One week ago today, the largest-volume 180-foot (55-meter) megayacht under construction in The Netherlands took a significant step forward. Project Castor, a.k.a. Heesen hull number 19055, had her hull and superstructure come together.
Available for sale for a springtime 2020 delivery, Project Castor is the fourth megayacht so far in Heesen’s 55M Steel series. Therefore, she has a steel hull—specifically, a fast-displacement hull from Van Oossanen Naval Architects. This means the megayacht should see better fuel efficiency and low resistance throughout the entire speed range. As for speed, anticipate a 13-knot cruise, which in turn should allow for a 4,500-nautical-mile range. Top end, meanwhile, should be 15½ knots, under twin MTU power. On a related note, her power package will meet the IMO Tier III regulations regarding emissions. (In fact, the regulations aim for an 80-percent reduction in nitrogen oxide.)
Displacing 760 gross tons, Project Castor has the distinction, as mentioned above, of being the largest Dutch megayacht by volume in build right now. Omega Architects’ styling still keeps her looking sleek and sporty, of course, and recognizable as a Heesen. She does, however, have some differences in comparison to the three previous deliveries in the series. For example, rather than sit below decks, the VIP stateroom is up on the bridge deck. This, in turn, provides more floor space for the remaining guest staterooms down there. The master, meanwhile, is larger as well, 786 square feet (73 square meters).
Interestingly, even with the upper VIP, Project Castor still has a skylounge. It’s full beam, too, occupying 1098 square feet (102 square meters). The megayacht’s beam: 31 feet (9.6 meters).
Interested buyers can still personalize the megayacht. In the meantime, Bannenbeg & Rowell is imagining warm tones for the woods, stones, and other materials. Overall, the look is contemporary.
