The Havana 38 Express as well as the Havana 40 was designed by Clark E. Boeken, the director of Cruiser Cats, the hulls being based on Malcolm Tennant’s design. His designs are well known and tested semi displacement hulls for multihull boats.
The new generation Havana 42 Powercat was designed by Clark E. Boeken with the help and guidance of the well known yacht designer Phil Southwell.
Our Havana Powercat line and our entire range of power cats have semi-displacement hulls. These hulls are based on the Malcolm Tennant design. Powercats with these hulls can achieve great speeds with minimal fuel consumption and very little wake.
Here is a little background information on Malcolm Tennant and his Powercat designs.
Malcolm Tennant’s lifelong involvement with multihulls began at age 20 when he purchased his first beach cat in 1959. His hobby became his profession when seven years later Malcolm began designing and building A-class catamarans along with two friends, and later became a licensed builder of the Olympic Tornado.
In 1983, Malcolm made his entry into the world of power catamarans. Building on his design of the Cordova which was a motorsailer that could motor at 18-20 knots and yet sail at 24 knots, Malcolm made the leap to a an entirely new hull form that is now the standard in displacement powercat hull shape.
The CS Hull with its canoe-sterned underbody with a square transom on the water's surface and fine forward entry angle, has become the signature of Malcolm’s powerboat designs and has been adopted by many.
Malcolm had a lifelong passion not only for boats but for learning the ‘why’ behind everything in life with interests that stretched in many directions. It was this thirst for knowledge that always caused Malcolm to look beyond first impressions and to see what aspects of the design really contributed to its success or weakness and to build this into the next vessel.
