Ofcourse! Most motor yachts are aluminum construction ,they would not go very far without antifouling coatings . Look for a high quality non copper based coating such as Pettit Ultima ECO. Also available is vivid ,I believe that is Pettit too. Doesn't hurt and you should prep the hull with barrier coat and primers.

To re-fiberglass a boat, first, remove any damaged fiberglass and clean the area thoroughly. Then, apply a layer of fiberglass cloth over the affected area, ensuring it overlaps the edges for better adhesion.

Once cured, sand the surface smooth and apply additional layers as needed for strength and finish.
