Macski Plastic Thruster Fin Set | Waveski Fins

Upgrade your waveski with the classic Macski Plastic Thruster Fin Set — a tried-and-tested design that has been a staple of waveski surfing since the 1970s.

Compatible with the standard Macski sliding fin box system, these fins fit 90% of all Macski waveskis ever made, making them one of the most versatile fin options available.

Key Features

• Fits the Macski sliding fin box — fins can be shifted forwards or backwards for tuned performance
• Move fins towards the back for more straight-line control and speed
• Move fins towards the front for improved turning and manoeuvrability
• Each fin is secured with 2 screws (front and back) for a solid, reliable fit
• High-flex plastic construction — safer and more durable than rigid fins
• Ideal for beginner to intermediate surfers

Getting Started

We recommend starting with the fins set in the middle of the fin boxes and adjusting as you develop a feel for your waveski's performance.
