Miami Top Charters

Getmyboat and Boatsetter offer yacht rentals with captains, but be aware that prices are high, with a 60' catamaran captained for $431 an hour.

Prices like $2000 total (around $1000/yacht) for 4 hours are unrealistic, and the only place to find 2 yachts for a few hours for $2k in Miami is '1994', implying that it's extremely unlikely or even impossible.
