St Peter Line, which operates two cruise ferries in the Baltic out of St Petersburg, has sent a letter to the prime ministers of Sweden, Finland Estonia, Malta and Cyprus to express its concerns about the imopact of new border checks in the EU.

The new rules affect the St Petersburg-Helsinki-Stockholm-Tallinn-Srt Petrsburg service of the compabny’s 38,000 gross ton Princess Anastasia, which flies the flag of Malta.

"The Finnish Border Guards have sent us a letter on 17.2.2012 saying  that as from 1.3.2011 and as of 1.5.2012 some new rigorous border  procedures will take place,” the company that is domiciled in Cyprus but managed from St Petersburg in Russia said in the letter.

“Earlier, external  border checks were carried out only when the vessel was coming in to  EU and Helsinki, as well as when the vessel was leaving EU and going  out from Tallinn. However, these new procedures will force all  passengers (whether EU citizens or not) to external border checks in and  out in all EU ports Helsinki, Stockholm and Tallinn, even if the  ferry is in traffic within EU.”

“This will be so time consuming and  unnecessary within the EU borders that it will in practice destroy  the idea of free movement within Schengen area. We truly fear that  the passengers will not because of the time consuming procedures  have enough time ashore and therefore abandon the possibility to  travel with us. This would certainly mean the closure of the line,” the company said.
