This video makes me cringe.

Not because of the boat. I't s fine example of a 18² flying around. Nice and fast boat.

What makes me cringe is the woefully inadequate equipment for the crew considering the conditions.

First wear some kind of buoyancy aid. I believe it is mandatory almost everywhere in the US for kids.

Then make sure your equipment actually fit and never let a meter of strap float away ready to be caught on something.

Don't sail barefooted. At least get an old pair of trainers. I've seen mangled foot from landing badly in a capsize: that's not pretty.

And I'm not even going into the long term issues like sleeve protection or the absence of decent hats or the lack of sunglasses for the young lady there.

But nice boat.
