Bought many years ago from Martin Models at E Port spring show. Swapped with a friend who built the model. Now back in my possession following his death. Uses three internal tanks for water ballast plus about 1lb lead to bring to waterline. Has a Tomahawk smoke unit and smells like the real thing. Very stable on the water and looks the part.
