well i didn't break anything but had a horrible session.
rigged the 5.7, had a few good runs and then got hit by a crazy gust.
beared off to for a huge broadreach which ended in a catapult after the board got airbourne.
when i got back to my gear the sail was pointing at the bottom with the board upside down. spent the next 15 min struggling to get the sail to the surface. eventually got it back and waterstarted totally buggered. sailed back in and stood on the shore gasping for breath.
20 min later went back out again. totally overpowered, gybed off, got hammered. same thing again. rig sunk. 10 minutes later i managed a catapult waterstart, rig sank again. got it back up and sailed back in to call it a day. physically destroyed.
half hour later derigged and had 5 litres of water pour out of the mast when i pulled it apart.

the strongest gusts were around 4pm where it came through at about 35 knots.
