I got carried away with the zeros there Graham - Biggest ships I sailed on were the Shell "M" class tankers at a mere 200,000 odd tonnes. They seemed huge at the time, we used bikes to travel up and down the deck and when loaded there was 85 feet below the surface. The later "L" were considerably bigger than that at over 300,000tonnes.
This was the ship I was on running up Cheasapeake Bay - I was away 9 months on that trip, eventually left in Durban to fly home.

SS.
This is the ship, used as an Atlantic weather reporting vessel.

A spent a couple of 6 month stints doing this - The small ship is 70,000 tonnes. We used to meet the larger "M" class tanker in some sheltered area, very often in Lyme Bay, near Torquay, steam alongside and take 70'000 tonnes of oil off her. This was because at 85ft draught when full she unable to get through the channel to Rotterdam, Hamburg etc.
