McConaghy Multihulls


McConaghy released their new line of sailing catamarans in January 2016.  Designed by Jason Ker, the series initially includes 50’, 60’ and 90’ high performance cruising catamarans.

McConaghy and Ker have collaborated for many years on racing and cruising yacht projects. Ker’s experience with BAR Racing (Britain’s America’s Cup Race team) has put them at the very leading edge of multihull design.

Multihull Expertise

McConaghy’s expertise and know-how in lightweight, high strength, composite construction… combined with their existing expertise in multihull builds (140’ Tri Adastra, 60’ MC2, 53’ Banuls Tri) and 45+ years of race boat experience is set to shake up the multihull performance sector.

This is especially true where weight can have a big impact on performance.
