Dear Swaylockers,

 

I am currently reshaping an old windsurfer. it had this fin and these boxes. What kind of system is it? is the center box compatible with US Box fins (I unfortunately don’t have one so can’t compare)? I am thinking about putting the box into the board i am shaping… the fin is giant, I’d have to resize and reshape it i guess… Thank you for your input.

im pretty sure those type of fins just click in and out of normal fin boxes but sometimes sanding those plastic fins is a bit of a pain in the you know what.and yes you can use those boxes if you have to but it is a good idea to have the fin and the box your useing before you put box in make sure all fits.if this doesnt work ill eat my hat.
