Details of the prototype. The Timrix was constructed as the “Ellie” by Cochranes of Selby. Whilst still on the slips she passed ownership to Metcalf Motor Coatsterd Ltd and was completed and launched as the Nellie M in March 1972. The Nellis M was designed as a bulk cargo and container carrier and was launched by the elder daughter of the founder of the firm. She was then sold to an Irish company possibly Arklow and was sunk by I.R.A. action in the late 1970s. The ship was raised and refurbished. during her spell in the shipyard she was lengthened by approx 7 metres and changed into a two hatch vessel. A later refit in the early 90s saw the number two hatch raised. She was sold out of the Rix Company service in 1998 and was replaced with a more modern ship which is a sister to three others in the Rix fleet. The Timrix was powered by a 1160 bhp Allen type 8pbcs 12-D engine propulsion engine which gave a one way speed on trials of 16 knots and a mean speed of 12.9 knots. The ship has a dead-weight of 1160 tons. |
