Te whole thing with the spin out was true for some of the very deep Vbottoms that ran very far up the bottom. I believe boards like Midgets were a little more thought out with thinner rails.Matavish testing them in Hawaii did show that they had limits. The other problem is that everybody jumped on the design without a clue as to what they were doing. The V ended up being tossed in the bin of failed design. In the last 10 years A few brave souls started looking at the V. Working on blending and balancing the effect of the V into an over well preforming craft. It is getting a following. It seems the newer Boards that a few dedicated Shapers are building do sell. My personal opinion is they work as a quad or with a long narrow flex center fin. No expert here on V bottoms I just like quirky boards. Been thinking a lot about a V bottom Fish style board. The blending of the two might just make fun Board. Fish like to turn off the rail and the V would get you on to the rail. That’s my story for now. Might even stick to it.
