The ferry Nantucket was back in service Friday morning after a week of mechanical breakdowns and shuffling for the Steamship Authority on the Vineyard route.

Service on the Nantucket was set to resume with the 9:30 trip from Woods Hole, SSA spokesman Sean Driscoll said.

The Nantucket went out on Thursday causing cancellations and service disruptions throughout the day, while a generator issue was being investigated.

Two days earlier, the freight ferry Katama was called into service from Fairhaven Tuesday after the freight ferry Governor went out with unspecified mechancial problems. The ferry had stalled while docking in Woods Hole Tuesday morning, Mr. Driscoll said.

By Thursday the Governor was back in service but the Nantucket was out. The Katama, which had been brought over from Fairhaven to run in place of the Governor, was still running, as routes were shuffled and trip cancellations piled up.

At the end of the day Thursday, the Steamship Authority issued a statement about service changes that would run from Thursday night through Friday morning. On Friday morning the boat line advised travelers to check the SSA website for up-to-date information.

“We thank our customers for their patience and understanding,” the statement issued Thursday said.

Tuesday was also opening day for the Oak Bluffs summer terminal for the 2022 season. Mr. Driscoll said all went smoothly.

“It’s always exciting when Oak Bluffs opens up,” he said. “It was a good day for it. Nice clear, sunny day.”

The rest of the week did not go as smoothly.
