One thing that is always overlooked by many that think they can make a quick buck doing a charter is the boat it's self must documented as a commercial vessel and equipped as a commercial passenger vessel. Please see CFR 46 for the requirements. Under 6 passengers is a OUPV, over 6 passengers the vessel needs to be inspected and have a valid COI from the CG and the Capt. must have a Masters license.One other point... if you're receiving compensation for the use of your boat, you may be considered that the boat is being chartered. Charter boats require commercial insurance generally, and also require a USCG licensed captain involved.
