I have the first one exactly. It is very easy to use and has never come out or loose. There is a small latch on one side, open the latch and angle the anchor up then slide sideways to get it out of the other side. There is no way it can come loose or slide out without opening the latch. An old soft sided cooler keeps the chain off the deck. If you zoom on the first picture the latch is on the left side. I like it, no issues, or complaints. I have a 155% genoa that stays several feet away, never snagged it yet, not sure why it would ever be in front of the bow pulpit, but I suppose accidents happen.
