I decided to make a gravity powered boat for no particularly good reason. It ended up too big for my bath and the paddle was not very effective.

The 'paddle wheel' I used came from a solar vent featured in this video https://youtu.be/vaE9f0WObwg?list=PLA5a2xPRSrB1GrgALJEle2lVqOrR1sX6V
I don't think it was very successful and if I wanted this boat to go better I would make my own paddle wheel next time. Probably something like the ones in these boats.

A bigger paddle would seem to be a better option. It would slow the descent of the weight due to the increased resistance in the water and would travel further. Obviously there would be an optimum paddle size for the weight used to get the maximum distance or speed depending on what the target was. I think we can call this project just one of those 'proof of concept' ideas.
