In a recently published official Report from the Swedish Government (SOU 2010:73) a leg- islative proposal has been introduced. Its main purpose is to prevent parallel registrations of ships that are bareboat chartered to other countries. The legislative proposal claims that by preventing parallel registration of ships the Swedish Maritime Code will better corre- spond with the UN convention on the law of the sea.The UN convention on the law of the sea clearly states that ships are forbidden to fly two flags. There is however no restriction concerning parallel registration, simultaneously, in two registers. A ship that is bareboat chartered out from Sweden does not fulfil criteria re- quired in order to be deregistered, according to the Swedish maritime code.
