This is probably one of those posts that crops up here pretty
regularly, but here goes.

Having dived, canoed etc, always kinda fancied trying windsurfing.
Long story short, I was given a board for free the other day. My
initial research suggests its a beginners board (good) but possibly
pretty old (may or may not matter). What really matters to me is to
find out if I can get it up and running to taste the sport.

The board is a Tiga but I don't know which one - approx 385cm long (
I'm 90Kg, but from what I've read this should have plenty of
flotation even for me). Only other clue on the board is the number
43004 stamped on the top - and it has an extra (intentional) hole in
front of the mast foot, slightly cone shaped above and below. Boom is
tie on and sail (Arun) has no battens and a small window. It has a
daggerboard, but a missing fin - which brings me to my first
question ...

Can I get a replacement fin - seems there are some standard fittings
around or do I have to ID the board first? The main fin slot is 10mm
wide x 255mm long, with slightly wider cut-outs near each end. Plan
B - could I make one? I have polyester resin and glass mat/tape from
my canoe building.

Next question - seems like tie-on booms were a problem before clamps
came along, what's best practice for tying on?

Just how bad is this setup? Am I wasting my time?

Any info/pointers greatly appreciated.

Thanks

Stewart
