I have a couple more questions:
I believe the GO can have two side fins to help with upwind sailing, would this replace the need for a dagger board in non planing conditions?
If I go with a board that has a dagger board can I put it in the "up" position when I want and plane if the conditions are right?
Is it possible for me to progress on a board without a daggerboard?
How will the various fin sizes effect my sailing and what are useful starts?
