From a born again windsurfers perspective I think there may also be another factor at play here.

I sailed prolifically during the 80's and have only just restarted. There is such a bewildering array of kit you can buy now compared to how I saw it back then. Also there is so much second hand kit it is almost a buyers market. This has tended to lead me to try and buy cheap as I can so that I don't spend shed loads on something not right for me and also tomorrow something similar will be up for sail on the numerous sites including ebay.

Not much help to your sale I'm afraid and only my humble opinion.

Cheers,

Dan
