RE: Gybing a 150 to 175 liter board.
Hi sorryfor delay in replying, yes I owned a Samba, but have extensive experience on a Bamba (Raceboard). As Roger has said its finding the sweet spot to do a pivot jibe, practice sailing downwind then move back sinking the tail a little more each time until it becomes natural.
