MS Mariner of the Seas is one of five Voyager-class cruise ships from Royal Caribbean International.
Mariner of the Seas is in the second generation of Voyager-class vessels. It has a capacity for 4,252 passengers. The Mariner differs from similar vessels in that the rear buffet (Windjammer) extends farther aft, and also includes "Jade", an Asian fusion buffet. She has glass balconies which her first generation sisters lacked. She was identical to the Navigator of the Seas, which shared the same design upgrades, but Navigator of the Seas was enlarged during a 2014 revitalization by 1,291 GT.

Technical
Main propulsion
The ship has a diesel-electric powertrain using three Azipod azimuth thrusters. Each propeller is driven by a double wound 3-phase synchronous motor with 4-bladed fixed-pitch bronze propellers. The motors are mounted outside the hull directly on the propeller shaft inside the pod. The three propellers are arranged so that the center propeller is a pushing on-azimuthing Fixipod-type and the two wing ones are of pulling-azimuthing-type steering propellers.
- Motors: three 14,000 kW (18,800 hp) at 145 rpm each
- Total: 42,000 kW (56,000 hp)
- Stabilizers: 4 Brown Brothers Stabilizer Fins
- Bow Thrusters: 4 KAMEWA 3000 kW each
- Maximum speed: 24 knots (44 km/h)
- Fuel consumption at full speed: 10,637 kg/h (2,871 gal/h)
Although the ship is equipped with anchors, because of the azipods, bow thrusters and GPS navigation the Mariner in good weather is capable of maintaining station without anchoring. Thus, in ports without berthing facilities such as Cabo San Lucas, Mexico, the ship does not generally drop anchor, and maintains position automatically. This helps to reduce damage to coral that may lie at the bottom in bay waters.
Generators
Six Wärtsilä Diesel 12V46 generators producing 12,600 kilowatts each for a total of 75,000 kilowatts or 103,000 bhp. All gensets are monitored by the Wärtsilä CBM (Condition Based Maintenance) group by using Wärtsilä automatic data sending concept.
Fresh water production
The ship has three ways in which to produce fresh water--Two Alfa Laval Desalt Flash and Energy Recovery Evaporators and one Pall Rochem seawater desalination unit (reverse osmosis) "Rosmarin" 80404-50/300-A-SW
- Steam evaporator: 230,000 gallons (900 metric tons) per day
- Seawater desalination unit (reverse osmosis): 80,000 gal (300 t) per day
- Total freshwater production: 540,000 gal (2,100 t) per day
- Water consumption: 58 U.S. gallons (220 liters) per person per day
- Ice cube production: 65,000 lb (29,000 kg) per day

Staterooms
As a second-generation Voyager-class ship, the Mariner of the Seas' balconies are affixed outside the ship's superstructure, providing better views. All staterooms have a 2-bed configuration that can be converted into a queen-sized bed. Other amenities include private bathrooms, phone, TV, and air conditioning. Many of the ship's interiors were decorated by muralist Clarissa Parish.
- Total staterooms: 1,557
- Ocean view: 939 (includes 765 with balconies)
- Interior: 618 (includes 138 with promenade view)
- Staterooms with 3rd & 4th berths: 569.
- Wheelchair-accessible: 26
