Captain Fin Christenson Surfboard Twin Fins - Honeycomb
Template: Drive—updated slightly upright keel for more control in your retro twin.
Compatibility: Futures (Single Tab)
Chris Christenson takes us back in his time machine with this classic surfboard keel fin design. The Christenson Keel Fin is a fibreglass template that's a touch more upright than a traditional keel making them more versatile for down the line speed and control in the surf, which will complement your retro twin fin fish, while offering a little more down the line speed and control.

The Keel Fin configuration can make your surfboard fun, playful, and maneuverable. Keel fin setups are ideal for your retro fish and can even be fun in bigger waves. Keel fins offer a skatier feel and longer, more drawn out turns while offering more control and down the line speed than an upright twin fin set in your surfboard.
The sweep, or rake, is how far the front edge of a fin arcs backwards. Rake or sweep angle is a measurement that determines how far back the fin curves in relation to its base. Fins with a small rake (large offset) help propel the board, are very stable and predictable but are not ideal for making sharp fast turns. On the other hand, fins with a large rake angle and a small offset will allow your board to have a tighter turning radius, but are more “squirrelly” and playful.
The base length of the fin is the widest point of the fin, and sits flush with the board once installed. This length can affect how the board will respond to turns. Longer fin bases create trajectories for water to go past - so your surfboard will move faster. If you want to make sharp turns, however, look for a shorter fin base length.
