Starboard Arma Core Race Ultra Bio Resin Green SUP Fins

FAQ

What is the Starboard Arma Core Race Ultra SUP fin particularly well suited for?

The Starboard Arma Core Race Ultra was developed for high tracking and stability over long distances in shallow water. It is ideal for racing, touring, and training on calm waters such as the North and Baltic Seas.

How big is the fin and will it fit my SUP board?

The fin has a length of 212 mm (8.3 inches) and is mounted using the US box system. This makes it compatible with most modern SUP boards, especially the Starboard Sprint series for shallow-water racing.

What material is the fin made of?

The core of the fin is made of Armacel, which is made from 100 percent recycled plastic bottles (RPET). The whole thing is bonded with a bio-recyclable epoxy resin that is lightweight yet stiff enough for controlled tracking.

Is the fin really sustainable and recyclable?

Yes, the Armacore system enables closed-loop recycling: If the fin is immersed in a solution for 2 to 3 hours, the resin, core, and fiber reinforcement separate. The materials can then be reused or further processed into new bio-products.

For which skill level and what conditions is the fin intended?

The Race Ultra is aimed at ambitious paddlers and racers who value high speed, straight tracking, and minimal changes of paddle side in shallow water. It is less optimally designed for wavy conditions or wave SUPs.

How is the fin mounted and what is included in the delivery?

The fin is delivered without a screw and is inserted into the US box of the board and fixed. The delivery includes the fin and a fin bag for safe storage and transport.

How do I properly care for and transport the fin?

After use, you should rinse the fin with fresh water, let it dry, and store it in the included fin bag protected from sunlight. Regularly check the US box of your board for dirt so that the fin sits clean and free of play.

Does the fin also fit boards of other brands?

As long as your SUP board has a US box fin mount, you can generally install the Starboard Arma Core Race Ultra without any problems. It is designed for lightweight racing and touring boards with a shallow-water focus.
