Mr Andhoy and three crew members have embarked on an unpermitted voyage to Antarctica's Ross Sea, in defiance of both the Norwegian and New Zealand governments.
A previous trip he made to Antarctica almost a year ago ended in disaster when his yacht Berserk sank in a fierce storm and three men died.
Declaring himself "a Viking", the Norwegian adventurer says he is seeking the wreckage of the Berserk, which was serving as a supply ship for an attempt to reach the South Pole on quad bikes.
New Zealand authorities, who co-ordinated an extensive search and rescue operation last year in which Mr Andhoy and a companion were airlifted to safety, are furious about his return voyage.
Authorities are looking for the Nilaya, which Andhoy has said does not have a locator beacon. It is assumed to not have adequate provisions for an extra expedition member, either. Link -via Arbroath
