It's a bit hard to get good photo's in such narrow hulls, and he has bolted down the original access hatch
We went out again on the weekend, fantastic, we were accompanied by a Mariner 34 which is a typical planning power cruiser.
Both had Steyr motors.
The Mariner had replaced two 130 hp diesels with two 265 hp Steyrs, the Steys were considersbly lighter than the original motors even though they had much more power.
An interesting calclation, the Mariner had a power to weight ratio of 60 Hp/tonne (a planning hull)
The power to weight ratio of the Catamaran
Both do 20 knots
had a far better motion, cutting through the waves not over the top.
Does anyone else out there have experience with fast displacement
hulls and the power to weight ratio in use.
Today I will be checking on a fast displacement ferry
range (Citycat) to check on there p/w ratio. I am of the opinion with better hull
design we can get the P/W down to under twenty. (the grainger cat was designed as a sailing boat)
