Dave Rastovich at Cloudbreak on a 6'3'' George Greenough shaped Edgeboard

Single fin, high aspect fin foil, GG still tinkering.
Thruster proportions, with a unique Greenough touch.

GG's edge spoons needed VERY thick fins to allow the edges to flow across the water without catching.

His formula was a 5.5 to 1 aspect ratio ... meaning a fin with a 5 inch wide base was almost 15/16" inch thick. Also, the thickest point of his fins was well forward, with a blunt leading edge. The back half of the foil was almost flat.

Hopefully, these edge boards are being ridden with the right fin.
