I have a NACRA 14sq. It is a one sail boomless boat. When I bought the boat it had a heavy weather helm so I move the mast forwad. It almost seemed worse.
The boat has a name for wanting to bury the nose and my boat certainly displayed that characteristic.
I decided to move the mast right back as it is my basher and I would fix the rudders after establishing best mast angle.
Why has the weather helm gone?
The boat is sailing very well in the heavy and no NACRA people have answered the queery. mast back, LESS weather helm?
