Warp drive fin ride reports from Steve and Jaffa

Recently Steve rode a 7 inch Warp Drive Bumpy leading edge foiled (BLEF) spitfire fin.

The fin is easy to install, so here it is in a Campbell brothers Bonzer:

Steve added the fin to a Campbell brothers Bonzer, with side runners

Steve Day 1


"Tested this morning in cleanish 3ft runners in board as above.

Had no idea how this fin was going to go, none.

It was very, very free. Loose. A close to finless, drag-free feeling.

Completely changed the handling, reaction time and turn dynamics of the board, in not a bad way.

Board was now super fast and pivotal, wanted to go straight up and down.....and had zero anchoring effect....you had to stay right over the board through turns....it frequently went through the turn without me as I figured out the reaction time of the fin....which led to plenty of keystone cop arm waving as I recovered.

It didn't like being pushed through a long hard carving arc...it wanted to draw shorter, snappier arcs, although if you carefully weighted rails it would draw the turn as described.

Altogether a very fun, freeing, pleasureable sensation. Totally different to what I expected, which was nothing.

I could imagine the fin suiting a board with a narrower tail, as is Roy's design philosophy.

I'd like a range of fins, one slightly bigger with more area for when you need more hold.

Altogether though, Roy is at the forefront of a revolution in terms of 3-D printing and small scale manufacturing and I reckon this product works. I had a blast on it and can't wait to get out on it again.

Steve Day 2 

Surfed it more now. In quality step-ladder building Point surf. And fun, dribbly left wedges at tallows.

There's deffo something new, something good and something free and easy happening here.

On the small lefts, it got up to planing speed very quickly; had that same drag free yet lifty positive sensation as backhand. The fin feels drag free yet not in a neutral way....you can feel the fin at all times...it provides

Lift makes the tail ride higher, enabling cool fresh lines to be drawn

lift that tends to make the tail ride higher, and with the increased pivot that enables some really cool fresh lines to be drawn. 
I'm really digging this fin. 

It's sensitive, as all singles are, to fore/aft adjustment in the box. Thanks for that tip Boo.
seems like some extra sizzle in the steak caused by the tubercle leading edge and width of the fin......xtra lift and drive?

" I'm really happy with mine, and the Bonzers fins with the future base for one of my other boards.
The BLEF fin is fairly squirrelly if you have it too far forward in the box but if you pull it back about 2" from where you would have a 9" cutaway, it really gives a nice point around which to pivot. Paddling is pretty drag free compared to a thruster or even a 2+1 set up with Bonzer FCS fins as side bites.

I found on my 9ft Outer Island I had to keep drive on it throughout the entire turn and it handled good hollow Merimbula without  much fuss and was able to holder a higher line than I would consider on any other single fin.

Conclusion: I like"
