GROOT AMMERS _ The Zeelander fleet of luxury Cor D Rover-designed motor yachts stretches to well over 30 vessels by now. This summer, Zeelander will deliver its fastest to date: the 17m. Z55, equipped with 2 Volvo Penta IPS-1350s.

And next year, Zeelander Yachts will launch a new flagship: the 20m Z66 which promises to be very fast (+40kn.), very high-end.

The yard says it developed the Z55 based on market feedback and calls it “the new benchmark” for luxury in motor yachting. It is 27% longer than the Zeelander Z44, yet packs twice as much volume. Zeelander says its clients say the Z55 is the perfect size for sailing without a captain and for finding a suitable berth.

The Z55 boasts very high-end finishing and materials and offers 360-degree views from 6 seats in the cockpit. The yacht with the Volvo Penta IPS-1350s will have a set of 12.8-liter engines with forward-facing, counter-rotating propellers. It will have a top speed of 42 knots. Despite all that power, the Z55 is remarkably quiet, courtesy of a sound and vibration-absorbing construction.

The Z55 has 4 headlights and 3 bedrooms: a master suite with a vanity table, a VIP suite and a guest cabin with bunk beds that can double as crew quarters. The Z55 has a tender garage and a transom swimming platform.

In developing the Zeelander Z55, the company says it carried out 3 sets of Computational Fluid Dynamics calculations with the experts at Van Oossanen Naval Architects. And Volvo conducted additional tests to ensure its engines are compatible with Zeelander’s design.

The Z66 to be unveiled next

year will be 20m long _ 22m if you pull out the swimming platform _ and a 6m beam. The result: a voluminous yacht with an airy, luxurious interior.

But also an evolved model. Leonardo van den Berg, Zeelander’s commercial director says the Z66 will have “a wider stern and even more curved surfaces. The exterior design was inspired by the way Porsche incrementally evolves its designs over time.” Zeelander yacht is not releasing any photos of the Z66, Just this teaser shot (lower photo).
