Best for
- Extended family coastal and Great Lakes cruising
- Owners wanting modern passagemaker comfort with speed reserve
- Buyers with marina access for a 48-foot yacht
Trade-offs
- 19-foot bridge clearance is a major inland-route constraint
- Twin diesel and yacht-scale systems raise maintenance cost
- 14-foot-9-inch beam requires substantial marina infrastructure
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
- Inspect twin Cummins engines, shafts, cooling and exhaust
- Inspect flybridge structure, T-top options and exposed systems
- Inspect side door, glazing and roof penetrations
- Review generator, battery, charging, sanitation and domestic systems
