If someone can tell me how to post photos, I'll show you what happened last week in Kingston, Ontario. My brother lives on Lake Ontario and the winds unexpectedly gusted to 60-100 km/hour during breakfast on Wednesday. They heard a crash 'n kaboom and when they looked outside, his Tornado was on the neighbour's roof and the H16's mast was bent in half. Ouch. Like my 8 year old son said to me after I told him the story - "I guess Uncle David should tie his boat down next time"....
Only permament damage was to top of one hull near the stern. The corner of the house was pushed through the tramp but it was on it's last legs and about to be replaced anyway.
Cheers
