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.
