Design and Construction
The hull is vacuum-bagged vinylester resin with biaxial and unidirectional E glass incorporating varying thickness Divinicell in the outer skin, a sandwich approach that keeps weight down while preserving stiffness. Test sailors confirmed the brand-wide galvanized steel grid support glassed into all X-Yachts, which makes them strong and stiff. The bow is nearly plumb with a fine entry and a knuckle sitting just out of the water, while the cabin top is low and unobtrusive, partly a function of the high freeboard. With a beam of 12.47 feet and a displacement near 15,000 pounds, the boat carries 5,291 pounds of lead ballast in a bulb keel drawing 8.04 feet, and owners report a relatively narrow waterline beam with lower wetted surface than boats of similar size, a shape that favors clean tracking and easy acceleration.
Rig and Handling
The mast and boom are carbon-fiber built by Nordic Mast, and the topmast is unusually stiff for a fractionally rigged boat according to owner reports. The backstay is adjusted with a line-driven system using a Fredericksen shaft and drum below deck; X-Yachts claims that the system is quicker and smoother than a hydraulic system and will allow the mainsheet trimmer to put as much as 2800 kgs. of load on the backstay. An underdeck split-mainsheet system leads just forward of the wheel, and the boat comes with a hydraulic mast jack plus a choice of Frederiksen or Harken hardware, with running rigging in Vectran and Spectra. On the water, test crews sped upwind at 7.5 knots and exceeded 10 knots with little effort running with a symmetric chute, a 1,308-square-foot kite in the tester's configuration. The PHRF rating is 42, and the sail plan centers on a 514.7-square-foot main with genoa options from 437 to 585.6 square feet plus a 1,412-square-foot spinnaker.
Accommodations
Below, the IMX 40 is a varnished mahogany cabin with recessed lighting, a cruising concession inside an otherwise race-oriented shell. Aft are equal-sized molded-in quarter berths, each with an adjacent hanging locker and a pair of removable pipe berths, giving flexible sleeping for a racing crew or a couple with guests. Stowed beneath the port settee is the 25-gallon fuel cell, opposite the 50-gallon fresh water tank below the starboard sofa, a symmetrical layout that keeps tankage low and central.
Equipment and Power
Deck hardware is either Fredericksen or Harken depending on the buyer's preference, and the engine is a 40-horsepower Volvo MD 2040-s saildrive with a two-blade Flex-O-Fold racing propeller, matched to a three-cylinder Volvo diesel noted by testers. The stern is open to a 66-inch carbon-fiber wheel, and a transom locker can be installed for cruising storage and seating, or left off as a racing dock. The boat meets European CE-Certification under directive 94/25/CE, a formal mark of recreational-craft compliance.
The Verdict
The IMX 40 is a purposeful fusion of X-Yachts' racing DNA and just enough cabin to cruise, built in meaningful numbers and proven at the front of European fleets. Its sandwich hull, steel grid, and carbon rig deliver stiffness and pace, while the low cabin top and narrow waterline keep it light on the water. The trade-off is a deep bulb keel and a racing interior that rewards sailors who want speed over creature comfort.
Pros
- Immediate regatta success, including an IRM Championship win on hull #1
- Vacuum-bagged vinylester sandwich hull with brand-standard steel grid for stiffness
- Carbon-fiber mast and boom with an unusually stiff fractional topmast
- Line-driven backstay claimed to exceed hydraulic speed and reach 2,800 kg load
- Strong upwind and downwind pace, 7.5 knots upwind and over 10 with a chute
Cons
- 8.04-foot draft limits shallow access
- Racing-oriented interior with minimal cruising furniture beyond berths and tankage
- Saildrive with two-blade folder prioritizes speed over motoring torque
