After questions from my grandsons as to why most of my ships are water-line models or just sit on shelves, it became apparent that some kind of pond sailer was in order. So, after dragging out an old Lindberg tug kit and dutifully installing batteries and motor, it was ready to take on wading pools or small ponds. I like the lines of the old-time coal-burning steam tug. It is a stable sailer and the little guys are very happy with it
