As the nose of the VOSPER was pointed almost vertically when going full speed I decided to do some trimming. The first thing I have done is to increase downward water deflection at the rear.
I tried it out last Sunday and it works fine The nose isn't pointing upwards anymore. I do however have one problem left to solve: The VOSPER is leaning seriously to the right as I am using a right turned propeller. My plan is to increase water deflection at right to balance the propeller torque.
