Here's the ladder at low tide. It's a bit of a steep climb, but perfectly alright. What makes climbing the ladder at this state of the tide fun is if the wake from a big boat going by rolls Lady Jane some. You definitely get that 'going to tip over' feeling.
The ladder is normally stowed resting up against the wheelhouse roof when it's not in use, so it does not chafe needlessly. The blue rope you see is to retrieve the ladder from the quay.
Here's the ladder at high tide. Lady Jane is floating close up to the quay wall in this picture.
Oddly enough, I find negotiating the ladder at high tide the hardest, as I've not got the courage to walk across it and Lady Jane is often floating away from the quay side, making jumping across pretty 'interesting'.
Oh, and before you ask, that ladder is 3.4m long (10 ft).
