Our boats have a weight limit of 1820 lbs, which includes passengers, coolers, equipment etc. On average 10-12 people will work on both our Sweetwater and Misty Harbor boats. The age or size of the person on the boat doesn't affect the number of people who can be on the boat. We provide all the adult life vests though we don't have any for children under 50lbs. If you have a child under 50lbs, you must provide your own.
