About McConaghy Boats

Semi-custom

Australian composite boatbuilder founded by John McConaghy in 1967 — maxi race yachts and one-designs, and from its Zhuhai yard in China the semi-custom MC and electric Panther sailing catamarans, the Sapphire, GT, Platinum and Explorer multihulls.

John McConaghy founded the company in 1967 and set out to build skiffs, Tornado and A-class catamarans from materials never before used in boats. In the mid-1970s McConaghy was one of the first to apply prepreg carbon to sailing boat construction, and its first 18-foot prepreg carbon skiff set a benchmark for years. In 1987 it built the first prepreg Nomex-cored maxi yacht, at the time the largest composite structure in the world. In 2000 employees Jono Morris and Mark Evans took over from John McConaghy and his long-time partner Steve Moxham and went on to build some of the most successful maxis — Alfa Romeo took Sydney Hobart line honours in 2002, and Wild Oats XI won line honours from 2005, seven times in all. In 2006 the company opened a shipyard in China, which supported several semi-custom ranges; in 2012 it helped build James Cameron's DEEPSEA CHALLENGER submersible, and in 2014 it delivered the 42.5-metre trimaran Adastra from Zhuhai, its largest build. Hong Kong-based Tiger Group Investments invested in 2014. The first McConaghy catamaran was launched in February 2018. By 2020 the company, privately owned by Mark Evans and Tiger Group, had tripled in a decade to more than 200 staff in Australia, China and Hong Kong; it was chosen to build the AC40 for the 37th America's Cup in 2022 and a hydrogen chase boat in 2023.
