Broke off while sailing along. The screws have broken off down inside the inserts. I tighten the screws every time i sail as i do sail up to 20k's in an open lake - so wouldn't like to pull out in the middle. Would have had board for 6 months before breaking a screw and now have broken 3 - so it seems to me to be bad screws. Have had 5 starboards and found the screws always seem to loosen over time but not snap off in board.
