The 2010 Contest was held in the Canadian town of Midland, Ontario, which had played host to the contest in 1994. This was the first contest in which GB and Northern Ireland competed as separate countries, rather than as the combined UK team that had attended previous editions of Atlantic Challenge. A week of keen racing on the waters of Georgian Bay resulted in GB in Integrite winning Atlantic Challenge for the second time. Skipper Rob Hunt also won his second Atlantic Challenge, having been onboard Integrite in 2004. Northern Ireland in Harmonie finished in third place overall and both GB and Northern Ireland included several of the wider UK crew from the 2008 contest in Finland.
GB Crew: Robert Hunt, Dougie Brown, Ben Heaney, Chloe Hunt, Victoria Hunt, Rachel Innes, Katy Jenkins, Joe John, Lily John, Henry Linscott, Gwen Matthews, Lewis Owen, Lizzie Owen, Camilla Rowe, Stewart Samson, Gavin Sim, Ben Stone, Zoe Williams, Rob Wilson.
