Maine Boating Laws


All of the following laws and regulations have either been passed by the Maine legislature or adopted by the Commissioner of Inland Fisheries & Wildlife. The following rules/laws are intended to be used only as a guide for boating, and in some cases, the laws and rules have been summarized. For more detailed information on any of the laws/rules contact the Department office In Augusta.

Harbor Pilotage


Portland Harbor, at the western end of Casco Bay, is the most important port on the coast of Maine. The ice-free harbor offers secure anchorage to deep draft vessels in all weather. There is considerable domestic and foreign commerce in petroleum products, paper, wood pulp, scrap metal, coal, salt and containerized goods. It is also the Atlantic terminus pipeline for shipments of crude oil to Montreal and Ontario. In 1998, Portland became the largest port in the Northeast based on throughput tonnages.

A rail system connects the Port to a national network that also reaches into Canada, one of the reasons shippers bypass the crowded and more costly port cities of southern New England and the Mid-Atlantic.
