We have the Sure-Loc 76000:01 ladder catches mounted in 4 different places on the boat.
The ladder resides on the stern most of the time as a swim/overboard ladder. We bring our bow to the beach (or close) and have catches on the bow to climb down to the beach. There are catches on both port and starboard sides for docking. Not the lowest price option but IMO has the most options, it's sturdy and has hand loops. I step on and off of this ladder, to the dock, when the boat is moving with no problem.
