fish fin toe in and cant

Why are fins on most fish parallel with very little to no cant, and what would happen if you toed in and canted out more.

Peace Delayney

I think the no toe, no cant is traditional. In theory putting toe and cant in the fins will loosen up the board a bit. They can be kind of tracky. In my personal experience I have not found this to be true. When I use double foiled fins I don’t toe in or cant the fins. Single foils I cant and toe in a little bit. Build a couple of them and see what you prefer. Mike

More toe-in means the board will be slower going straight, will want to turn more than trim on rail, and you will need to slide the tail sideways a little before the fin will engage.

More cant will reduce hold, reduce turning radius, and increase speed through turns.

Typical toe-in is about 1/8", with only a few degrees of cant. You probably do not want more toe-in if you use keel fins…you’d need something with less base length.

Build it so the tail flexes a bit and the fins will cant and toe as appropriate to the forces applied to them.

a traditional fish is more meant for speed than top to bottom surfing. think of no toe, no cant as 'no resistence, no drag". the more toe the more drag the fin creates.

hope that helps,

I toed the double sided keel fins on my fish 1/8" and cant them 3 deg. Works just fine for me. Fast and loose.

mine are "toed in " towards the nose , thruster style , so I can turn .

A little bit of cant too.

I use mine with twin fins or keels [once , I used both , as a four finner !]

So, for me , with having plugs , it’s nice to be able to change the feeling of how it rides , on different days , and even in different conditions on the SAME day !

Hey Delane,

I’ve glassed four traditional fish for Shipman this year and we cant them between 1-2 degrees.

He marks the blank so I’m not sure what the toe in is. Maybe I can get him to chime in on this thread.
