Peter has an article up about his Electric Quick Canoe.
A simple cargo canoe that builds in a couple of weekends
It turned out quite well!
I can see advantages to the standard seats in terms of keeping the crew low in the boat and the structure more rigid. And if you want moulded seats finding ones that will fit on the designed seats.
The ones Peter used don’t support and stiffen the sides of the boat. Probably recommend two spreader bars about 3ft (900mm) or more apart either side of the middle of the boat if using this style of seat.
He also shows some nice mods to move the throttle arrangement of the electric outboard / electric trolling motor.
But it looks really good doesn’t it! And it is about the fastest build cargo canoe there is.
