McConaghy MC86 Buyer's Guide
The McConaghy MC86 is the 86-foot flagship of McConaghy's historic catamaran range, designed by Ker Yacht Design and built to Bureau Veritas structural standards. On the brokerage market she appears as a semi-custom large cruising catamaran whose principal appeal is customization: owners tailored interior layouts, equipment, and deck configuration to individual wishes, so no two examples present identically. She is offered in an open flybridge version or with a closed upper deck, and the open variant's elevated twin-helm seating area is reached by a staircase from the aft deck.
Layouts on the Used Market
Because the MC86 is fully customizable, the used boat you inspect may differ substantially in cabin count and social layout from another. The accommodation can be divided between the port and starboard hulls to owner specification, and the builder's crewed-charter suggestion placed a master and VIP double to starboard with a guest twin and double to port plus a forward bunk for three — but many private boats will instead consolidate those volumes into fewer, larger staterooms. The main saloon is open plan with a lounge, dining table, and a galley built around a centre-console breakfast bar, and full-height glass sliding doors open onto a spacious aft-deck lounge for outdoor meals. A large sun pad sits forward of the superstructure, while the saloon and hull headroom range from 2.0 to 2.4 meters and 2.0 to 2.3 meters respectively.
Equipment and Common Upgrades
The most consequential equipment clusters for a buyer concern propulsion, water access, and power endurance. Standard power is listed at 2x 150hp, though the reviewed example carried 2x 250 HP engines, so verify the actual installation and its service history. Fuel capacity is 3,000 liters and fresh water 2,400 liters, supporting the published claim of great range under power. A hydraulic beach club platform aft simplifies tender handling and creates a water's-edge terrace with room for a sun lounger, and the flybridge's extended aft overhang provides stowage for water toys. Dynamic glass panels with UV-reflective glazing run the length of the hull sides and top a predominantly glass superstructure, so inspect the seals and framing as part of any survey.
What to Inspect
The MC86's structure is built to Bureau Veritas standards, but a survey should focus on the elements most exposed by her configuration. The extensive glazing and near-full-beam glass superstructure warrant close examination of the seals and bonding where hull and superstructure meet. The central carbon daggerboards plunge to about six meters and are central to her close-winded performance, so their trunk integrity and raise-lower mechanism should be checked. The hydraulic beach club platform is a moving, load-bearing aft structure — its rams, hinges, and seals are a point of failure worth dedicated inspection.
Availability and Buyer's Takeaway
Regional availability is not itemized here, so inquire through appropriate brokers rather than assuming local stock. For a buyer, the essentials are: confirm whether the boat is open-flybridge or closed-upper-deck; verify the actual engine model and hours against the 150hp or 250 HP possibilities; inspect daggerboard trunks and hydraulic platform; and assess the bespoke interior against your own accommodation needs since layouts vary widely.
- Confirm flybridge type and helm-access staircase condition
- Survey glazing seals across the full-beam superstructure
- Check carbon daggerboard trunks and deployment gear
- Verify engine specification and fuel/water tank integrity
- Match the customizable hull accommodation to intended use
