MC 31 One-Design

The new 31-foot sportboat from Australia's McConaghy Boats adds another powerful option to the growing 30-foot class.

An update from McConaghy Yachts, of Australia, says its first MC 31 One Design will be sailing in Sydney in November with boats two, three, and four remaining in Australia and boats five and six bound for a new operation in Newport, R.I. (McConaghy USA).

The design and specification of the MC 31 has matured over the past few months, they say, with the hull shape and balance of the sail plan and foils being refined by Naval Architect Harry Dunning right up until the time the CNC robots started cutting the molds.

Recent developments to the rig and deck layout include the upgrades listed below, including many options that add to overall price, which is listed as $125,000 for the base one-design boat. Owner/driver class rules will apply.


• Mast and deck layout now set up for Fractional Code Zero as standard • Fractional spinnaker halyard now standard on all boats in addition to one masthead spinnaker halyard • Optional bullet lock for fractional spinnaker halyard to ensure tight luff on FRO • Optional port-side tack line in addition to starboard-side tack line as standard • Optional port masthead halyard • Optional halyard for genoa staysail • The mast comes standard with an internal hydraulic jack that can be used very effectively for rig adjustments while sailing • The mast base is set up for easy fore and aft adjustment as standard for quick pre-bend tuning • The prepreg carbon mast comes with a regatta join so it can be transported in two sections • Twin spreaders are prepreg carbon • The boom is prepreg carbon • The boom comes with two reef lines as standard • Pit layout set up with all halyards and tack line exits on starboard side, optional halyards and tack lines exit on port side • Tack line can be set up as 2-to-1 as standard for furling FRO • The bow pole can be removed from a socket in the bow for docking by simply releasing a purchase on the tack line below deck • Larger sliding composite foredeck hatch now on center line • The jib-tack cunningham leads aft under deck to the starboard side pit area • Jib in-haul and jib up/down purchases concealed below deck in water tight compartment, the tail of these purchases is led aft to the jib trimmer and can be adjusted from either windward or leeward side • Jib sheet can be trimmed to windward or leeward • The main trimmer has the outhaul, cunningham, mainsheet fine tune, and traveler at his finger tips • The vang leads belowdeck in a watertight compartment and exits aft of the traveler • Spinnaker sheets now form tulip sheaves mounted near the transom under deck through watertight tubes and exit through the cockpit side to the trimmer on the windward side • Stanchions pulpit and pushpit have been upgraded to carbon fiber aerofoil as standard
