Was a problem on a valve on the ferry tank, the Pilot was in comms with base via a sat phone for a few hours while they structured a plan in conjunction with coast guard and during that time tried to resolve the valve problem.
Unable to fix diverted close to a cruise ship for the chute pull.
The pilot was apparently in the water for 40 minutes before rescue and I guess on a North Atlantic crossing that could be fatal.
A good outcome under the circumstances
