Tug IMPULSION in the South Docks at Sunderland.
She is still showing the Imperial Tugs logo on her funnel so I guess this was soon after she was bought by North Sea Tugs in 1992.
They bought her in damaged condition after she had sunk off Lowestoft. Don't know whether they ever repaired her before scrapping her in 1998.

ANGLIAN towing IMPULSION into the Wear 27/01/1992.
