With two ferries sidelined with mechanical problems, the Steamship Authority will continue to operate through the weekend with just two freight boats, the Katama and the Sankaty, and the SeaStreak.

The passenger-only SeaStreak was put into service after the Woods Hole was pulled out of service late Thursday.

The ferry Martha’s Vineyard is not expected to be back in service until late Monday at the earliest, the boatline said in a press release. The ferry Woods Hole is also expected to be out of service until at least late Sunday, the release said.

The Katama will be making its regularly scheduled runs including an additional run leaving Woods Hole Friday night at 10:45 p.m. and making the return run from Vineyard Haven. The trips are being added to accommodate “trucks with food and other goods whose reservations were cancelled,” the Steamship Authority said.

The Katama will also make an early run on Saturday, departing at 4:30 a.m., and then begin its regularly scheduled trips, starting at 5:30 a.m. in Vineyard Haven.

The Sankaty will continue to take over for the ferry Martha’s Vineyard. All trips for the ferry Woods Hole have been canceled for the weekend.

In an earlier press release today, Robert Davis, Steamship Authority general manager, said an indicator light went off on the console of the Woods Hole as the vessel was loading for the 5 p.m. trip from Vineyard Haven to Woods Hole. Passengers and vehicles were transferred to the freight ferry Katama for the trip to Woods Hole.

The ferry Martha’s Vineyard ran out of power last Saturday evening off East Chop during its 8:30 p.m. run. It had to be towed back to Vineyard Haven, arriving around 1 a.m.

The Martha’s Vineyard was briefly put back into service on Monday but by Wednesday it was pulled out of service again. Both the Woods Hole and the Martha’s Vineyard are now at the Steamship’s maintenance terminal in Fairhaven.
