True Ames Mandala Delta-V

These fins are designed for twin-fin setups, specifically boards that prioritize speed and maneuverability. They perform best on fish-style boards or performance twins where you want to maintain a loose, responsive feel while still having enough hold for tighter turns.

The Mandala Delta-V Twin fins are built for the Futures fin system. Before purchasing, verify that your surfboard has Futures fin boxes, as they are not compatible with FCS or other fin box systems.

The Delta-V template is engineered to balance speed with control. While many twin fins can feel loose or slippery, this design optimizes water flow to provide a more reliable hold during carves and transitions, making it a versatile choice for a wider range of wave conditions.

Not at all. The design is intended to keep the board feeling lively and responsive. They offer enough drive to generate speed in weaker waves, but they are refined enough to handle snappy, quick maneuvers without feeling locked in.

Yes, you will need a standard Futures fin key to secure the fins into the boxes. Since these are removable, the key allows you to easily swap them out or adjust their position if your board setup allows for it.
