We used Dream Yacht Charters in May, 2016. The boat was only a year old, but was maintained very poorly. The boat stunk so bad, I had to sleep outside most of the trip. The generator stalled out every hour of so. Had a mechanic out to look at it, but nothing he could do, we just had to keep re-starting. Doesn't work if your trying to sleep with the a/c on at night. One cabin a/c unit didn't work at all, one cabin had no lights, one cabin's toilet leaked
Many other small broken things that you would not expect on a new boat.
We have chartered from Conch many times, although their boats are older, much better maintained then DYC.
