Deep Sea Research Vessel (DSRV) - Built and presented by Dave Ryder of St. Helens & District Model Boat Club.The model is a DSRV built on a scale 1:10 approx. Construction is a glass fibre outer hull with a perspex tube inner hull.Operation; Water is pumped into the inner hull under pressure and the submersible sinks. To surface the water is let out of the hull by a valve and the pressure formed by pumping the water in forces the water out and the vessel comes back to the surface.This model is powered by an electric moto contained within a watertight compartment in the inner hull.
