that boat was going over no matter what. when someone is in front of the forestay the game is over and if you are the one still at the back of the boat pick your exit strategy.
Unless clipped into a chicken line I would think it would be pretty impossible to trim in the spin when you stuff it because all your effort is in not flying forward when the boat slows down so much and by trimming the spin in you will be pulling yourself further forward.
Timbo- on a blade when you stuff you are toast- especially if you are solo and can't drop the trav- very unlikely to come back from that. The N20 is more forgiving and when you stuff you can save it especially if you've got a fat bastard at the back of the boat.
