The Steamship Authority is updating its staff training program following an internal investigation of last month’s accident in Woods Hole, where the M/V Sankaty came loose from its slip.

With its borrowing limit increased by $50 million in the new state budget, the Steamship Authority now has the financial headroom to add a fourth ship to its growing fleet of identical former oilfield supply vessels, which the ferry line is converting into freight ferries.

Two Steamship Authority ferries, M/V Gay Head and M/V Nantucket, are out of service for the weekend, although the Nantucket is expected to be back in action Sunday night.

The Steamship Authority board voted 3-1 Tuesday to approve the 2024 schedule, which included the controversial 5:30 a.m. freight boat from Woods Hole.

The Steamship Authority’s 5:30 a.m. summer freight boats are once again the target of unhappy Falmouth residents who say the terminal-bound truck traffic destroys their early-morning tranquility.

The M/V Nantucket had a failure of a reduction gear pressure switch Thursday night, according to Steamship general manager Bob Davis.

The boat line board of governors voted last week to postpone the launch a second time, to September, after agreeing earlier this year to move it from March to May.

Soaring costs for steel, a surge in demand at shipyards, a shortage of skilled labor and the Steamship Authority’s own limitations all played their parts in the boat line’s failure to accurately estimate the cost of converting its new oil field vessels for use as freight ferries.

The ferry line announced Wednesday that it was changing the rules for the “blue line” standby on the Vineyard route, moving from a hard cap of 15 vehicles a day to a new rolling 12-vehicle cap.
