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.
Hopefully there's some footage out there...Cool post Kirk. It's good to see some OG submissions.
