Re: horsepower question
There are some things that only a pontoon can do,skiing and tubing isn't one of them.I don't think it is too much of an exageration to say a pontoon will cost twice as much to ski behind.A pontoon driven within its design limits will
get as good or better mileage as a regular hull.running below about 9 mph.
other wise will use about twice the fuelto go the same speed..Have you given any thought to a deck boat?
