Actually, when falling right against the anchor with a nonstretch tether, the fall...

While some climbing equipment (eg, dynamic ropes) will fail before, say, the human pelvis is powdered, most carabiners, even the nice wire gate ones which don't freeze up on ice climbs, are going be able to hold a human in any conceivable situation on a boat.

My bigger question would be making sure you had locking carabiners instead, nothing would suck more than going back and forth, dragging the carabiner enough to open the gate, and then falling, to have it fall off.

Of course, if load was an issue, and if you didn't want to be scraping a biner back and forth along your nice cabin top/deck you could make some webbing loops and just clip into those. You'd want to replace them pretty often, but they'd bend so that the load would always be from the correct direction, and they'd be a lot nicer to your decks finish.

Once again, armchair physics/math here, so please don't bet your life on anything I'm saying. Thanks.

factor can far exceed 2. Try a 2' fall on 4' of webbing and see how it feels. Actual, please don't do that. You will be injured.

Yes, the biners on the jackline end must be lockers. It is worth repeating.

I pulled the gate sideways out of a biner once in a modest fall. A bit of rock pressed it sideways. Not on a locker. I knew it was a bad spot and had a backup a few feet away.

At work we have to use fall restraints with clutches that do a nice slow down , the old style would do almost as much dammage as falling

If a dirty bottom slows you down what do you think it does to your boat
