Windsurfer fin for longboard

has anyone ever tried windsurfing fins in longboards? I just scored this here and wanted to give it a try. it’s a bit more than 8" in depth, the base is 5,5" wide.

it’s another month till i get to the ocean. I wonder if it will work. I am building a 9’ / 23" longboard at the moment. as the fin was not that expensive, i consider cutting a new outline out of it and refoiling it. is this worth the hassle? or would this fin be a good starting point for my longboard?

I do not believe this fin is handfoiled, I’m quite sure it is CNC milled.

Altough the fin states that is is custom, I believe that it is a fin that comes as a standard with a Jason Polakow wave board.

 

Do you live far from the northsea? There is some swell coming this weekend. Not very big, but places like domburg, maasvlakte or scheveningen could be very nice for testing your longboard.

It can work very good.

However, I can not say if it would work with your board, weight, …

You should test it.

I think that the fin will be too big.

 

If it doesn’t work, cutting it and refoiling is a good idea.

Hi Hans,

 

you’re right, more info is needed. I weigh 82kg (180lbs), the longboard I am shaping has the following dimensions:

length: 9’

width: 23" a bit foreward of center

Nose 12" up: 18"

Tail 12" up: 15"

thickness: 2.75"

Nose rocker: 4.5"

Tail rocker: 3.7"

 

Will this be too much fin? I will surf in average beachbreaks. atlantic summer swells.

That should work fine

I’ve used wind surfer fins of all types (Curtis Fins/BC Rudders) with no problem

I'm in full agreement with Bernie.  It should be A-OK as a longboard single fin.  If it makes you feel better, wet sand the logo off, trim the trailing base a smidge, redrill the pivot pin hole and call it a surfboard fin.  Nobody else has to know.

Johnmellor, Oneula, thank you for your replies! I was hoping for that! the foil of that fin is actually nice and the guy who sold it to me said that it was handfoiled, so I only wanted to grind it down if the sway folks agreed that it wouldn’t work. awesome!

Hi Hans how was the weekend? I live too far away for a weekend trip, unfortunately. The closest wave is the river wave in Munich :slight_smile:

It will the FRANCE in August, can’t wait!!!
