One fin setup doesn't fit every condition, and this package gives you the flexibility to run two different configurations from a single kit.

The SIC Three Four XL + Mahi 9.0" bundles a 9" Mahi centre fin with the Three Four XL side bite set, letting you switch between a traditional single fin setup for smooth cruising and long-distance glide, or drop in the side bites for a thruster configuration when the waves are calling. Both options live in the same bag, so you're ready for whatever the day brings without carrying duplicate gear.

The glass and carbon composite construction keeps the overall weight down while delivering the stiffness and responsiveness that performance surf SUP demands. The Mahi centre fin's dolphin template is a proven shape for tracking and stability, and it pairs naturally with the asymmetrical rear geometry of the Three Four XL when running the full thruster setup.

A practical choice for paddlers who split their time between flatwater touring and surf sessions, and a smart way to get more out of a board that can handle both.
