Kadey-Krogen 42
1977–1998
The Kadey-Krogen 42 is a purpose-built cruising design from a builder focused on displacement-speed efficiency and long-range use. The family emphasizes substantial tankage, protected single-screw propulsion and liveaboard-oriented interiors; the 38 Cutter is the major exception, combining shoal-draft sailing capability with auxiliary diesel power.

Best for
- Couples planning extended liveaboard and long-distance cruising
- Owners prioritizing range, efficiency and protected machinery
- Buyers comfortable with displacement-speed passage planning
Trade-offs
- Low-speed cruising requires patience and weather planning
- Large tankage and systems increase refit and maintenance scope
- Beam and displacement of larger models materially affect marina and haul-out options
Known concerns
- No model-specific concern has been promoted to B-Atlas’s evidence threshold. This does not mean the model has no age-, condition- or hull-specific risks.
Inspection focus
- Verify model generation, build year and engine installation from factory documentation
- Inspect cored decks, windows, hatches and hardware penetrations for moisture
- Inspect tanks, fuel transfer/filtration, exhaust and cooling systems
- Inspect shaft, rudder, stern gear and keel protection
- Review electrical, charging, generator and navigation-system refits

About this record
B-Atlas preserves uncertainty: missing information remains unknown rather than being treated as a negative. Specifications and guidance describe the model record; individual boats can differ by year, equipment, refit and condition.
