After one hour under enginepower passing through Antwerpen, we approached Callorlocks.Due to passage of a large Swedish ship coming from Vrasendock,we had to wait outside the lock for an hour.Our FD securitynumber was accepted when calling Callorlock on the VHF,and the passage through the lock went smooth.Once inside,we kept on for 10-15 minutes before we saw Amstelgracht in Vrasendock.We arrived longside at 16.40,10 minutes after our E.T.A.There was one yacht under loading before us,so we waited for almost 2 hours before we were contacted by Sean Lines the loading master,who ordered us to make a starboard landing.It was now dark and rather windy,so the landing along Amstelgracht was tricky.Once tied up we were assisted by Sean with crew,and a diver beneath to assist with placement of the liftingstraps.
