World Navigator, launching in July 2021, will incorporate two Schottel Pump Jets as part of her propulsion system

Spay, Germany, based propulsion specialist Schottel has won a contract to supply state-of-the-art pump jets for five additional expedition cruise ships (with option to include a sixth) for Portuguese-based company Mystic Cruises.

Pump jets diminish ship vibrations for guests’ comfort and minimize cavitation.

Two pump jets will be installed on each of the 126-meter-long and 19-meter-wide luxury ships, under construction or on order at West Sea Viana Shipyard in Portugal.

“Our goal is to build the cleanest, safest and quietest expedition ships that meet and exceed the strict requirements of the regions where our ships will sail,” said Mário Ferreira, Chairman of Mystic Invest, parent company of Mystic Cruises. “These Schottel exclusive thrusters are perfect for bringing guests closer to more marine wildlife – safely and sustainably. We can stop our ships’ propellers and engage the pump jets to quietly cruise up to five knots in wildlife-rich waters and not frighten away the beautiful fish. Schottel’s Pump Jets are very effective aboard previous Mystic Cruises ships, and we have again opted for Schottel’s system for our Atlas Ocean Voyages expedition ships.”


Each of the new expedition cruise vessels will be equipped with two type SPJ 82 electrically driven Schottel Pump Jets, each rated at 335 kW each. The extremely compact SPJs are not only being installed flush with the hull of these new vessels, but also in a small recess further protecting the propulsion unit. The elastic mounting leads to minimized noise and vibration levels. Pump jets diminish ship vibrations for guests’ comfort and reduce cavitation, which significantly decreases underwater noise.

The pump jets will be equipped with the patented and DNV-GL type-approved Schottel LeaCon sealing system. This system ensures continuous leakage control of the seals and prevents water from entering the gearbox. Of even greater importance, they prevent oil from escaping into the seawater, supporting Mystic’s holistic environmental-friendly cruise approach. Considered a non-oil-to-water interface, the system complies with the VGP


Each of the new expedition ships, being built for Mystic Cruises’ North American brand Atlas Ocean Voyages, can accommodate up to 196 guests in luxury suites and staterooms.

Safety is at the core of Atlas Ocean Voyages’ Polar Category-C and Ice Class-1B certified expedition ships. All vessels’ construction will incorporate modern hygiene and cleanliness measures into their design.

The construction of the first ship World Navigator is on schedule for launch in mid-2021, with four sister-ships set to to launch before the end 2023
