I built this barge to go with my 1/35 scale towboat. It is made of 1/2 inch plywood hull and a 1/4 inch plywood deck. There is a grid of Neodymium magnets spaced on and imbedded flus with the deck.

This barge can be used by itself with different scale boats or used as a 1/35 scale barge with the accessories added. First accessory was the workshop (detailed inside), a pickup truck, toilet, and trash can. Latest (2022) addition is the gantry crane as shown in the photos.
