History

The '42' was originally built as one of the RNLI Medina project boats in1984 as a trial craft. MRI rediscovered her in 2000, lying in Liverpool and bought her. She was totally stripped, lengthened and rebuilt by Amble Boatyard to modern requirements and specification and re launched in October 2001.

Mr David Stogdon MBE was the boat designer and performed the naming ceremony on behalf of MRI on 31st October 2001. MRI 42 went to her first SAR call at Stonehaven on November 18th 2001.
