Claimants take advantage of the action "in rem", rather action "in personam", because an action "in rem" is more easy and convenient to institute. It is more difficult, in an action "in personam", to summon the defendant via writ outside the jurisdiction unless the defendant is a resident of EU or EFTA countries. Besides, the processes to find the rightful shipowner, the defendant, are very complicated and time consuming due to the complex and inconsistent ship registration in different countries. An action with respect to a bareboat ship will frequently encounter this problem.
