NORDHAVN 52
Nordhavn 52
Overview
The new N52 differs itself from the 47 with three central design modifications – each of which combines to make a sleeker and slightly more efficient boat. The most significant of these changes is a cockpit extension, which opens up the rear of the boat as well as elongates the yacht's lines. But the benefits of added waterline length aren't limited simply to aesthetics. The design team was able to work an extra (approximate) 200 gallons of fuel into the capacity of the boat's tanks and in turn, bump up the range.
To coincide with the elongated cockpit, the upper level boat deck was lengthened by two feet – a move that serves a dual purpose: not only does this offset the cockpit extension, it enables a bigger tender to be carried on top. Completing the enhanced look is the re-configuration of the flybridge. A purely cosmetic change (no features have been added or altered), the newly-styled flybridge is now more integral with the boat deck and pilothouse roof.
Despite these differences, the N52 is exactly like the 47, and the rest of the Nordhavn line, in her robust construction, superior level of fit and finish, and an ability to deliver her owners anywhere they wish to travel in safety, comfort and luxury.
