1200 All is good. Dutch couple helped us get off pontoon though we could not turn her into the wind from sideways on so after some strong reversing we went further into the marina where we could drive forward through the wind and turning to starboard with reverse and bow thruster she comes round in her own length ... which is good as we only had a metre spare fore and aft. We tied up outside the lock and waited 15 mins for it to open, processed in with 8 other yachts and large motor boat, tied up using the recessed bollards (bow thruster useful again to get to the wall because you can't throw a line over these).
1400 I could kiss the helpful Dutch couple because as they motored slowly past us up the 13nm Noordzeekanaal he shouted to us to telephone Amsterdam Marina to book a place. We did which took all the stress out of the journey knowing there would be somewhere good to tie up. And here we are in berth Q5 not too far from the facilities (unlike Ijmuiden which was a 10 minute walk along endless pontoons). L brought us in very gently & quietly.
