Hi there - I bought a Sportiva 11 way back in the very early 80's and there was a promotional giveaway of an Alfa Romeo logoed sailboard.  I've never used it and it has been stored in my garage all these years.  It's clean-out time and I will have it removed unless there there is an Alfa enthusiast who wants it or knows someone who collects this type of Alfa memorabilia.

I can be contacted on gregsonexecutive@bigpond.com
I tried to post photos but couldn't get it to work so happy to email snaps to anyone interested in seeing the big beast.  Location is Caulfield, Melbourne

I too have one of these sailboard sitting in the shed. Location Ballarat, Vic.
If anyone has any interest in it let me know.
