The balance of all the variables is pretty tough to meet. As the boat gains speed, it also wants to get lift because of the aerodynamic design. But the boat has to be built such that it won’t launch and flip over throughout a range of speeds. I imagine the engineering is quite complex and therefore much more expensive to put into practical use.
@lucillelucillelucille Yeah, Penn Yan makes them, but you asked why more boats weren’t made with them. Penn Yan has probably worked out all the kinks whereas another company would have to recreate the wheel, so to speak.
I want to get this straight. I understand that the tunnel hulls are great for shallow drafting, but I thought they required twin counter rotating screws installed in twin hulls, and are thus considerably more expensive and impractical for smaller boats.
@Tropical_Willie -I read it through a few times and saw that it said expired. (jk! I just saw expired) :)
They don’t have a lock on that idea though as I have seen it on cruise ships.
