Fins

DRIVE

Acceleration, projection and speed through turns.

Fins with a wide base have a lot of drive, feel powerful and stable but are harder to turn.
Less base width feels more responsive and easier to turn but offers less control. A wide base suit shorter wider surfboards with less rail line.
   

HOLD

How easily the fins release in a critical position or turn.

If you want to blow the tail or push a turn into a slide then you need the fin to release more easily. If you want to carve long arcs and like to feel engaged through turns then look for a fin with hold.
Note, less hold also means less drag so smaller fins are faster but offer less control.
   

PIVOT

The length of the turning arc.

For beach breaks or vertical surfing look for an upright fin to allow sharp direction changes, ie. a loose feel. Fins with more rake are better for point breaks, larger waves and long fluid rail surfing - carvey feel. Upright fins with less rake are better for small wave boards or grovellers. Good wave boards and step-ups are good with more rake.

FIN CANT

Cant is the angle of the fin relative to the surfboard base. If a fin is perpendicular to the base ie. vertical, it has a cant of 0 degrees. More cant creates more responsiveness, less cant feels more powerful.

FIN TOE

Toe angle, or Toe In is the direction the side fins point in relation to the stringer or centreline of the surfboard. More toe in feels looser but adds drag. Less toe in is faster with less drag but is harder to initiate a turn.

FIN SIZE

Advice for beginner surfers: if you are between sizes - a larger fin will give you more stability to start with. A smaller fin will turn more easily.

This size chart is provided for guidance, with personal preference and surfboard style not accounted for.

FOIL

Fin Foil has a huge bearing on performance affecting lift, drag and flex. We developed unique CAD files, 3D printed prototyping and custom RTM tooling to guarantee the right foil for the fins. 

MATERIALS

RTM is the most accurate, controllable process, providing the best flex to weight ratio fin. Composite layers are placed in a mold before being injected with resin and pressed. We cut our own tooling for each fin in each size to get exact accuracy to our designs. Longboard fins are solid fiberglass for strength.

FLEX

Flex affects stability, drive and how lively a fin feels. The right amount has both powerful drive and springy release from turns. We control flex through the RTM layup - a naturally medium flexing construction and foil, with a thicker base for stiffness and thin tip for flex. 

THRUSTER

The most common fin set up is Thruster: 3 fins of similar or equal size. These are the most stable and predictable, a good all round style and the go to for most shortboards, grovellers and surfboards designed to fit a range of conditions.
   

TWIN

Although historically the Twin preceeded the Thruster, think of a Twin as Thruster without the stabilising back fin (but larger side fins to compensate). The result is a much looser feeling board, able to turn much more sharply with a single pivot point on each rail. Twins are especially good in small wave boards.

QUAD

Quads sit somewhere between a Twin and Thruster in board feel. The lack of back fin makes them a bit looser than a Thruster, but the additional fin on the rail makes them very drivey. Quads are fairly versatile but especially suit fast, down the line waves and barrels.
