Refinish 21' boat bottom

Who would be good to call on refinishing a 21’ bay boat bottom. It has rough bottom paint now. Really don’t want bottom paint, especially rough- slows the boat down a lot.

Any ideas on cost?

Give O-Sea-D a call. They just did some gel coat work for me on the bottom of my Bay Reef where the previous owner had oyster rashed her.
