・・・ British naval architecture studio Laurent Giles has opened up about a new explorer concept of 51 meters in length, Challenger 55, which can serve both as a commercial vessel and a research charter yacht thanks to its advanced technical capabilities and onboard amenities. . The Lloyd’s classed boat will have a hybrid propulsion system, allowing for a range of 6.000 nautical miles at an economic speed of 10 knots, which means that cruising to most remote locations for up to 25 days without refueling on shore will be feasible with Challenger 55. In turn, the use of electrical power ensures the less environmental footprint possible. Smart dynamic positioning permits to access eco-sensitive areas, without disturbing seabeds or dropping anchors on corals. The leisure yacht sector borrows this technology from support vessels that have to maintain their position next to oil platforms. . The fundamental features for an expedition yacht include an aft-deck helipad, A-frames for launching and recovering submarines and a large tender storage. . The interior layout comprises a full-beam master suite complete with a private lounge, five double guest cabins on the main deck and crew quarters sharing the lower deck with the technical spaces and an on-board laboratory. . Earlier this year Laurent Giles introduced a 110-meter superyacht concept Hemy.
