Key Features

NA8 Ships Stability Apparatus

• Apparatus designed to enable students to study ship hydrostatics and stability
• Supply includes a water tank, a floating ship model, a dynamometer and a clinometer
• The model supplied is a 1/70 scale model of a 28,000-tonne general cargo vessel
• It includes a number of transverse watertight bulkheads in representative positions
• The compartments are fitted with individual flooding valves
• The model is constructed of glass reinforced plastic (GRP)
• Models of other ships are available as optional accessories
