Abstract: A toy ship and associated toy navy wherein the toy ship has multiple chambers within the hull, each chamber having a plug below the water line to allow entry of water to sink the ship. The child determines as a matter of play that the ship has been struck by a projectile or torpedo and appropriately should have one or more plugs pulled. The child then pulls the plug(s) allowing entry of water to sink the ship. As the ship is struck further, more plugs may be pulled by the child to hasten sinking of the ship. The plugs may be fabricated to remain with the ship when pulled so as not to get lost or become a swallowing hazard for the child. The ship may be provided in association with a toy submarine, a toy airplane and/or a second toy ship, which may be of different design.

Abstract: Pontoons along both sides of the vehicle can be filled with either air or water, at the user's preference. When the pontoons are filled with air the vehicle floats in water and is driven along the water surface by a propeller and also by a tread drive. When the pontoons are filled with water the vehicle sinks in water and is driven along the bottom by, again, the propeller and treads. In either event when the vehicle comes to a dry surface it continues to be driven along that surface by the treads. The pontoons are provided with a hole and plug for use in filling or draining them. Preferably the interior spaces of the pontoons communicate through a cross-connection chamber that rougly equalizes the amount of water in the two pontoons, so that the vehicle has minimal tendency to capsize or ride in the water at a cant. An unusual two-worm-and-worm-gear drive train provides power to the tread drivers both fore and aft with high mechanical advantage and very few moving parts.
