Calculating the boat speed thought the water

[mjcoon]

Just had a thought. If one had an old mechanical stopwatch, then the dial could be re-calibrated to a fixed distance on the boat.

Or, of course, a smartphone app could be built to simulate that. What's the betting there is already one of those?

Well spotted! Miffed that the Android version is £1.99 (vs. £1.49)...

Exactly what kind of engineer are you?

One that does things with very, very long wires, electricity and the movement of stuff down the very long wires.
