Most rental companies have a maximum of 10-12 passengers per pontoon boat. Please check the restrictions and cancellation policy before booking, as it will state the maximum capacity per rental. Please also be aware that pontoon boats cannot be used as a shuttle. This means that you cannot have 10-12 people on a pontoon boat, drop them off at Crab Island, and pick up another group of 10 people, and take them to Crab Island, as well. This is for your safety. In the case of a pop-up thunderstorm, for example, which is typical in Florida, you will not be able to fit all 20 people on the one rental, putting people in danger. If your group is larger than the 10-12-person maximum, then you will want to consider renting another boat, jet ski, kayak, or paddleboard to accommodate. Another important thing to note is that each person on the boat counts towards your grand total, regardless of age. For example, if there is an infant in your group, even though they don’t take up much space, they would still count towards your grand total.
