I am building a 39ft tri.
This low friction fast displacement hull
design is somewhat different than any previous ideas.
The load carrying capacity is towards the stern,which is wide and the bow is long and narrow, no bow wave is ever produced.
The design does not suffer from overloading problems associated with other multihulls. I have built 5 prototypes up to 15ft long testing the theory.
The naval architect has finished the plans, the aluminium is being cut, now I just have to put it all together.
I have a problem with the cost, the weight, and the supposed reliability
factor (Not in yachts, maybe trucks and tractors) and the smell of inboard diesels.
I would much prefer to have two Japanese outboards than one diesel.
Based on previous experiences I expect 15 hp (a 30hp outboard
running at half throttle for economy) will give me a 10 knot cruise
speed. Two 30 hp Japanese four stroke outboards "should" give me 20 knots. (to double the speed you need four times the power)(there is no bow wave formed with this design, only wetted surface friction)
At 10 knots I will have a range of 2,000 nautical miles.
After reading other threads, It does seem strange (to me) to put in a 240volt generator and then spend a lot of time and money
converting it to 12 volts, for storage
. Why not put in a 150 amp 12 volt alternator
coupled to a small gasoline engine
with the proper electronics
I am open to any points of view,
Just don't tell me gasoline is dangerous. which it is NOT if the area is openly ventilated (on the aft deck) or fan forced in a sound insulated container.
