Twin Fin

(5 reviews) Write a Review

Rusty designed and built a Twin Fin for Josh Kerr just prior to a trip to Norcal... to say Josh loved it is putting it mildly. Starting with a template Rusty used in the 70's & 80's while working with Shaun Tomson as his base Rusty refined the bottom with the addition of a shallow single concave that feeds into the vee. The vee splits into a double in front of the fins and runs off the rail behind the wing. The position of the wing, the back of the fin in conjunction with the concave exiting through the wing makes for solid firm turns. The foil in the rail line is very similar to a modern performance shortboard. Don't think of the Twin Fin as just a small wave board, Josh rode his in some pretty solid head high barrels last winter and loved it...

  • Twin Fin

    Posted by Joel P on Jun 5th 2020

    Good Board! I've been riding a keel fish in smaller/flatter stuff and wanted to get a twin with more performance (less multiple adjustments to go vert,), handle steeper surf, This thing is fast with performance... so fun! Get one!

  • Reinvigorates your surfing

    Posted by David on Dec 14th 2019

    I’ve ridden this board about a dozen times now; surf ranging from 2’ up to 6’ at my local beach breaks and it is a load of fun and extremely refreshing to ride. Have been surfing close to 40 years now, most of that time spent on tri-fin boards. This board makes me feel like a kid again fast, loose, paddles well, has put a smile on my face a number of times. If your quiver is full of the standard shapes I suggest adding the Twin Fin really adds a new 'feel' to your surfing.

  • Modern Twin New Go To Board; Twin Fin Placement

    Posted by David Robinson on Aug 5th 2018

    I love this board! If you read nothing else, read this. You cannot really have a twin fin by taking out your third fin from your tri. Ask Rusty (thanks lPedro, thanks Clint) but basically especially the placement of the fins plus the bottom flow make a difference in this modern twin. I'm so happy with this choice. Thanks all! it surfs great
    Since I've had it 5 months and have ridden it in everything from knee to overhead, Oceanside to Mazatlan... it has become my go to board. I think that's saying a lot since my last go to shape, I came back to for 7 years.
    Also need to mention, I went all out on my art requests and their airbrush guy game me exactly what I asked for... thanks for that!

  • Fast & Loose!

    Posted by Ramge on Dec 10th 2017

    Very Fast and holds incredibly well, Gets loose when you want it too. Easy to put on rail and for the back footed surfer goes vertical in the pocket. Has a wide range of surf it will work in from Knee high Shores to Over head barrels at Blacks. Very Fast Very Fun!! Great Addition to have in the Quiver.
