Scale: 1:64. A simple but nevertheless ingenious working model that depicts the method of discharging aggregate. A discreet cutaway section, which has been ‘glazed’ with a thin transparent film, in the starboard quarter of the hull, shows how the process is performed, which is electrically operated when the model is connected to a mains supply. The four forward holds have been shown empty and the one furthest forward has its bottom doors open, as though the ship has just discharged its contents.

The ‘St Bees’ (1968) was a motor-driven, self-propelled hopper barge, built by Richards Ltd., of Lowestoft, for the Department of the Environment, from whom the Museum acquired this model. It had a hopper capacity of 1150 cubic meters and a load displacement of 2700 tons. We can see from the model that the ‘St Bees’ was surprisingly streamlined with fine lines, particularly around the bridge area. In fact the funnel detailing would not have looked out of place on a cruise ship of the period.
