After the ship is moved to the sinking location, it is positioned on a steel deck structure called a tilt deck. This deck is equipped with flotation devices such that the combined weight of both the deck and the ship is overcome by the flotation force. In other words, the ship is naturally buoyant and requires a downforce to sink it. This force is provided by a rather smallish 8 inch diameter hydraulic cylinder. Push to sink, let off the pressure and the ship and deck rise naturally back to the surface. If the system failed, the ship is always back to roadway level and can be towed home externally.

To safety the tilt deck in the up position against any unusual flotation failure during the ship movement, large upstops are provided which lock the tilt deck in the up position. When the ship is in the sink position, it is locked to the tilt deck. Likewise, the dog is also locked into position in case the cable tried to move.

The behind-the-scenes details of the Britannia are only a small part of the hidden features of the Pirate Battle Show. One could write a large book on all the special engineering and safety precautions that went into this spectacular stunt show. Like, special show feedback devices to prove that the human cast members are in safe positions when nearby fire and explosions occur. A human Technical director oversees all the action from a TD booth located high up on one of the Village buildings. The TD can override any unsafe condition in the show sequence, which is 100% pre-recorded complete with all dialogue, sound, lighting, fire cues, etc. After each show, the pyro EFX must be dried out after sinking, inspected and reloaded for the next show. Enough fire EFX gas must be available for each show, but severely limited as to how much the building code will allow to be stored on site.

After working on my part in the development of this fabulous Las Vegas Extravaganza, I am still amazed at all the trick special designs that everyone developed for their individual areas of expertise. The public could enjoy the spectacle and never know the hidden secrets. But maybe the secrets might be an even more spectacular experience. At least I raised the curtain a bit for you.
