Ship No 370
As part of the large modernisation programme for the Manchester Ship Canal, an order was placed for the supply of two, latest designed, twin screw diesel tugs.
Onset was the first of the two to be built.
One of the eight tugs to be built by the Henry Robb Company to help make up the post war renewal fleet. She was sold by the Manchester Ship Canal in 1973 and she was to go onto have a few more names.
She became ONSET then AFON WEN of Holyhead Towing Co, both in 1973. In 1976 she was sold on again to Sondora (Panama) and renamed KOCABAS (from 1990 KOCABAS I), she may indeed have been sold on yet again.
She was 154 tons, with a length between perpendiculars (L.B.P.) of 88 feet, with a beam of 23 feet. Powered by a single screw Crossley oil engine I.H.P. 1200
