A modified Thunder Tiger fishing boat. The jib of the crane is made from a coat-hanger and its boiler is a small plastic bottle. The diver is modelled in plasticine and his air supply is provided by a battery-powered aquarium puffer. The diver now has a life-line as one of his brothers was lost in the Setley deeps. [Web-master's comment: any one working in standard diving gear without a safety line is asking to be lost; possibly we might have to incorporate a paragraph in the club rules.]
