What is the crew like, and how much do we see of them?
Professional, discreet and as present or invisible as you want. On a crewed charter the crew live aboard but stay out of the guest areas unless they are working.
A catamaran typically carries a captain and a chef, sometimes a single couple doing both. Larger motor yachts carry four to ten crew with defined roles. They have their own quarters and their own routine. Tell them on day one how you want it: some parties want the crew at the table telling stories, others want to be left alone. Both are normal and neither will surprise them.
Tell us your dates and party size and we will come back with a shortlist of real, available yachts.
