Boats

Based on my research, the classic Boats theme represents a pioneering line of actual floating sets first introduced in 1982, featuring weighted hulls that allowed these models to float in water. The standout Freighter with its on-board crane system demonstrates exceptional versatility, commanding high secondary market prices with mint examples exceeding $300. The rare Tug Boat remains the only minifig-scale tug boat ever released, making it highly sought after by ship collectors.
