We had ours blow sideways on the trailer since we had forgotten to secure the bow to the trailer. The keel stayed in the track, so that's probably what saved it from coming all the way off. We had also left the jib up and had the jib cover, so that was a little too much windage and blew the bow sideways. Still got a puncture in the bottom when it ended up resting on the u-bolt that holds the leaf spring to the trailer frame.
Curious how you got it back on the trailer from that point? Mobile hoist or crane?
