Funny old thing...
See other post re stackpack on swinging mooring in high winds..
Saturdays gales here (Nearby Polruan NCI RECORDED GUSTS OF OVER 60 KNTS) Older BR 20 moored not far from me (NOT Gladys! She was ok) Name and owner unknown, lost his main mast, sail etc over the side due to some sort of rig failure it appears.
I was told the wreckage was recovered off the sand banks at low tide and put back aboard, by dog walkers acting as salvors.
Nearby Wayfarer blown over and swamped.
We actually had surf breaking on the sandbanks in the river, with the first of the big spring flood being against the wind. Luckily the wind moderated a little before the biggest tidal flow.
So, be prepared, even in Cornwall in August!
