Since the expert's here, I have another question. Any ideas on how long to keep the sponsons straight, compared to what TBDP predicts for wetted length? Right now I've taken my lowest corner exit speed, added a little to that wet length, and then started the bow curve. I suspect longer sponsons will help in rougher conditions. I'm also trying to keep from dragging too much over the water when the boat comes out of the corner with little positive trim. I'm sure handling is affected but prop height and setup should keep it manageable.
