GEE BEE was built as an RAF Seaplane Tender No 475 by Thornycroft at their Hampton Launch Co. at Platts Eyot on the Thames as yard number 2524 in 1941.

Bought by Mike Mitchell in 1987, from Gilbert Powell who told him that the GEE BEE had been utilised in the Scottish Lochs during the war. The vessel had been kept for many years in a shed at the Port of Blyth, Northumberland.


Mitchell sailed the GEE BEE to the River Tyne, where it was moored at Davy Bank, Wallsend, and restored over a number of years.  The rear cabin was removed and both Perkins 6354 diesel engines were renewed.  She was equipped with navigation and sonar systems. The GEE BEE was used for pleasure, exploring wrecks and sea fishing by Mitchell and his family.  In 1996, GEE BEE moved to St Peters Marina in Newcastle upon Tyne.  She was sold in April 1998 to a man who took the boat to Bridlington.
