I assume the tug is in Halifax to tow out the small dump scows SA2 and SA3 that Dexter was using in at Pier 6. They are owned by Indian Head Towing of Port Hastings, NS. Scotia Diver probably towed them to Halifax as well, but I missed that. The wild weather for the last few days has no doubt resulted in a postponement of any departure.
The new owner has done a lot of work on the tug, but this is how she appeared in 1999.
