2003–2007
The Sea Ray 390 / 40 Motor Yacht is a production aft-cabin motor yacht built around high interior volume, two-stateroom privacy and twin-engine coastal performance. Its multi-level deck plan trades easy all-on-one-level movement for substantial accommodation in a relatively modest overall length.

Best for
- Couples or families prioritizing accommodation over low operating cost
- Inland and coastal cruising with marina-based use
- Buyers wanting two private sleeping areas
Trade-offs
- Multiple steps between swim platform, aft deck, bridge and cabins
- High windage and relatively high air draft
- Twin-engine operating and maintenance cost
- Age and system complexity make condition more important than model reputation
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 moisture around deck hardware, windows, hatches and rail bases
- Inspect fuel, water and waste tanks plus hoses and fittings
- Inspect engines, transmissions or sterndrives, exhaust and cooling systems
- Review AC/DC wiring, shore-power equipment and documented electrical modifications
- Confirm steering, trim-tab and generator operation where fitted
- Inspect aft-cabin windows, aft-deck enclosure and access steps
