Best for
- Couples or families wanting substantial traditional accommodations
- Extended inland and coastal cruising
- Buyers prepared for larger-boat maintenance
Trade-offs
- Large exterior teak burden and aging systems can require major refit
- Beam, height and displacement increase marina and haul-out costs
- Construction details vary among imported hulls
- Comfortable coastal size should not be confused with verified offshore capability
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
- Moisture-test teak-deck fasteners, deck penetrations, window surrounds and cabin-house joints
- Inspect fuel tanks, fill and vent hoses, supports and access for corrosion or leakage
- Inspect original wiring, shore-power equipment, bonding and later electrical modifications
- Inspect exhaust systems, engine mounts, shafting, rudders and steering gear
- Confirm builder, model configuration and major refit history from hull documentation

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.
