Tugs FLYING WITCH, FLYING DOLPHIN and FLYING BUZZARD tow ore carrier MORAR downriver to sea

Tugs FLYING WITCH, FLYING DOLPHIN and FLYING BUZZARD were towing the ore carrier MORAR as she made her way downriver past Bowling to sea.
FLYING WITCH and FLYING DOLPHIN were towing at MORAR's bow and FLYING BUZZARD was attached to the stern, probably for steerage purposes to negotiate the bends in the River channel.

MORAR was built with an experimental gas turbine propulsion system instead of the usual marine diesel engine. This novel turbine system proved extremely unreliable in use, and MORAR suffered many engine problems and breakdowns.
Perhaps this unreliability was the reason that, in todays instance, for safety and security, she was being towed down the narrow winding river channel from Glasgow to the sea, instead of making the passage under her own power.
