Two of my comprehensively re worked Graupner Southamptons at work manoeuvring a steam crane barge at Gresford earlier today.
Each of the tugs has both throttle steer and conventional rudder steering available to the operators.
The lead tug is just undergoing a training phase under it's new owner's control - my tug at the rear is providing stabilty and rescue should things have started heading south. (note to self: pay more attention to the tow rope and less to the photography).
Things didn't so much head south at the front, so much as go quiet.... The new owner had spent his time playing with the his new tugs party trick - pirouetting on the spot - and had run the batteries down - D'OH! Oh well... I only had to dock the lot in reverse, around a jetty, across the wind.... etc etc All in a day's work! :)
Having checked my receipts for the commissioned Southampton + refit, total price not including 4 channel TX = about 230 quid - fun factor = priceless! :)
