Entering the lock Sovereign Harbour

Leaving Sovereign Harbour Eastbourne for another mooring. Sovereign Harbour was great, now heading off to try out a swing mooring for a year. I may come back if I miss the convenience of it all.
I am sailing solo, planned 6 casual days.
Boat doesn’t steer well when reversing, so I use the ropes to get it started in the right direction when leaving the pontoon.
