I used Choptank Soda Blasting (William) 410.822.3990. I have a 246SF World Cat which he did for 300$. I believe he paints as well. He is between Easton and Preston. He did a fine job, only issue w/my boat was I aint putting paint back on her and it turns out the original owner barrier coated the bottom which soda blasting will not remove. So I then had my fiberglass guy sand the epoxy off and then he compounded and buffed the hull. Mine turned out great but the upper part of the hull is slightly more discolored than lower which he said will dimish in time. I gained 0 kts and am saving 0$ after doing all this FWIW.
