- Increased top speed with existing engines (by 20 - 40%)
- Wetted area resistance improvement of up to 45% compared to normal boats in high speed operation
- Smaller engines can be fitted to reach present top speed
- Reduced fuel consumption (by 20 - 40%)
- Increased traveling range (by 20 - 40%)
- Improved sea keeping in rough seas - due to the dampening effect of the submerged foils
- Drier ride in choppy seas, no chine spray.
- Faster acceleration from one speed to another
- Increased payload carrying capacity with less speed loss
- Reduced wake size at speed
- Increased hull strength (keels being bolted together by the main foil)
- More responsive when turning at speed foil borne
- Bank at speed more like a monohull.
- Low maintenance - no moving parts
