Another scratch-built boat The Elizabeth, the barge scale is 1/16 = 52" x 6½" motor is a Decaperm 6v geared. Built from photos and no plans, the barge has two interchangeable cargo holds. One is a typical tarpaulin-covered and the other showing off its load of hand-ball coal plus some timber upfront. Slightly cheating I installed a homemade bow-thruster using a car screen washer motor which pumps water out either side. In fact so effective it will turn in its own length. For stability, the barge is flat bottomed.
