If your looking for the ultimate full body workout just sand the bottom of your boat to the gel coat! It’s a humbling job which hopefully will pay off for many more years of sailing adventures! I knew it had to be done given our survey and I’m happy it’s a one time job at least for this vessel! After the bottom is stripped to the gel coat I’ll put three coats of epoxy barrier coats and a few coats of anti fouling paint. Well it’s back to grinding more to come.
