I have always had an intention to create some simple functional barges for my armies ever since seeing one in Charles Grants "The Wargame" . So at long last ,after 30 odd years, I've got round to creating some. They are built to a specific size to take exactly two bases of troops (12 figures) with space at front/back for crew and possibly guns.
Construction was relatively simple. I used foamcore rather than balsa as I have a plentiful supply, the bow and stern posts are just scraps of balsa and the sides are thin card, the sort from the back of pads. I picked some that was as thick as possible while still being flexible. Hopefully the pictures give a sufficient idea of the construction.
Why build them now? Well my Frundsberg solo game is just at a stage where a river crossing using barges is about to be fought.
