Narrative:

While sitting on a barge with a helipad at ground idle, a 32 ft fishing vessel motored from behind to my right under my rotor disk. The captain of the fishing vessel never looked at me or the rotor disk. The blade struck the aluminum poles used for the antennas (5). The blades were damaged. An a&P ok'ed the ferry to akn where the 2 main rotors were changed. The incident occurred because of the fishing vessel captain being tired and in a rush. There were no injuries. The pilot had no accidents or incidents in his 4000 hours of flying.
