THE KROGEN WHALEBACK 48'
Long Range | Liveaboard | Trawler Yacht

With her rugged full displacement hull and defiant, unfettered profile, the Whaleback 48' readily reflects the proud heritage of the trawler-inspired Kadey-Krogen fleet. This bold, new Krogen yacht launches an advanced level of life at sea: One single, stepless level of full-beam openness and spaciousness, stem to stern. The result: An intrepid 48' transocean trawler with the luxuriant livability few 60 footers enjoy, still of a size and agility that is easily handled by a couple.

The full body saloon is a delight of natural light. The convivial galley is equipped to the nth inspiring even reluctant chefs to new culinary heights. The midship houses two generous staterooms for guests. Forward, nicely private, and greatly privileged in size is the master stateroom with queen-size sleeping, large master head with shower and loads of storage. An interior staircase makes it a quick dry commute from the saloon to the all pro pilot house which goes full circle for all seeing seagoing and deft maneuvering when docking.

Surrounding the pilot house is a massive boat deck with abundant space for personal water craft and cross-country bikes plus loads left free to comfortably handle dock lines. For optimum, limitless cruising, the Whaleback 48' takes you confidently and comfortably to your destination with fuel economy every knot of the way.
