Overview

Harley Ingleby's Mid 6 and Moe midlength models have become some of the most popular in this category. This is Harley's preferred fin set that's spec'd to work on longer boards and encourages a more progressive style of mid-length surfing. HI also rides this set on in other hybrid shapes. The HI Mid set can be applied to any mid-length with a Tri-Quad setup.

The set comprises the Reactor Large thruster template and the Performer Large quad rear fins. As a thruster this pivotal set encourages tighter radius turns on these longer boards due to the upright nature of the fins. As a quad set, it will feel fast, smooth and predictable while encouraging a more drawn-out term. Both configurations are designed to offer a feeling of control, with the freedom to surf radically on a mid-length.

Harley's Mid Tri-Quad set has been constructed in our PC AirCore technology, which is stiff enough to handle the extra torque of these longer boards while offering a fast and responsive feel through turns.

Performance Core + AirCore

Fins with AirCore Technology feature a pressed polyurethane foam core that mimics the geometric foil of the fin.

AirCore technology reduces the amount of fiberglass required in the RTM moulding process making it much lighter while allowing total manipulation of the flex.
