JPI Single Fin
In 1976 Jack is shaping boards at Shane’s factory at Brookvale when a guy named Jim Pollard comes in with a revolutionary new bottom design - soft full-length channels that curve down the board parallel to the rail. They were coined the “Fluid Foils” and from about 1976 to 1981 Jack shaped these boards alongside Jim and a bunch of other production shapers at Shane’s. During their peak popularity in the late 70’s Jack estimates he was shaping about 10 - 15 channel-bottom boards himself each week.
The current version of these boards are inspired by Jim Pollard’s original concept with a few modern tweaks.
The channels begin 12 inches from the nose, starting soft and running on a curved path parallel to the rail line before exiting out through subtle flyers in the tail. They work by collecting and compressing water through the front and then releasing it through the tail which creates a fast and more lively feel when compared to a standard single fin.
Jack has shaped these boards in a variety of styles - from more performance/tighter outlines more cruisey wider outlines.
