To use PortToPort Online or the AtoBviaC Web Service, you must first register to create an account. This will grant you a free trial license with a limited number of distance calcuations. In Trial mode, you are restricted to calculating distances between just six ports (Chiba, Copenhagen, LOOP Terminal, Melbourne, Novorossiysk and Port Rashid) and the route editing functionality is disabled.
