Yes. The United States Coast Guard counts every living, breathing person on the boat as a passenger on the vessel. We are legally only allowed to carry a certain number of total passengers (plus captain and crew), so please make sure to purchase a seat for each person in your group. Additionally, if the total weight of your group exceeds 250lbs per person (for example a family of 4 that weighs more than 1000lbs), please let us know when booking so that we can block off additional seats so as not to exceed the weight limit on the boat.
