It is easy to design such a boat and get the same performance (minus the hype).
To keep it brief, last month, Joel and I participated in a seminar given by Nigel Irens. He explained the theory, nothing new but well applied by him to his Range Boat. Read about it here:http://www.hiswasymposium.com/pdf/2004/ ... 0Irens.pdf
The most interesting part is not in that paper but was discussed with him after wards: why do those boats and plans not sell?
(Range boats sold 2 or 3 units in 4 years!!!!)
Because they have limits that people do not accept (or understand), because marinas charge docking fee by length and because of misconceptions.
People do not accept that those boats must be light and narrow.
See all the questions about the Nina (LB22): can I raise the freeboard, add a cabin, widen the boat?
They often reason that if they have a 26' boat, it must have the same double cabin, galley and shower than in the Bayliner they saw at the dealer.
They buy the Bayliner but since a Sunday afternoon trip cost $ 200.00 in fuel, they stay at the dock with it. In the mean time the Range Boat owner is cruising and cruising and cruising.
They don't cruise but at least they have headroom in the shower.
VSLH are a great concept but a commercial fiasco.
I already designed the LB22, the FL26 is coming soon and if it works, you will see more.
There is no magic in the design. I have many lines plans and specs of those hulls including the Hooper Island Launch and probably the Torpedo. The design is not the problem, the problem is with the choices made by the builder/owner.
There is hope on the horizon: crude oil is going up and we may not be able to afford gas guzzlers anymore.
