NORDHAVN 47

Nordhavn 47

Overview

This Model Is No Longer In Production

Nordhavns have been setting records since the very first N46 was launched in 1989. Indeed, more Nordhavns have made successful ocean passages and global circumnavigations than all other production powerboats combined. In 2002, a Nordhavn 40 completed a 26,000-mile circumnavigation in less than 26 weeks without a single breakdown or mishap.
