I have a 1986 36 open. It has new(er) caterpillar diesels. When I am cursing at 1800 RPM with no trim tabs at all the boat runs at 23 K. If I lower the bow, the speed picks up and I get an extra Knot. In my past boating experience, when I lowered the bow using Tabs, my speed decreased. What is it about this hull that makes my speed increase with the bow down?
