I don,t know how possible this is ,BUT what about a series on electro magnet arranged either in the water or along the bank .
? Then by using a series of switches to activate the magnets the boat would be drawn along (a bit like a linear motor)
I am sure that some electroniclly minded person could suggest a circuit that controlled the magnets to produce the "energy" to faciltate the movemnt that you require .
Its just an idea really but some one might be able to suggest a method of doing this
With very best regards Bernard (berjay)
