Hi ,

The boat is located at Espoo Finland. You are welcome. It is easier to
turn the fwd rudder than lift it. Thts what I am adjustin all the time.
I will come to the rudder foils later. They will benefit from some fine
designing. I am keepin the down all the time, so I migh taper them.

Regards,

Arttu

you consider/try raising the front rudder instead? that seems easier to
me.
