Fins

SUP fins are one of the most impactful and overlooked upgrades you can make — the right fin setup transforms how your board tracks, turns, and feels underfoot.

A single large centre fin gives maximum straight-line tracking for flat water touring and fitness paddling. A thruster setup with a centre fin and two side fins increases manoeuvrability for surfing and mixed-condition paddling. Fin size, template, and material (plastic, fibreglass, or carbon) all affect performance. US Box fins are the most common fitment across inflatable and hard boards, offering a wide aftermarket selection.

• US Box fins: the most widely compatible fitment across brands and board types
• Single fin: maximum tracking efficiency for flat water touring and racing
• Thruster and 2+1 setups: improved manoeuvrability for wave and mixed-use paddling

Starboard and Naish board-matched fins are available alongside a broad aftermarket selection for upgraders.
