The Rusty Moby Fish Quad ACT was first shaped in 2005 as an experiment with a 4-fin setup – and it quickly became one of Rusty's most reliable and versatile designs. Despite its generous size, it performs impressively well not just in small, fun waves but also in solid overhead surf. With a fuller outline and ample surface area, it delivers excellent paddle power, speed and glide.

The relaxed entry rocker helps with paddling and catching waves, while the more progressive exit rocker toward the tail allows the board to engage the wave face and perform clean, controlled turns. The rails are full yet angular, with a lower apex that adds lift and keeps the board stable yet responsive.

Ideal as a daily driver for surfers who want the paddle ease and glide of a longboard, but with more maneuverability and reduced length.

The ACT construction (Advanced Composite Technology) uses pre-impregnated fiberglass cloth in a precisely controlled lamination process, eliminating excess resin and dead weight. The result is a strong, lightweight board with enhanced flex and responsiveness.
