FlowRiders (surfing simulators)

Harmony OTS has two FlowRiders (RCI's signature surf simulators) located aft (portside and starboard).

Pumps project high-speed water (20-30 mph / 30-50 kph) across a small area creating sheet waves (stationary waves) to simulate ocean surfing. FlowRiders were first created as land-based facilities and were implemented by Royal Caribbean for guests to enjoy traditional surfing and skimboarding on cruise ships.

Royal Caribbean's FlowRiders are complimentary (cruise fare inclusive) and reservations are not required. Equipment (bodyboards and flowboards) is provided.

Private surfing lessons are available for booking at an additional cost per person. Groups are 6 to 8 guests.

The FlowRider's minimum height restrictions are 52 inches/132 cm (to use the bodyboard) and 58 inches/147 cm (to use the flowboard). Not allowed are footwear, goggles, go-pro cams.

Guests can surf at the simulator until they fall off the board.

The facility is supervised by sports staff (safety, assistance, advice).

Ultimate Abyss Dry Slide

Aft on Deck 16 (entrance point) is the 10-story high dry slide "Ultimate Abyss" (introduced on Harmony OTS) - the tallest slide at sea, having height 150 ft (46 m), length 216 ft (66 m) and providing ride speed 9 mph / 14 kph.

Lido Deck is the entry-level. The launch area is located all the way aft (accessible via stairs near Wipeout Cafe) and features a see-through glass platform. Guests take a mat and slide all the way down to the Boardwalk - twisting and turning in a serpentine-like movement. The dry slide ends at the AquaTheatre's pool on deck 6 (aft).

Ultimate Abyss is a spiraling slide with 2 separate cylinders (symmetric to each other, each tube is 2,6 ft / 0,8 m in diameter) made of stainless steel and colored in purple. This is a vertical drop slide located in the Sports Zone's pool (aft-ship location).

The facility is complimentary and advance reservations are not required. The experience starts with a walk across a plank into the jaws of an anglerfish and boarding one of the specially designed mats. Slide mats are colored in black, each with an opening for the feet and a strap to hold on to. Follows the vertical drop (27-degree) some 92 ft / 28 m down to the Boardwalk.

The average sliding time (from the top to the bottom) is 12-13 sec. To avoid injuries (arm and leg burns during the ride) keep the legs straight and elbows in.

The Ultimate Abyss slide is dark inside (the tubes are intransparent) there are special sound effects and lighting produced by around 300 LED lights, as well as various graffiti artworks on the walls.

The dry slide's restrictions are a minimum height 44 inches (112 cm) and max weight 300 pounds (136 kg).

Harmony OTS has 3 other slides/waterslides grouped in "The Perfect Storm" complex (entry-level deck 18 forward). These are the spiraling race-slides "Cyclone" and "Typhoon" (colored, respectively, in yellow and blue), and the "Supercell" (colored in yellow and green).
