Two large stakes fixed into the ground on both sides of the canal at regular intervals could be used in conjunction with rubber bands stretched between them. The boat could then be propelled forward using the elastic like we used to do with toy planes  |

I've often seen old bicycle inner tubes discarded on towpaths. Perhaps they can be used for catapults.

A magnet on a boat in front tows the boat behind which has a magnet stuck on its nose. Magnetic attraction.

Tie strings to ducks. Throw bread way in front of them. They will pull the boat as they swim forwards to get the bread.

No.
Magnets can be used for certain things like lifting objects but if you want to generate a traction force for pulling a boat you have to put the magnet in the right place to start with and the energy you use to do this will be more than any gain you will achieve.
You could magnetically couple boats together but this would be relatively pointless.

With bigger magnets along the canal to pull the boats forward, The polarity could be changed for travelling the other way Like a maglev train. Would require quite a lot of electricity though. Another option may be to drain the water out, build a solid surface and run wheeled vehicles on it. |

Small children could be put into large hamster wheels which are attached to a prop. It would be good for the aparant obese problem we keep hearing about, or, convicts could spend their sentance in the hamster wheel. Gets them out of the prison and saves a fortune for the government. |

When are CRT gonna erect charging points for electrically propelled boats? Lack of foresight. Lack of electrically propelled boats as well. Chicken and egg situation. |
