PORTAL-FIN heelside edition

Designed and made in Austria, its goal is to improve grip, stability and upwind ability while reducing strain on the body (e.g. knee pain).

Key features and technology

• BoxWing technology (hollow profile): instead of the classic flat shape, the fin has a hollow profile that optimises water flow. Inspired by aviation and motorsport aerodynamics, this shape creates extra lift and drastically improves grip.

• The Topmount mounting system: the fin attaches from below, meaning no visible screws on the top of the board. That gives a cleaner look, prevents snagging and allows better board grip during board-off tricks.

• Materials: made of high-quality TR90 UV polyamide — extremely durable and light (42 g per fin). All metal parts are A4 stainless steel (seawater resistant).

Main benefits for the rider

1. Exceptional grip and control: the increased grip lets you hold the board's edge longer and harder, enabling more explosive pop on jumps and controlled landings.

2. Easier upwind riding: the fin's profile creates extra lift that automatically drives the board upwind, letting you ride at a sharper angle with less effort.

3. Chop absorption: the fin stabilises the board in rough water, making the ride smoother and more comfortable.
