The first McConaghy MC31 will be sailing in Sydney in november

The first McConaghy MC31 One Design  will be sailing in Sydney in November with Boats 2 & 3 heading to foiling moth world champion Rohan Veal from 38 South in Melbourne and his clients soon after. Boat 4 is also coming to Sydney with 5 & 6 heading to Newport USA.


The design and specification of the McConaghy MC31 has matured over the past few months with input and development coming from a range of sources.

The hull shape and balance of the sail plan and foils has continued to be  refined by Naval Architect Harry Dunning right up until the time the CNC robots started cutting the moulds.


The rig plan and deck layout have been developed with the help of North Sails and Southern Spars and with input from the pro sailors who crew the MC38’s and our representatives, Rohan, Collin and Andrew.

The most obvious recent developments to the McConaghy MC31 rig and deck layout are:
