Owner’s Comments
Designed by Shuttleworth (design was brand new not “old stock” modernised and updated. The idea was to achieve a power to weight ratio proportional to a 40’ version of the Seacart 30’. Floats ended up being 315% buoyancy compared to 350% for the Seacart floats but Shuttleworth calculated the reduction in air draft and wetted SA in light airs and downwind would improve performance.
The VPP predicted that Morpheus would be 10% faster than the Seacart on all points of sail but we actually ended up with a boat that goes upwind at a max speed of 16.5 knots, tacking through 90 degrees (with the Main hull just clear of the water), under complete control.
Initially we had problems with rudder cavitation but after bringing Hugh Welbourn in and having him design a bespoke set of foils for her, we then had total control right up to 29 knots boatspeed downwind.
