Maui Ultra Fins - engineered fins for windsurfing and SUP

Maui Ultra Fins is a specialist fin brand established in 2007, focused on windsurfing, SUP, kite and surf applications. The brand is built around advanced profile design, fluid dynamics and testing in real windsurfing conditions. Its approach is clear: create a windsurf fin that gives control, speed and confidence across freeride, wave, speed, weed and shallow-water sessions.

What makes Maui Ultra Fins stand out?

• Engineering-led profiles: Maui Ultra uses aerodynamic and fluid-dynamics principles to optimise fin profile, lift and control.
• Computer-based development: the brand history states that hundreds of profiles were calculated before creating a new fin design.
• CNC-made G-10 prototypes: early prototypes were produced on Maui and tested with feedback from professional and amateur riders.
• Delta concept: inspired by Delta wings, these fins use short span, high rake, large area and thin stiff profiles for shallow, weedy and speed sailing.
• Wide box compatibility: selected models are available for Power Box, Tuttle Box, Deep Tuttle Box, US Box and Slot Box systems.
• Practical accessories: Maui Ultra Fixed Harness Lines use pre-stretched inner polyester rope, abrasion-resistant PU tubing and non-slip boom contact material.

Who is Maui Ultra Fins for?

Maui Ultra Fins is for windsurfers and SUP riders who want to tune their board with the right fin for the spot and discipline. A freeride windsurf fin such as Ultra Ride suits riders looking for early planing, control when overpowered and strong upwind performance.

Wave riders can look at a wave windsurf fin such as Ultra Wave, X-Wave or twin and multi-fin options for speed, agility and control in varied conditions. For shallow water and weed-heavy spots, the weed fin windsurf range includes Delta, X-Weed and other weed-focused shapes.

Advanced sailors and speed riders can use Maui Ultra’s speed and slalom designs to reduce spinout and improve drive, while SUP users can choose a SUP fin for their board setup.
