Does any one know where I can get a daggerboard gasket or how to make one for a circa 1992 F2 Lightning 377 Raceboard
Or where I can get 2mm thick poyethylene, polymer or vynil?
Extreme lack of wind and boredom have driven me back to a longboard
Maybe ask Windgenuity. They are the current F2 importer and I think they have been the F2 importer for a fair while.

Otherwise fleabay and see if you can find another similar board.
Seriously considering getting such a board. It would be great for some longboard cruising. It would be funny listing such a board on the GPS Challenge site.
go to a sail maker and get some stickyback dacron,some 20mm seam tape ,and some sailmakers sail template mylar, you will need to laminate two peices of mylar with the seam tape then stick the dacron on both sides you will need two of them one each side should cost about $30 in material
you will need to overlap them by about 5mm
Lucky you with a lightning 
Have you tried clark rubber?
Keef does your idea spring back into place after you've retracted the centreboard a few times?
I think a good raceboard will give a bit of a shock gps wise 
Thanx for the replies
Keef after you laminate it all together what do you then stick it to the board with?
contact, what you will find is the dacron is porus and a rough texture, if ive got time ill have a look tomorrow to see if it still has a flap
heres the plap, as i can see it doesnt look as good as it used to but there no kinks and its still nice and flexy and stiff 
The last board I had before going off windsurfing was a F2 Lightning.
the lack off wind drove me to get one. then the wind seemed to just get lighter.
