Marine Atlantic on Tuesday pulled one of its oldest ferries from service for at least two weeks, as repairs continue on the MV Joseph and Clara Smallwood's rudder.

The Crown corporation has stopped accepting new reservations as its reduced fleet has been trying to deal with the loss of the Smallwood.

In addition to the Smallwood, Marine Atlantic has another ferry, the Atlantic Vision, off the water for scheduled maintenance.

The two ferries sailing between North Sydney, N.S., and Port aux Basques, N.L. — the Caribou and the Leif Ericson — will continue working on a load-and-go basis, Marine Atlantic vice-president Don Barnes said in a statement.

"While capacity on the Gulf crossing will be temporarily reduced, all existing reservations will be accommodated," Marine Atlantic said in a statement.

The company said its reservation system is expected to re-open "in the coming days."

The 21-year-old Smallwood, which can carry a maximum of 370 cars or 77 tractor-trailers, has had other recent problems, including being pulled from service in August for mechanical problems. It is due to be retired soon as part of Marine Atlantic's replacement program.
