I know it's not new, Tony, and I have gawped at the odd Moth in action. It's just that Lasers (which don't slouch, given a bit of wind) are two-a-penny, and the sight of one on stilts leaving a 'normal' Laser absolutely standing is pretty amazing - well, I thought so anyway! It does seem a neatly done add-on, as you say.
I think I'll stay floating normally - just as I prefer a boat you sit IN rather than ON. But I must say that, in spite of myself, I found myself intrigued by, and then hooked on, the America's Cup TV coverage last year. If I mention the naughty words 'match fixing' in that context I'll probably be sued for libel, so I won't mention them: but whatever, it was pretty compelling viewing. Whether it was sailing, at least as i've always understood it, is a moot point. And I still don't understand how they can do 40 knots in 20 knots of wind (no, don't try to explain, I'm past all that. Resigned sigh.)
What has this to do with 'Winsome'?
