G Square Fin Layout Tool

Greenlight created the Gsquare as a compliment to the Versa-Square to serve the shapers out there who use the 'old school' method of fin layouts.

The Gsquare quickly and accurately measures the position of the trailing edge of the fin (shaper's dot) from the stringer, as opposed to measuring from the rail.

Toe-in angle is established very quickly by subtracting the desired toe-in from the shaper's dot position. Watch the video below to see how it works.

The G square also measures Nose, Midpoint, and Tail widths and is very helpful for "McKee" style fin placements.
