Catamaris Explorer 78 Power®

A luxurious, spacious full custom ocean-going explorer motor catamaran for worldwide blue water cruising and circumnavigation, also for expeditions to the Arctic, through the Northwest Passage and to the Antarctic. 

Hulls, deck, deckhouse and the entire structure are built from certified aluminium. Safe, sturdy, reliable, robust and fast. 

The result is a strong, homogeneous and torsion-resistant structure without the annoying creaking noises that can occur with GRP structures or mixed forms such as hulls made of aluminium/deck and superstructure made of GRP in rough seas. Built in our shipyard in Holland.


Perfect for an owner with large space requirements.

Unlimited layout possibilities: e.g. master suite in the hull or on the flybridge, 2 or 3 guest cabins, crew cabins...

The recessed cockpit lounge on the foredeck is accessible from the outside via the walk-around decks, it can also be designed through a door from the saloon.

Reinforcements approx. 30 cm above and below each of the 4 waterlines from the bow to approx. 40% of the ship's length (on request also over the entire length) as well as bow reinforcements and crash boxes with watertight bulkheads provide increased protection against ice floes, containers and flotsam.

On request, the hulls of Catamaris® Explorer Yachts can be shaped below the waterline to prevent horizontal pressure on the sides when stuck in ice. The hulls then lift out of the water when lateral pressure is applied and cannot be pressed. 

The yacht is built in class 5083 H 321/H111 aluminium, which is certified by "German Lloyd, Bureau Veritas or Lloyd's Register". Strong highly effective cold foam insulation inside provides protection against heat and cold and contributes to a comfortable indoor climate. More about the advantages of aluminium.

The range with 2 x 3.000 litres is 3.200 nm at 8 knots and 2.900 nm at 9 knots.

Available with conventional diesel engines or with the innovative electric hybrid system "Green Eco Power Supply".

Headroom in saloon 2.25 m, in hulls 2.20 m. CE Certification Category A with 12 persons.
