Jim McLay is on the right. 

Jim and his father own the tug Gav & Jim.  Jim is also a geophysist.  This picture was taken at the unloading of the dolomite stone at the Southampton docks.  It was  loaded onto Willy's barge and carried to Chantry Island.  This was the first of many loads taken to the Island mostly by the Peerless, Little Snick and a barge/raft.
