Was at the beach recently. Seated on the water for dinner, a large, very nicely decorated boat came by with a wedding party aboard, and another following. They were headed out for a sunset wedding on the water. With your skills of woodworking, I would think you could outfit the first boat with appropriate woodwork, flooring etc. to make it present as the perfect setting for wedding vows or as mentioned, a special occasion. I would think maybe working in conjunction with a wedding planner / consultant or the like would help to give you some great ideas for accesories and decorating. The boat we saw had shiny brass, meticulously clean woodwork and a small crew dressed to the hilt in white "captain's" uniform. Looked like the perfect setting for that perfect moment.
