How Many People Fit on a Charleston Party Boat?
Updated September 27, 2026. 5 minute read.
Capacity is the first thing to sort out, because it decides which boats you can consider at all. Here's how it works for charters around Charleston.
The six-passenger line
Many small charter boats are run under a captain's license that allows up to six paying passengers. You'll sometimes hear these called six-pack charters. They're common, flexible and usually the most affordable option for small groups.
Inspected vessels for bigger groups
To carry more than six paying passengers, a boat generally needs to be inspected by the Coast Guard. An inspected vessel has a Certificate of Inspection that lists its maximum number of passengers. That number is a hard limit.
Legal capacity vs comfortable capacity
A boat certified for 30 passengers isn't always comfortable with 30 guests, a cooler for each and a birthday cake. If your group has a lot of gear or wants room to move and dance, choose a boat with some space to spare.
How to count your group
When you request a boat, count everyone who will be on board:
- Every adult and child, including infants
- Anyone joining for only part of the weekend
- Photographers or other vendors who will ride along
Typical ranges by boat type
As a rough guide: small center consoles and pontoons on six-passenger charters, mid-size inspected pontoons and catamarans for groups in the teens and twenties, and larger party barges and yachts for 30 or more. Every vessel is different, so the operator's stated capacity is what counts.
Quick answers
Can we add one more person to a six-passenger boat?
No. The limit applies to the captain's license and the boat, so a seventh passenger means a different boat.
Do children count toward capacity?
Yes. Everyone on board counts, including infants.
Policies, prices and conditions vary by operator and change over time. Confirm details with your charter operator before booking.
