Many thanks for posting the old girl, had some laughs on her back in the late seventies. Although you wouldn't think it she also had a bow thrust.
Dave have a look at the posting on the Wimpey Sealab in the new members area, bit more detail on her history.
Once again many thanks Steve
I fitted a talkback system and I think an extra VHF in Fleetwood late 70's
early 80's, she was in for about a week I think, being made ready for the
survey/drilling work, I think Robertsons of Fleetwood fitted extra winches.
