I don't windsurf anymore, took up kiting last year. But anyway, went through my box of spare bits and pieces the other day and found brand new 20 inch harness lines, 2 spare foot straps (one JP and one F2), an old uni joint (mastbase, uni join and non-adjustable mast foot) and an older neil pryde mast extension protector.
All free to a good home. If anyone is interested PM me. I'm in Sandringham. Pick up only but could also drop it off if within say 15kms.
