I'd like to see a picture of the rear of the hull from underneath. Where do the inner-most strakes end? My Rapid Craft is a very similar design from the looks of it. My inner strakes end 17" forward of the transom. Despite the naysayers (myself included), it actually drives very well into the low 70s. Can hang it there all day in comfort once you're used to it. Not being bashful on the up trim buttom and getting the courage to let it get opened up seems to be the secret. Dilly-dallying around in the 60ish range with just slightly positive trim is very frustrating and many people would quit right there because they wouldn't believe that it is more driveable and predictable at higher speed with more trim. Not saying a Sidewinder is the same way but the design looks pretty similar. My hull is longer though...plus I'm still relatively young and there is a fine line between talent and stupidity.
