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
