Has anyone here tried getting towed over a lake by an electric toy boat? - how to build a toy boat

I'm trying ways to feed, to find a sea kayak move more of Otago Harbor.
Ship models as a child, I had managed to pull me in a lake in an inflatable radio by an electric motor with an AC-540 Mabuchi with gearbox and reduction of lead-acid battery 12V battery.
