Finding Nemo Submarine Voyage - The Submarines

The Submarines

The attraction reused the eight original Submarine Voyage thru Liquid Space attraction vehicle hulls built at the Todd Shipyards in San Pedro, California. Vertical rollers attached at each end of the keel roll within a submerged guide channel. The original diesel engines were replaced by electric battery-powered propulsion units which are charged at the loading dock by contactless inductive coils, increasing efficiency and eliminating fuel spills. Guests board through a hatch at either end by crossing hinged loading ramps and descending spiral stairs. Twenty aft-boarding guests are seated facing the starboard side and fore-boarding guests are seated facing port. Each submarine originally seated 38 guests, but removal of the diesel engines increased seating to 40 spring-loaded fiberglass seats. Lap sitting of small children is permitted. 46 on-board flotation devices limit maximum capacity to 45 guests and one helmsman. When the boarding ramps are raised the hatches are sealed watertight (but not airtight) and mooring lines released. Although their viewports are below water level, the "submarines" do not actually submerge when "diving". Descent and submersion is simulated with bubbles that rise across the viewports when the vehicles pass through compressed air released under the hull and waterfalls. Each viewport blows fresh dehumidified air across its glass to prevent fogging. Each cabin interior has 40 viewports framed with dark blue mesh, and a wavy blue stripe painted across the ceiling. The original subs's exteriors were painted navy gray; the new livery colors are bright yellow above water, a light blue 'boot stripe' at the waterline, and a reflection-reducing matte blue-black below the waterline.

The sail of each submarine (from which the helmsman operates) has a control console and a board of indicator lights displaying the submarine's operation status if anything abnormal were to happen on the ride's cycle. Cast members on this ride are trained on how to respond to each abnormality, and are always in contact with other operating positions of the ride. Although the submarine is on a guideway, the helmsman controls its forward and backward movement via a small joystick to regulate these speeds (shown in RPMs, in lieu of the actual propeller which moves the boat) which vary in different sections of the ride. Cast members operating the submarines must guide the submarine through a series of laser sensors, each which activate a different scene for the show. Guiding timers and block-lights are placed throughout the ride to help the cast member properly time each scene. Helmsmen cast members are also able to unlock the watertight hatches via levers in the sail, which is done each time the boat arrives to dock. Each sail also carries a flashlight, opening/closing checklists for the ride's opening/closing crew, and a radio to communicate with other boats and stations in the attraction.

The queue, docks, subs and scenes have all been re-themed to represent the movie's Australian harbor, and the narrator and his first mate speak with Australian accents.

Marine Observation Outpost (M.O.O.) - Guests see a show on a high definition LCD screen which is similar to the underwater attraction. This alternative experience is provided to accommodate guests with conditions preventing them from boarding the subs. This "virtual" version was filmed from aboard the submaries before the attraction opened to the public, and includes a few minor features that were subsequently removed from the actual attraction.
