Here is the centreboard being coated in one layer of 400gm Kevlar and two layers of 200gm glass. I want lots of torsional rigitiy incase I hit something. I had to sharpen my scissors to cut kevlar. One edge has fine serration's and the other is straight. Made a big difference to being able to cut kevlar. I used two layers of glass as it is easier to sand the glass than kevlar. Kevlar just goes all fuzzy.
