Sky Solbach - Waveboard Shapes
AR_Fins?
Sky Solbach_Fin placement is a crucial yet often
overlooked aspect of surfboard design. There is
an infinite number of configurations that offer a
wide range of feel and performance characteristics.
Below are a few examples of different configurations
and their effects on performance.
Thruster (3) fin:
-moving the fin cluster closer together results in
a looser feel and a tighter turning radius.
-spreading out the cluster gives more drive and
hold and results in a wider turning radius.
-fins closer to the tail give more hold and grip
-fins further forward give a looser less connected
feeling.
Quad (4) fins:
-quads closer to the rail offer a quicker rail to rail
sensation with more grip/acceleration when on
rail but a less connected feeling at speed.
-moving quads closer to center line gives you a
more connected and draggy feeling similar to a
thruster.
AR_Introducing more cant angle (fins tilted out
towards rail)?
Sky Solbach_It’s looser and more draggy at high
speed, but offers a connected and direct response
at lower speeds and when pumping to generate
speed. (Good for small waves) - More toe angle
(front of the fins angled in towards the board's
centerline) allows fins to operate at a higher angle
of attack, making them better for generating
speed in small surf.
Developing boards requires a lot testing and fins
are just one of many variables that go into creating
a high performance craft. Understanding the
effects different fin positions have on performance
is key to achieving the correct balance between
board and fin.
AR_What fins do you use specifically for kitesurfing?
Sky Solbach_I typically use a stiff fin with quite
a bit of rake. I like a fin that has a very positive
and predictable feel. I never really liked fins that
