Performance twin fin

Hi,

I am planning on making a performace orientated twin fin but am unsure about fin placment and cant angles(im assuming 5 degrees)? What would you reccomend?

It would be helpful to know where you are located, ie; kind and size of waves you’ll be riding.        Have you settled on your board dimensions yet?        The best TwinFin boards I’ve ridden had zero toe-in, and zero cant.      Fin placement is the key to both speed and performance.     

Well, that’s interesting!  I know very little about twins, curious to know more, would like to try building one someday soon.

I once had a 5-11 fish twin I loved, back before I started building boards, and back when I could still ride a little board like that.

Can a twin setup work on a bigger board, i.e. 8 foot range?

Bob Pearson is the man on twin fins in the big stuff, peep his stuff

Contact Swaylock’s forum member, Lankameese.       He has an 8 foot twin fin,(Twingle) that he rides in Florida.      He can speak to his direct experience.

This happens to be a big version of a High-performance twin I build.

6’6" x 21" x 2-7/8"

Fins @ 9",  1-1/4" from rail, 8 Degrees cant.

Barry those dots really play havoc with my eyes!  But the board looks beautiful, any toe-in on the fins?

Fins are towed in 1/4".

I just finished my ‘modern twin fin’ (Twingle) and I’m already thinking of doing another one, bigger. The best way I can describe the ride is kinda vague: “like a single fin but grippier”. I have it on a small but thick late 80/90’s 5’8" shortboard. Next one will probably be a 7’0 egg/pig.

 

Also, I’m a shed shaper, so please ignore the burn throughs by the tail :slight_smile:
