More Than 13 Guests? How Large-Group Yacht Events Work in Miami
If your Miami boating group has more than 13 charter-party guests, a standard bareboat yacht is generally not the right solution. U.S. Coast Guard guidance for a bona fide bareboat charter allows up to 12 passengers plus the charterer, while passenger-for-hire operations above six passengers generally require an inspected vessel with a Certificate of Inspection. Large groups should look at a properly inspected commercial event vessel or, when appropriate, multiple yachts.

Miami has plenty of very large yachts, but yacht length does not override Coast Guard passenger rules. Large groups need to start with the legal operating category of the vessel, then choose the style of event.
Why “the yacht is big enough” is not the answer
A 90-foot yacht may have enough physical space for 25 people, but that does not automatically mean it can legally carry 25 charter guests. Passenger capacity depends on the vessel's operating status and charter structure, not only square footage.
This is one of the most misunderstood parts of booking Miami events on the water.
The 13-guest framework on many private yachts
Coast Guard guidance states that a bona fide bareboat charter may have up to 12 passengers plus the charterer, not including crew. In practical guest-count conversations, that is why many Miami private-yacht options are capped at 13 charter-party guests.
A bareboat charter must also be genuine: the charterer has important rights and responsibilities, including real choice over crew. It is not simply a form used to avoid passenger-vessel rules.
When a commercial inspected vessel is the right solution
For larger events — 20, 30, 50 or even well over 100 guests — the right solution is usually a vessel certificated for commercial passenger service at the required capacity.
These boats may look different from a traditional private motor yacht, but they are designed to host groups legally and operationally. Boating Miami works with event-vessel options for corporate events, celebrations and larger groups.
Option two: multiple private yachts
For some groups, two private yachts departing from the same marina can preserve more of the luxury-yacht feeling. Guests are divided between the vessels while cruising, and the yachts may be able to anchor near each other or raft together when conditions, captain approval and vessel setup allow.
This can be a great social experience, but it needs more planning than simply booking one large boat.
Do not split the guest list at the last minute
Large-group planning should start with headcount, event format and whether everyone truly needs to be together at all times. Then choose the vessel structure.
Trying to force a 20-person event onto a yacht marketed for 13 creates legal, safety and guest-experience problems. Solve the capacity issue first, then work on décor, catering and entertainment.
What to ask when booking a large-group vessel
Ask for the vessel's legal passenger capacity, Coast Guard Certificate of Inspection where applicable, crew plan, boarding marina, catering rules, restroom count, indoor/outdoor capacity, music restrictions and event timing.
For corporate groups, also ask about branding, AV needs, food service and whether the vessel's layout supports the actual agenda — cocktails, presentation, dinner or dancing.
Frequently Asked Questions
Can a 70-foot yacht take 20 guests in Miami?
Not simply because it is 70 feet. Standard private/bareboat arrangements are generally capped at 12 passengers plus the charterer; larger groups need an appropriately certificated commercial vessel or another compliant solution.
Why do so many Miami yachts say 13 guests maximum?
Because U.S. Coast Guard guidance for bona fide bareboat charters allows up to 12 passengers plus the charterer, not including crew.
Can we book two yachts for 20–24 people?
Often yes, depending on availability, marinas and vessel capacities. Guests cruise on separate vessels and can coordinate the experience; any rafting/tie-up is subject to captain approval and conditions.
What is the best option for 30+ guests?
A properly inspected commercial event vessel is usually the simplest and most cohesive solution for a group that needs to stay together.
