IIRC the idea was to introduce air bubbles across the bottom. They suggested it was like the laps on a viking ship which apparently kept air bubbles under the surface along the seams or something like that. Saw some discussion of that. *And the engineers pooh-poohing it, since a golf ball is flying though the air. Also saw that Dennis Connor was wet-sanding the hulls of his racing boats and when asked why, he said "Because everybody else is doing it." They actually have some claims for this boat, but it might be all PR. Seems as fuel prices rise, they could get some traction if their claims are true. I imagine a big cost of sportsfisher operation is fuel, and cutting that cost would be a boon to business. But maybe tradition works against trying anything new. --Vic Fluids all act similarly when you are talking about flow across the surface. Mythbusters actually did show some improvement when they dimpled a car body.- Hide quoted text - - Show quoted text - Hail damage? |
