Lots of undesirable stuff going on.
Highly loaded prop set at an angle to push the boat to one side and prop walk to push the boat to the same side and a small rudder to control the boat's direction. Nothing is offered for directional stability. The rudder is offered to that end but it's possibly/probably already over loaded. A small keel approximately on CG giving lateral stability but no directional stability. The rudder correcting all these stray forces creates more drag than it should and all this together may explain the boats moderate performance. Was there ever an OB version or do you know of any conversions?
As to the flat turns My Easy Rider turned absolutely flat before I put on the cabin. Then it banked noticeably .. not a lot but more than a little. I concluded that raising the CG was responsible so perhaps the low CG of the Shamrock is the reason for the flat turns. The low CG is probably not exactly a bad thing unless you trip a chine and flip.
psneeld I think a lot can be learned from observing and evaluating. Wrong conclusions can be made but as the old saying goes one will learn from their mistakes. So I'm going to keep on look'in, think'in and evaluating.
