I went to the rock climbing store (that just happens to be next to
West Marine up here) and lucked into meeting a clerk who used to do a
lot of sailing so could offer some interesting perspective.

Rock climbers expect to fall and put their full weight on their gear
over and over. If their gear breaks, they don’t just fall in the water
They secure their carbiners and turn the locking nuts with one hand
all the time while they hang onto something else with the other. This
gear is designed for more critical applications than safety harnesses
on boats which are usually just back up.

I tried single handing a carbiner and then shuttled across the parking
lot to do the same with a Wichard double action shackle. I found the
carbiner a bit easier although cold hands might tip the scales a bit
in the Wichard direction. The carbiner develops full strength even if
the locking nut isn’t turned and has considerable strength even when
open. The idea of that light smooth aluminum fitting running on
jacklines and other gear was a lot more appealing than the flat metal
Wichard or even a heavier S.S. snap shackle. Cost aside, I found the
carbiner something I preferred and trusted just as much. And, at eight
bucks and change…

I did decide on snap shackles for the harness end in case they need to
be released under load and because they are smaller and more compact.

Couple this with a length of the bungee elastic they use in bungee jumping
and you will find yourself back on board so quickly you won't even be wet.

You might want to spray the locking bit of your biner with T-9 (my
favorite) or sail cote before you use it. Wash the beast with fresh
water as often as you can and replace when the mechanism becomes fouled
with oxidization... Otherwise, if you like the way it works it may
encourage you to use the thing and that has to be good. I'm terrible
about hooking in, but it is the right thing to do.
