CNB 100 Buyer's Guide
Shopping the brokerage market for a CNB 100 means entering the rare air of 30.5-meter custom superyachts, a 2009 delivery from Construction Navale Bordeaux with exterior by Luca Brenta and interiors by Wetzels Brown Partners. These are not common boats, but understanding the layouts and upgrades seen on the used market helps a serious buyer focus a search in the right regions and ask the right questions at survey.
Layouts on the Used Market
Owner three-cabin arrangements are the more common configuration encountered among used CNB 100s, though other layouts do appear. Ex-charter examples are common, which means a buyer should verify whether a candidate spent time in fleet service and assess wear accordingly. The coachroof of 78 glass panels and the Wetzels Brown Partners interior with Gaggenau galley and Miele appliances carry through regardless of layout, giving every example a bright, residential feel below decks.
Equipment and Common Upgrades
On the used market, teak decks, watermaker, air conditioning, inverter, freezer, hot water, hardtop, radar, autopilot, chartplotter, and life raft are commonly fitted, establishing a strong baseline for bluewater autonomy. Often-seen additions include heating, asymmetric spinnaker, bow thruster, electric winches, washing machine, bimini, swim platform, dinghy davits, AIS, and a short-handed setup that simplifies sailing with a small crew. The CNB 100's own build specification already included hydraulic winches, a hydraulic operated transom, twin 2016 generators, B&G electronics, and a carbon fibre cockpit hard-top, so buyers should confirm which often-seen comforts have been added versus which were original.
What to Inspect
A survey should examine the teak deck for wear, the hydraulic systems for leaks or pressure loss, and the 78-panel coachroof for seal integrity given the extensive glazing carbon fibre deck and hull construction. The twin generators from 2016 warrant run-testing under load, and the Cummins engines rated at 355hp should be checked for service history consistent with the boat's size and usage profile.
Availability and Buyer's Takeaway
Typical markets for the CNB 100 are Italy, Greece, and the United Kingdom. For a buyer, the takeaway is to prioritize a surveyed hull and hydraulic systems, confirm layout and ex-charter history, and expect a well-equipped baseline with commonly fitted autonomy gear already in place.
- Verify teak deck and 78-panel coachroof sealing
- Test hydraulic winches, transom, and magic trim
- Run twin 2016 generators and Cummins engines under load
