Just an observation, no comment on type of boat
We were beating up wind
, 25kn TWS, he was comming up behind us in a big cruising cat and lifted the hull
often, occasionally it would hang up for 3 or 4 seconds then drop back down. There was wind
against tide and the steep swell up to about 2.5m most around 2m.
We rounded a mark which took us off the wind about 10deg and bought the swell around to more side on. It lifted the windward hull
like it did before then suddenly it shot up further to about 40° hung there for a moment like it was balancing on the edge and fell back down.
It was so fast, if the sheet is on a winch
you would not have a hope of doing anything about it and I doubt the helm
would shift the dynamics of the boat
in time. The only chance you might have is if you were holding the sheet with a couple of wraps on the winch
and just let it go.
I guess there are all types fast and slow but it was a real eye openner to see what might have happened.
