Clive Palmer has said that he is trying to convince up to 1000 cruise ship passengers to board his relaunched Titanic.

The Australian billionaire is attempting to fill hundreds of third class cabins for the ship's maiden commercial voyage from Southampton to New York in 2017, News.com.au reported.

Palmer, who has recreated the world's most famous liner in a shipyard in China, has completed the tanks tests in Denmark and has showed that the ship's cabin designs are well advanced and the fundamentals are robust.

The ship's first class cabins will boast of opulence and hundreds of cabins below the waterline will replicate the cramped quarters of the mainly Irish immigrants who sailed on the doomed maiden voyage.
