While learning, I bent the fuselage running aground, bought a new one, bent that, got it straightened. Had to keep trimming a centimeter off the mast to get the rounded edge off.
Then snapped that board slamming into a sand bar fully loaded mid-gybe.
Dinged the rail of my third board putting it in the car, then a hole in the bottom of the board (how?!?!) hitting a rock...
Hit a breakwater wall that had sunk under the water... front wing got a bit of a ding in the LE but sadly a slice through the skin on the bottom.
Discovered cracks in the skin of my pocket board, got them fixed professionally, then a couple of sessions later discovered they'd come back.
The worst by far though was borrowing a new Tray board and hitting a half-submerged plastic bag at high speed Creased the board. At least now, it'll be stronger than ever!
Oh and second session my latest new wing, I fell off and the board sailed into me, and the wing hit my spreader bar and put a tiny chip in the wing
