Renfrew Rose was designed by Ian Nicolson and built in 1984 by MacCrindle Shipbuilding Ltd, Ardrossan.

[2] The two vessels were approaching the end of their working life, and it was estimated that it would cost £2 million to replace them.

After the SPT service ended, Renfrew Rose and her sister, Yoker Swan were purchased by the Arranmore Fast Ferry company for use on the Burtonport to Arranmore island route in County Donegal, Ireland.

[5] The ferry has a front ramp, which is accessed directly from the concrete slipways on both sides of the river.

These give access to the front deck and an enclosed passenger cabin, which provides some shelter during the 2-minute crossing.
