A petition signed by 50 Falmouth residents has forced the Steamship Authority to schedule a public hearing Monday afternoon on its proposed summer 2020 operating schedule, which includes a 5:30 a.m. freight boat from Woods Hole to Martha’s Vineyard.

“We object to the scheduling of freight from Woods Hole prior to 6 a.m. due to the sleep deprivation caused by the early morning noise impact of Steamship Authority-related freight trucks on Falmouth and Woods Hole residents,” the petition reads.

Under the state enabling act that brought the SSA into existence in 1960, the boat line is required to publish its proposed operating schedules in advance of approving them and to hold a hearing when at least 50 port town residents sign up to request it.

People living near the Woods Hole terminal and along Woods Hole Road have long complained about ferry-related truck traffic past their homes.

But while these Falmouth residents oppose the early-morning freight trip, selectmen in at least two Vineyard towns are lining up against the opposition. At recent meetings, Tisbury and Aquinnah selectmen both agreed to write the Steamship Authority in support of retaining the 5:30 a.m. Vineyard-bound freight boat next year.

Monday’s hearing on the proposed summer, 2020 ferry schedule begins at 4 p.m. in the auditorium at Falmouth High School. The hearing notice, the petition and the proposed schedule are posted on the Steamship Authority website.

Boat line governors are expected to vote on the proposed schedule at their next regular meeting, set for Sept. 24 at the Nantucket Whaling Museum.
