In a decision from February 2010, the Maine Supreme Judicial Court upheld a Superior Court judgment granting damages in the amount of $4.9 million against Central Maine Power Company to a man who was severely injured when the mast of a sailboat he was moving in a boatyard came in contact with a power line.

The court held that CMP was negligent, because it had strung its lines too low knowing that they were within the area of a known boatyard operation, even though the power lines were strung over a public road, Rt. 166 in the Town of Penobscot.  The case turned on an interpretation of a Public Utilities Commission rule requiring a 45.5 foot height in an area intended to be used by the public for launching and rigging sailboats.
