McConaghy Ker 40+ Buyer's Guide
The McConaghy Ker 40+ is a 41-foot one-design racing monohull built in 2015 under the Fast40+ rule, constructed by McConaghy in carbon/epoxy/foam with an ISO OSR rating of 1. For a buyer scanning the used market, the appeal is a proven grand-prix platform: the design took the 2017 UK FAST40+ IRC National Championship and kept winning through 2020. Because she is a one-design, the structural and rig specification should be identical hull to hull, leaving condition and race prep as the variables that matter.
Layouts on the Used Market
The boat is a racing monohull of one-design build, so any used example should be judged as a race boat first. A buyer should expect the class-spec interior rather than negotiating layouts, and viewing a specific hull is the only way to learn the berthing and systems fit given the racing focus.
Equipment and Common Upgrades
The as-built race systems came from Southern Spars for the spars, Lewmar for deck hardware, and B&G for electronics anchor, which together define the boat's grand-prix standard. For a buyer, that means the critical race systems are name-brand and class-controlled; any deviations from that fit should be questioned as non-class or later modification. The rig's 98-square-meter upwind and 248-square-meter downwind areas are fixed by design, so sail inventory condition, not plan, is the negotiation point.
What to Inspect
Standard used-race-boat survey practice applies; the boat presents as a clean one-design with no flagged structural or systems faults in the available material.
Availability and Buyer's Takeaway
For a buyer, the takeaway is straightforward:
- Confirm one-design class compliance with Southern Spars, Lewmar, and B&G equipment
- Verify ISO OSR 1 and ISO Structural A documentation
- Inspect sail inventory against the 98 and 248 square-meter rig areas
- Review race records for the specific hull from 2015 through 2020
