Modern Twin Fin Boards

Recently I watched a couple of guys riding modern twin fin boards. The boards were a Jim Banks Magic Carpet twin which Dave was riding really well in waves up to six foot or so, and a Gary MCNeil twinny that a guy was surfing in four foot waves. I grew up riding twin fins and used to really like four channel twin fins (eg Jet from Byron Bay, and John Stewart from Catherine Hill Bay). I'm not really a fan of the current old School twin fins or fish, however am wanting to try a more modern style one or a hybrid. I like swallow tails but don't want one with a flyers.

If you know of anyone who makes a good modern fish, or have some design ideas please let me know.

Is there any reason most twin fin boards modern or traditional are wider with the fuller outline. “Performance” models from channel islands and MR feature some sort of flyer to break up the rail line and tighen the tail but still maintain the full outline through the nose.

Why so much width in the first place that you need a flyer to reduce the tail area when if you where to reduce the width and go towards a conventional hp shortboard dimensions you have a quicker transition rail to rail with the reduced width, less tail area for the fins to control, and less rail line in the front half of the board.

Not sure about that, but my current Sculpt Donut Dagger which I've had for a year now (still holding up astonishingly well seeing as I surf it nearly every day) is more drawn in and not as wide as traditional twins.

Thought it's nothing like a traditional or modern twin..

@rees0 from my understanding the twin fin design will generally have a fully nose to accentuate the positives of having removed that middle fin.

by having a fuller nose and moving the wide point to or just in front of center the board will have the rails that are closer to parallel. This results in the board having a longer rail line than that of a board of the same length; that has a curvier outline.

longer rail line draws out turns, smooths out transitions and provides more drive when engaged with the wave face. The first two of these help reduce the major negatives of twinnies (twitchy and skatey) and the third accentuates the major positive (speed)

If you were to put a large pair of twin fins in a board with a modern high performance outline you would likely get a board that doesnt feel much faster or more drive and when you really put it on rail it will skip and slide in a much more uncontrollable way than when on a more 'traditional' shape.

I love riding twin fins, the MR Cali twin brings back the fun to surfing in small waves, technically though it does have a trailer fin.

I am having a ball on Black Baron style twin and the big difference between other modern twinnies I have ridden and this one is the bottom and the FCS fins. It is a 'V' bottom but not a flat panel, there is a slight concave in each of the panels. It's starts about half way down. Not my fastest board but very stable and goes on rail really well and banks off the top beautifully and you can ride it backhand. I noticed in a design discussion somewhere, that Brit Merrick is experimenting with 'V' bottom twins. I am thinking of a step up twin with the outline of something like a CI Happy and the bottom of a scaled up BB. For my style of surfing - banking turns, some snaps and carves I reckon it might have legs.

I've recently bought a Jim Banks 2nd hand twin fish which I'm very keen to try out.

Never surfed a twinny before and haven't ridded a fish in over 10 years. Currently locked down in Melbourne though (had a mate pick it up for me in Torquay).

Hopefully not too much longer before I can get it wet.

Yeah I am on the peninsula Bnkef so I have been trying to ride all my boards in various types of surf. Have a CS happy type board 5'10" which I am going to scale to 6' for a step up twinnie. The Happy goes unreal in good waves and shithouse in average ones. Needs some size and push. Trying to settle on an all rounder twinnie which I can step up and down from without too much change to how I surf. Performance Twinnies- get on the front foot early and drive then make sure you are back to turn, quite different to a thruster which is a good thing.

The one I bought has a fin system. The guy I bought it off sold it with a set of keel fins (which he said he found worked best after playing around with different set ups).

Ah thats gd - slip those keels in your D.S. and tell us how it performs
if there the same fin system that is
