How does the Torpedo do it?
Posted: Fri Nov 30, 2007 7:16 pm
Alright designer-guys, Im here to learn.
How is it that the Frost Torpedo, as redesigned by some shops in Maine and built at Rumery's, can do 32 mph? It isnt a planing hull by any stretch, it has waaay too much slope in the aft sections (no monohedron), its soft chined, and has a VERY sharp entry. They estimated 15-18 kts, but it ran wildly past expectations.
38' LOA, 9' beam, round bilged, and driven with 315 hp. One of the builders is quoted at being able to get 6gph at 30mph. THATS 5 MPG! Pretty far stretch from the 1-3 most boats get.
Id love to know how it works, because I think itd be an interesting boat to develop in this technique, as it could be an extremely efficient commuter, or with a sailboat-esque trunk, could have vast accomodations.

I know it has similar proportions to the FL26, but It looks to be a very different boat as far as running characteristics, even exceeding a certain commuter by another designer.
