The Al Merrick's tri-quad set combines one of the most popular thruster fin set ups with a specially matched pair of quad trailers in the new lightweight AirCore construction. The thruster set combines drive from the raked side fins off the bottom and with exceptional tail release from the smaller trailers. The added quad set is ideal for speed & grip in steeper parts of the wave.

Raked side fins produce exceptional drive & a smaller center fin offers quick release through turns. This fin template was designed by Channel Islands Surfboards founder/shaper Al Merrick, a template developed & refined over his decades of shaping for the worlds best surfers.

This fin’s wide base and raked back shape gives you heaps of drive down the line and hold on rail . The narrower tip and smaller back fin gives you plenty of release off of the top. The PC honeycomb construction creates a positive feeling medium flex pattern, suitable for use in a large range of conditions.
