Displacement...
I have never measured it. One of the last parts of the build that is still on the bench is more of a hopper instead of the flat top barges. Even it at this point is still using a solid 2x6 as a base so I am wasting a LOT of the displacement potential.
I don't remember exactly now without measuring them but one barge is about 5x18". If I could convert that to gallons and say sink it halfway for some freeboard margin I doubt it would amount to more than a quart. Which would be 2 pounds of capacity. I could be off either way by a factor of 2.
Last summer I did pour sand onto two of the flat top barges until the sand was rolling off the sides. It sunk them up to the top of the barges but they still stayed afloat. It was fun pushing them around because they were so much heavier. The momentum is cool in the water!
