The 181-foot ferry broke loose from its moorings because of high winds last Friday. It ran aground near Metlakatla.
Marine highway officials say the ferry has damage to its port side keel cooler. The cooler helps lower the temperature of a vessel's mechanical equipment by allowing sea water to pass over tubes that circulate coolant through the engine.
The vessel's port side No. 4 void also has a hole or hairline fracture. Inspections also are planned for the ferry's internal bulkheads and its steering and line shaft alignment.
Officials say work is not scheduled to start until this weekend, at the earliest.
