Boat Ownership provides marine-enthusiasts with ownership of shares in yachts of all sizes and uses. Some programs sell actual equity in the watercraft and others sell "membership," where the members' dues provide access to the boats, but no ownership. Fractional yacht companies sell shares/membership in small motor boats, sailboats, mid-range yachts all the way to the megayachts for day-use, multi year contracts, or charter-like arrangements.
