Wayne. Its what we build these thing for, bunging them in the water and giving them a good thrashing. Or at least, all my boats get a good thrashing.
When you say "slow off the plane" do you mean it is slow in starting to plane? or the rudder is an issue??
Nerves. Built in buoyancy and a method of recovery are what`s needed to calm nerves!
Picture would be nice if poss. Cheers
