Sure, when I'm windsurfing at sea above 30 kts, I've met the last 10 years more and more sailing yachts. Reefed mainsails, stormjibs, etc.
Look at the round the world races.The skippers are looking and waiting for stormy winds!

On a windsurfboard it's easy: you just have to pick the right sailsize. Down to 3.2/3.5 in the second half of 40+ kts. So, why shouldn't you do that on a beachcat???


I can only speak for sailing on the North Sea and there the limiting factor for 30+ is normally not the wind but the waves and the break!

With a beachcat you cannot pass a break anymore with breaking waves above 3 m. and a relative distance of less then 10 m.
On my sailing spot you have very shallow waters and even a few miles outside, the waves can still break in high winds.

That's the disadvantage of a sand-shore break versus a reef-break.

Last: when the wind is reaching 30+,the cat is often becoming very awkward to control on the beach. It starts to bounch, sailing on the sand, sometimes capsizing on shore. The sails are shaking and jerking, etc.

I have at least two old mainsails, but I never felt the urge of downsizing them to stormsails.
But I certainly would have, if my sailing spots where inshore water.
