It is unsafe to venture out onto Maine's coastal waters without having the necessary equipment and experience. This is true of kayaking, canoeing, sailing or any other kind of boating. The water is cold and hypothermia can set in in a short amount of time. Dense fog often rolls in very quickly as well as the occasional storm. If you are determined to go out on your own to do so without every single passenger wearing a PFD and/or without having a compass and knowing how to use it and/or without understanding how to navigate safely around other boats and water hazards is not only foolish but could result in serious fines from the Coast Guard or a Marine Patrol officer. There are numerous companies on Mount Desert Island and else where that offer guided sea kayak, sailing, and power boat tours.
