Hi I have a 6"8 x21x3" sting with no fin what size fin should I use in it
Eh,
Silly rabbit!
measure from center/center of fin box to rail edge.
= length.
But most singles will work…
Thank you very muchly rode this morning for the first time with a 6" fin was to small will measure and try again
Measured a few of my singles, and I run about 20% more length then mid box to rail. I do tend to surf more off my front foot though.
If you want to go Rubberman style it’s gotta be all the way forward and a little loose in the box for extra snap.
