The other day I mentioned the Oru Kayak with Electrafin, but I wanted to point out that this is not the only product that Current Drives produces. The same device can attach to SUPs (Stand Up Paddleboards), and they have their own SUPs and inflatable SUPs with integrated electric drives.
I need to try a SUP someday… not sure my balance is that good, but looks like fun 🙂
Oru Kayak has had some really neat, Coroplast kayaks for a while now. They are fold up into an easily transportable box that you can sling on your bike or whatever, then assemble when you are ready for the water.
