Enigma XK was built in 1988 as Norna, a tough Scottish Fisheries Protection Agency patrol vessel. During her government service she patrolled the freezing waters of the North Atlantic for illegal fishing.
She was taken out of service in 2010 and has been converted by the Atlantic Refit Centre into an explorer yacht. The vessel was in good condition and so designer Philippe Briand chose to keep most of the original boat, including the original funnel.
Enigma XK has a range of 12,000 nautical miles and completed a season in Antarctica in 2015.
