For 20 people you need a bigger boat than most Miami charters: a party pontoon, a party boat, a catamaran or a large yacht. Fewer operators have them, and each boat’s guest limit matters more than the company’s. This page lists private boats for 20 or more, what they publish, and the cost per person.

Tips
3 operators in our directory (Oct 2026) publish a 4-hour price for a boat whose own guest maximum is 20 or more: $1,300–$3,600, median $2,000. Per person = price ÷ 20, our math: $65–$180. 4 more publish a price for a boat this size for another length (listed, not in the range). 4 list boats this big without a published price for them: ask for a 20-person quote. Ask whether gratuity, fuel and fees are included.
12 operators in our directory (Oct 2026) list a boat for 20 or more guests, all in the table on this page. 3 of them publish a 4-hour price for that boat.
A party pontoon is usually the lowest price per hour; a catamaran gives the most stable deck space; a party boat is built for music.
It depends on the operator. Ask whether the number on its site counts guests only.
Many operators allow it, but rules differ. Ask before you book, and ask whether there is a cooler and ice.
