AUS1111 said...It's not from the Olympics - if memory serves me correctly the board used in LA was the Windglider (I was only a nipper). It's probably from the Windsurfer Worlds which were held in Perth in the early/mid eighties.
Incidentally, it would be utterly worthless

When it comes to vintage windsurfing gear, unless you have a Windsurfer One Design from the early 70's with the teak boom etc. in MINT condition, I don't reckon you'll find too many takers.
Windglider: that was Olympic racing in 1984.
But there was freestyle and slalom as a demo sport, on old one-design Windsurfers. As far as I'm concerned, it was more competitive than racing on the Windglider log. Sail on those freestyle Windsurfer was the same triangle sail as that one, although that one in the picture looks like a lawn pizza.
Value of old one-design Windsurfers: still used for teaching and farting around and social sailing inland, as in North America, in lesser winds. Whatever works.
Good for non-planing freestyle (and some planing) and good for general shape until the wind picks up, in the 10-15 knot range.
