whats a stepV hull

[chumbucket]

They may all look alike (somewhat) now, but that wasn't always the case. C. Ray Hunt (the man behind the Wellcraft V20 design as well as many other cutting edge designs like Bertram Moppies and many more) essentially brought the deep v hull into the modern age of hull design utilizing a variable deadrise running bottom along with reverse chine lifting strakes running longitudinally. There are several other fine variances of his designs, but his is the one that set new world records with the Bertram Moppie design.
Here's a good read on some of that history.

Interesting stuff. ;)
btw; take a look at the Surfhunter 25 od the second URL that I posted and tell me that's not a V20 on steroids. Beautiful boat. I always check them out at the boat shows. ;D
