I had to replace one on my 04 prov but I used a small cabinet latch and ithas worked great! The part on the frame(your third pic)I refer to as the female end is two small rolling pieces of ceramic and the “male” end on the door is a V shaped piece that when closed seperates the two rolling pieces and latches securly. Tension can be adjusted by expanding or pinching the male end. Sorry I can’t take photos as the boat is up north. Works great and only cost a few bucks.
I think for small applications like that latch that non marine items work every bit as well at a fraction of the cost.
