Check out these reverse strakes

That style of strake is much more effective for it's size than having a flat. Directs the water down rather than out providing more lift and a drier ride...

I never drove this boat but with a 155 v-6 buick engine and it did 44MPH, I figured these strakes helped. It's farely heavy and really wide. The hull bottom is 3/4" thick glass.

More lift = more drag, so it might be drier but it won't be as fast as a VDH for the same power and weight. Just like on airplanes, the more you deflect a fluid, the more lift you'll get, but you'll also get more drag along with it, unless you can do something clever to improve the L/D ratio. Moesly's idea with the VDH was to improve L/D by deflecting the water from the keel to the chine as gradually as possible, while also introducing a boundary layer of air to reduce drag. His testing proved that it worked, producing a hull that was about 10% faster for the same power and weight as a conventional constant deadrise hull with flat strakes!

This boat doesn't have much of a V at all. It's pretty flat with like a 6" skeg. Thought these strakes were kinda different you dont see often. Not sure why you guys cant see the pics. I attached them the only way i knew how.

Bushwacker,

I'm very familiar with Moesly's VDR hull design and by no means trying to compare this boat to a Seacraft. But, on most hulls these strakes will add lift, reduced engine load at lower speeds and improved speed and handling at high speeds regardless of the added drag. The attached pictures show similar strakes that were added to a 66' sportfisherman. They dramatically improved it's ride and they are only 5/8" tall...

Hey Big Lew; I got a visual!
