I was in a rush to catch some fresh water waves. With most of my quiver in California, I decided to make a Home Depot board. I got a piece of housing insulation 8 feet long and cut it in half. I took the two 8 foot long pieces I glued them together giving them a glued in rocker. Then I cut the outline and sanded a very simple shape. Next I glassed the board in the moonlight and sanded it in the morning. I glassed in a giant 9 inch fin, because it was the only one I had. The board was not the fastest thing in the water, but I always have fun surfing in Lake Michigan.
