The ferry Woods Hole was sidelined Saturday after the Steamship Authority discovered a leak in the vessel’s coolant system last week, spokesman Sean Driscoll confirmed Monday.

The ferry Governor is running in her place, Mr. Driscoll said. He said the issue has caused no changes in service on the boatline.

“We haven’t missed any trips or made any changes to the schedule,” he said.

The SSA is currently working on the leak found in the Woods Hole’s keel cooler, but Mr. Driscoll said the timeline for her return is unclear.
