Dan,
The only negative affect is that with the direct drive the motor sits too far forward. This causes the boat to surf in big following seas. The deep v and aggresive entry of the SeaCraft cuts into the water and the back end being flat glides. As you know something with out traction (friction) wants to out run something with traction ie. the back end of a car coming around the front on a wet surface. The same hull with a Volvo DP stern drive or jack shaft does not have that problem as the weight causes the back to squat down in addition to the duo prop system having excellent "grab" in the water due to the push pull props. I would like very much to see up close pics of your hulls entry from the side, front and the transom profile from the back. Every 27' I find on the internet is either bottom painted black or is too dark to discern its shape. It looks like the bow entry of the 27' is not as aggressive as the 23', 25' and 32'. Thanks for the compliments and interest in my dad's former boat. I have also added 2 pics of a small striper we caught on November 05' on the last trip before the boat was sold.
Aloha, Greg
