Shop All FinsOverview - Mod Twin + 1s
The Mod (modern) Twin + 1s are a new design that bridges the gap between thruster and twin fin sets. They feature smaller side fins (than traditional twins) with a larger trailer, thus retaining a similar overall area. The outside fins have a sweep more like a modern thruster set, and when used with the trailer make an easy transition from a regular thruster setup. These fins are ideal if you want to make your board looser, without giving up all the control of your centre fin. If you are used to riding FCS fins, these will feel most similar to the FCS II Rob Machado Twin + Stabiliser Fins. The twins have a 34-degree sweep, base of 126mm, depth of 131mm, area of 12300mm² and a flat foil. The trailer has a 38-degree sweep, base of 94mm, depth of 95mm, area of 7100mm² and a 50/50 foil.
Materials
A blend of fibreglass, carbon, and an ultra-light honeycomb core. The honeycomb core reduces resin content keeping them lightweight. The carbon which wraps the fibreglass increases stiffness at the base of the fin. This gradually reduces to a medium flex through the tip and trailing edge for smooth and controlled turns.
FCS II Compatibility
Pacifica fins are compatible with FCS II finboxes. Our unique rear tab requires that one grub screw is inserted into the rear threaded hole of each finbox. All Pacifica Fins are sold with a fin key and six grub screws. This allows you to leave a set of grub screws in your two favourite boards. There are two benefits to this system. One, your Pacifica fins won't fall out. Two, when inserting and removing your Pacifica Fins you won’t crack the glass in your board around the finbox.
