At present there is no Swedish legislation regulating bareboat registration of Swedish ships. However, despite of this absence, shipowners with vessels already registered in the Swedish Vessel Register do not hesitate to take advantage of the positive aspects of bareboat registration by allowing the registration of their ships in another state as well. The fact that there is a lack of legislation in this area has left a legal loophole resulting in Swedish ships being registered in a second state without any regulation providing protection for affected parties such as creditors. In this book, which is based on Ms. Pourmotamed''s master thesis, both the legal basis of ship registration and its functions, as well as the legal aspects of parallel registration of vessels and its consequences, are presented. The aim of this study is to examine the future of dual registration of ships from a Swedish legal perspective.
