Trade-offs
- Small flybridge separates helm from crew
- V-drive machinery complicates service access
- Interior and cockpit space compete in a compact hull
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 deck, window and hardware penetrations for moisture
- Inspect fuel tanks, exhaust, cooling, wiring and steering
- Verify engines, transmissions, shafts, drives, struts and rudders as applicable
- Confirm factory propulsion and layout against model year
