Partly that. But I'm after a US box fin that will double for an 83 lt wave board as well as the centre fin on a sup I've just bought. (it has the windsurfing option but the centre fin it came with is a small one for surfing only)
Now Windaddict, you must have a truckload of old wave fins!!
Yeah I have 1 old Torquay wave fin which came off my first true wave board (a strapper fibre glass custom), its been ground down a fair bit from scraping sandbars, so is not really much good to you.
