I was also hoping the elctric motor/battery would be the way to go, but now we are hearing about car fires and boat fires due to the lithium ion batteries. Sounds like we gotta ways to go. Apparently the lithium ion batteries can burn very easily if not handled and charged properly and even then catch fire. CnC, I realize you want to go engineless but if you ever do decide to install an inboard what about finding a good yanmar 1gmd, 10 HP (direct sea water cooled engine). You can burn bio diesel and not have the diesel fume smell (exhasut or fuel). Relatively environmentally friendly, takes up little space (you could have say a 3 gallon fuel tank). When not using my 3gmd I flush with fresh water so hopefully corrosion won't be an issue for a while.
Here is one in Annapolis:
