View topic - Two canoes as platform pontoons for hauling lumber/materials

That comment from Splake got me thinking about folks using two canoes (close to equal in depth and length) with a platform across the top and a motor to haul materials. I remember as a child seeing people doing that with a lashed pair of Grummans, hauling cabin building materials out to islands they had leased on the Susquehanna. Repeatedly, it took a bunch of weekends to haul it out and build it.

Plenty of double canoes rigged that way go down the Green River, albeit sans motor. (Also no thanks, while it seems to work well I’m not going down the Green with 3 companions in close proximity unless they are all mutes)

Anyone have any experience with double canoe platforms as motorized material haulers? Platform dimensions and distance, crossbar attachment method, capacity?

I've only rafted canoes for pleasure. Here's a good vid that makes work look pleasurable.

I have lashed two canoes together many times. Watch your weight and realize they are top heavy. Even in a light chop the hulls will tend to plunge through waves instead of going up and over. Lash the boats around 7 feet apart.

I have often thought of lashing three canoes together and pushing them on a big lake with a small outboard. We would build a deck, have a mast, and room to move around. Floating Man. My choice would be the Upper Columbia R behind Grand Coulee Dam. 186 miles.
