Surfboard Fin Systems
Fixed Fins
Fins are glassed into the board which means that they are lighter and stronger, thus becoming a popular choice for professional surfers. The drawback to glassed on fins is that you are unable to remove the fins from your board (can be a problem when travelling), also if you snap off or break a fin, you will have to have a new fin reset, which can be time consuming and expensive.
Removable Fins
Blurb from RedXFins.com: The fin system that breaks new ground for board makers worldwide. The Red X fin system provides two qualities so far unavailable in any industry fin use/replace method. Rock Solid Lock... a simple screw in technology that uses stainless steel fittings and a single blade screwdriver. Shiftability... 3/4 of an inch of play in the movement of the fins.

The FTP1 is available in three types of construction, black composite, four colors of fiber glass, and also RTM Honeycomb. We're extremely pleased with the Futures models, especially the fiber glass and RTM models. The Futures box system offers a firm connection to the board with the base of the entire fin imbedded in the board. There is no gap between the fin and the deck resulting in more drive and a positive feel, especially for larger riders.
