Visit the Denny Ship Model Experiment Tank, Dumbarton, to discover how William Denny and Brothers’ innovative and experimental approach to shipbuilding made waves in the shipbuilding industry from the 1800s to 1963.

See the world’s first commercial ship model experiment tank, the length of a football pitch, and see the ship model carriage running.

Enter the world of the Victorian ship designer, in William Denny’s drawing office, and find out how to design your own ship. Learn about Denny Brothers, builders of the famous Cutty-Sark and inventors of the Denny helicopter, Denny hovercraft and Denny-Brown stabilisers.

Discover ship models, photographs and historic objects in the Propeller shop. Experience the working environment of the traditional model makers, clay moulders and carpenters in 1882. Test different hull designs in our mini experiment tank with its own wave making machine.

Try your hand at smoothing and carving a real wax hull model.
