Welsh Towing Company

Growth Continues

Holyhead Towing has added another boat to its diverse fleet of tugs and work- boats. Like most of the vessels in the fleet, the Afon Alaw is named after a river on the Island of Anglesey where the company's home port is located. (Afon is Welsh for river.)

This is the third vessel built for the company by Hepworth Shipyard of

Paull, Kingston Upon Hull and will be the most powerful in a fleet that includes multicats, survey boats, fast crew boats and a large split hopper barge. The 83.6 x 29.5-ft. tug has a molded depth of 11.8 ft., which allows a shallow 7.8 ft. work- ing draft, this is important as a major focus of Holyhead Towing's work is dredging and marine civil engineering support in shallow water. The company's work also includes pipelay support and cable work throughout North West

Europe and the Caspian Sea. ffiQOiNC rnmmi iNirQTiriNC nnKiiic LUIiiIUIIILHi IUIi J
