They do try very hard as a group and manage to deliver a huge majority of the time. We had a boat there for 9 years which averaged 30 plus weeks of charter. They kept her in terrific shape and in spite of a myriad of systems to keep operating in a 24 hour turn around (along with some charterers not being honest about anything not working or missing) had exceedingly few problems. We let some friends use her in the last year we owned her whom we had started on their own BVI addiction with a "free trip" with a captain from TMM, in between they had passed all ASA courses and chartered from TMM about a dozen times...they were amazed that our boat was just as comfortable and dependable as it was in the first year of its life. That is very hard to accomplish, impossible without a great organization concentrating on their product more than advertising to insure their success.
