Its kinda like a 'set-it-and-forget-it' way to own a yacht. You buy the boat, they take care of all the maintenance, insurance & berthing and it can make money for you by being part of a charter fleet. Some yachts even start out owned by the company for a few years before you officially take over. Its a nice option if you want yacht ownership without having to deal with all the day-to-day stuff, especially if you're not planning to be on it all the time
