TMM has been great in securing bookings. Almost too good. We have to pick our times a year in advance or we can get shut out. We are booked nearly solid throught May and already have a number of Fall bookings. I think a lot has to do with the bost you pick. We have stuck with two cabin models because they aren't suited to be party boats and therefore get less wear and tear. They are also well suited to sailing with a two person crew.
It is also easier to sell a 40' mono or a 36' cat than a 50' sloop with four cabins.
