If you work for for someone else you'll make $20/hour, no benefits. To have a shot at making money in the charter business you need to own the business...and the business needs to be a success. Even in a temperate clime, that is a long shot. If you are doing a 6pack daytrip business, you'll need to pay for the boat, the dock space, business costs, and a mate's salary before you make a buck.
Having a scheme where you can count on a consistent 70-80% occupancy level on an inspected vessel, would give you a chance at making a iving, but finding that level of business is challenging.Cheers Sailing Charters on Hilton Head Island
