I Have a cav plate that came with my 20.5" Campbell as extra parts. I would like to install the cav plate it has eight turn buckles and it's open in the middle 16". The boat bottom has a 4" recess. the transom has a slight radius 2" from edge to center so it is not straight across like a Flat bottom? Would this radius cause the boat to fishtail at high speeds I had thought of selling it, and just use the Bennett hyd that is already on the Cruiser.
