Introducing a new fin system:
SurfTrux. The basic idea is that the thruster system is very
good. On rail, the combined actions of the rear and inside rail
fin cannot be beat. That is the first principle of SurfTrux:
don't mess with the rear and inside rail fin combo of a
thruster when turning. The second principle of SurfTrux is:
At all other times, let the rail fins orient in toe-in to the
water flow to reduce drag. The fins rotate in real time in
between every turn, around an axis near the front of the fin. The
fins never toe-in more than the end-limit, which is set at
installation, usually at the normal toe-in angle. This has two
main effects on surf response. In turns, the outside rail fin
folds away from the water flow, so you turn SLIGHTLY faster and
SLIGHTLY harder than a thruster. In between turns, you can adjust
trim angle to adjust speed. If you stay hard on your rear foot,
it is exactly like a thruster. If you lean forward, the drag
releases and you take off like a rocket. It usually takes many
sessions to learn to lean forward to your advantage. SurfTrux has
the turning power of a thruster, and the ability of a singlefin
to alter trim angle to adjust drag. US Patent 7,001,236.
The
advantage of SurfTrux over the thruster is large and substantial
in small waves, and more minor in double overhead waves. There is
never a penalty for using SurfTrux, but in double overhead waves
you may be underwhelmed. Going backside, the board will be a
little more rail oriented than a thruster, so move your rear foot
a little towards the inside rail. The system does allows all
three fins to be fixed so it will be just like a thruster.
However, other than for testing purposes, no one ever leaves the
rail fins fixed, because every tester notices, and likes, its
advantages.
