About
2017 McConaghy MC31 designed for competitive racing and fast, rewarding sailing, offered with a comprehensive sail wardrobe, quality electronics and a road trailer.
FURTHER BROKER’S COMMENTS:
This racing McConaghy model is Hull No.7 of the McConaghy MC31, built in 2017 by McConaghy Boats and designed by Dunning & Associates Yacht Design. She is a focused 31-foot performance racer with a clean hull form, deep keel, and high ballast ratio, built without rating-rule constraints and suited to both local racing and offshore racing.
Her current specification reflects previous HP30 Class use in Southern England. For IRC optimisation, the inboard engine and diesel tank were removed, the keel was shortened by 20cm to a 2.40m draft, and overall displacement was reduced by approx. 250-300kg from original.
She has been measured under IRC, ORC and Swedish SRS, and is offered with an extensive North Sails wardrobe, B&G H5000 race electronics, lithium batteries, 2024 Coppercoat bottom treatment and a Böckmann road trailer.
With a liftable keel for trailer handling and a two-section Southern Spars carbon fibre rig with mast jack, she is set up for practical transport as well as competitive inshore and offshore racing.
Her specification highlights include:-
2.40m draft following IRC/HP30 optimisation, with liftable keel for easy trailer and transport handling
Approx. 1,900kg displacement and 640kg keel weight
Southern Spars carbon fibre rig and rigging, with carbon fibre elliptical stanchions
Two spreader, two-section mast with mast jack for rig tuning
Engine and diesel tank removed for IRC/HP30 optimisation
Full North Sails wardrobe
B&G H5000 race electronics with AIS and B&G Vulcan 7 plotter
Harken gear package
Lithium batteries
Holmatro hydraulic pump / mast jack
2024 Coppercoat bottom treatment
Tohatsu 4.5hp outboard engine
Böckmann TPV BA3500R trailer and land storage cradle included
MANUFACTURER’S COMMENTS:
“The MC31 is a performance club racer and was born from a desire to create a boat and class that gave owners and crew the most rewarding time on the water.
The MC31 features an unprecedented performance-driven hull form and carefully considered systems and deck layout, which enhance the sailing experience and make it ideal for One Design and Club Racing with Offshore Capabilities.
McConaghy Boats has invested considerable time and effort to ensure the boat and the class rules delivered on the objectives that other classes had failed to do.”
PRESS REVIEW:
“The MC31 one-design, built by McConaghy Boats in Australia, looks to be a very fast boat. The design is most interesting but I really had to dig through the company’s material to find the designer’s name, Harry Dunning.
The McConaghy team appears to have pulled out all the stops to endow this design with every possible speed-producing feature. The promotional material makes a point of stressing the efforts they went to so that they could reduce weight. They quote the famous race car engineer, Colin Chapman, saying “To increase performance, add lightness.”
The first thing that grabs me when I look at this hull is that in plan view (looking down at the deck) there is absolutely no taper to the deck aft. The boat reaches max beam very far forward, just aft of the mast, then stays there to the transom with wide, flaring sections. My guess would be that the disposition of beam is for crew hiking effectiveness. I can’t find a DWL listed in the specs, so I’ll guess the DWL is 28 feet 6 inches for a D/L of 90.36. That’s light but not as light as the promo material suggests.
There is no chine but the bilge turn aft is quite hard. Amidships the bottom is very flat with zero deadrise and a moderate turn to the bilge. L/B is 3.00. DWL and LOA are close but there is a little bit of overhang aft, maybe 16 inches.
Draft is 8 feet 6 inches with a long T-bulb on a very high-aspect-ratio, carbon fiber, retracting fin. I have searched the specs but I see no mention of a kelp cutter option. Having just had a kelp encounter in a race two weeks ago, I am suddenly very pro- kelp cutter. This style of T-bulb would be a problem in Puget Sound. The rudder is carbon fiber and very dagger-like in profile.
I get the feeling that a lot of refinement has gone into the deck layout. The deck gear specification is extensive with only two minor options. The material I have is a bit obscure on deck details but what I think I am seeing is an exit on centerline in the cockpit sole for control lines. The mainsheet traveler is aft of the tiller head. The deck forward is perfectly clean except for a very low, sliding hatch for chute work. Note the low drag, foil-shape stanchions. The bowsprit is removable for docking.
This is a very high-powered boat. With 690 square feet of upwind sail area, the SA/D is 39.42. That is a lot of horsepower per pound of boat. Downwind there is 1,710 square feet of sail area. That’s a bit hard to comprehend on a 31-footer. “Time to put your knitting away Mom and get that chute up. Don’t forget your helmet. ” The rig is all carbon fiber.
Construction of the MC31 is e-glass over a foam core and vinylester infused resin. There is a Yanmar 15-horse power diesel with saildrive to get you to the dock. There is kind of an interior. You get a gimbaled stove, some pipe berths, a portable toilet and a cooler that stows under the companionway steps. As I mentioned, for close one-design racing the specifications are very extensive and there is not much you will need to add for some competitive racing.”
