Concept Ideation

The Triton Pedal Powered Boat World Record project started in October 2015 almost by accident. Julian Fletcher was asked to think about a team building event for a new combined engineering team at work and when he got home his daughter’s Guinness World Record book fell open at the page…

Feasibility Study

We realised that the full sized prototype would take a lot of time to build and also we had sponsors about to make significant contributions, so the last thing we wanted to do was to have made a really silly mistake somewhere along the line in our calculations. For this reason we made a…

Prototype boat details: Hulls: 10m long, 112mm wide, 600mm deep with tapered tips, 500mm x 300mm rudder at the end of each hull connected to the tiller via rigid cable. Hull construction is 100mm thick Kingspan insulation foam with 100mm x 50mm timber beams around edges and 5.5mm plywood panels on…

    So: testing at Carsington: The prototype was built to show that the calculations we were using were the same as the real thing. By this we mean that we did some sums to say what the boat drag would be, how the propeller would behave and hence how fast the boat would go in the water. If these sums were right, we could then change the numbers in them and work out how to design a boat to break the record. Thankfully the numbers did come out about right – we did loads of testing – different pedal speeds and boat directions, different numbers of crew (hence different weight in the water) and direct measurements of the drag with the lovely folks at Carsington pulling the boat along with their rescue boat. Smashing science in action.
    The overall result was that we knew how light and fast the Record Attempt Boat would be. It will need to be an exceptional piece of engineering.
