Here is a bit of history, but please don't take anything as precise facts as this is going back a lot of years. BUC was the original MLS for yachts. It primarily worked for brokers by providing a list of boats and BUC would fax you the information requested. When YachtWorld came to be, brokers copied their BUC specs and put them on YW. BUC said that when a broker subscribed to BUC, they agreed that BUC owned the information which meant brokers no longer had control, nor the right to put that information on YW. FYBA (Fl. Yacht Brokers Assoc). sued BUC and they lost. So FYBA started YATCO. It is rare even today to find a client who knows about YATCO. YW has been sold at least once and I think more. I don't know of a broker that likes YW but without question, it is the resource clients use, whether by choice or not. Although YATCO is improving over time, until someone comes up with the resources and marketing ability to offer competition, YW is the significant multiple listing service.
