the lesser of:

The breaking strength of the fender line.

The righting moment of the boat with some inertia factor thrown in.

The force necessary to shread or collapse the fender and pull it out.

Either of these is likely to be well in excess of the strain you would like

seen it happen.

Just because lifelines don't fail when subjected to common abuse doesn't

I don't like being laughed at. Clove hitches rule.

I don't typically use clove hitches for fender lines. Any up/down
motion
with a fender against a dock will loosen them. A cow hitch might be
better,
but it could still come undone fairly easily, as KLC says (and the
1/2
hitch
would add security). Why not use just an RT with two half-hitches?
More
secure, tightens under load?

Add a half hitch or two.

Yep... of course then I'm not sure the point of the clove hitch part. A
round turn is easier to untie in a hurry (though barely).

Loop over the lifeline or rail then tie a prusik back onto the line.
Cost: nearly zero.



I think it's a very bad idea to put a fender line over a lifeline or rail.
Neither is designed for the potential loads. Cost: new lifelines or rails.

I guess you've never had a fender get caught slightly under the dock next to
the boat. It's going to be way more than 200 lbs worth of pull when the boat
moves and the fenders can't.

The strongest direction for life lines is downward force, which is
what happens of a fender gets caught under a dock. The weakest is the
sideways force of someone being thrown against them. They are also
somewhat sacrificial in nature. In a contest between my fenders and
the righting moment forces of the boat, I'm pretty confident that the
fender whips would part long before the lifelines got anywhere near
the failure point. For that matter, the finger of my floating dock
could probably be lifted until either the fender whip failed or the
fender came free, without breaking the lifelines.


Where do you get this? A fender, caught under a dock will tear the lifeline
right off the boat. In fact, it'll collapse the entire side. I've seen this
happen. Why would you want to sacrifice $100s worth of lifeline instead of
tying the fender line to a proper spot... In addition, the daily stress of
the lifelines being moved back and forth with the fender that is rubbing
will degrade the lines and the "whip" will certainly fail sooner rather than
later.

For that matter, a couple of weeks ago, my wife lost her grip on a
fender (clipped to the lifeline) as she was putting it over the side.
The plastic clip holding the fender gave it's life and we had to go
back and retrieve the fender. I don't think the lifeline even noticed.

Once time does not make for constant stress...

A 200 pound person being thrown against the lifelines exerts a heck of
a lot more than 200 pounds of force, and in the direction where the
stanchions are weakest. I have had fenders get caught, and there are
several things that will surrender before the lifelines when it
happens.




Perhaps, but you were talking about the whips breaking. Stanchions are not
going to compress into the deck, but they may get pulled to one side
including fore/aft if a lifeline is depressed even by a 200 lb person.
Perhaps it's not going to be an issue if one is smart enough to have
sacrificial plastic on the end of the fender line, but a lot of people just
do a clove or round turn around the lifeline. Thus, no plastic to break,
just severely depressing the lifeline, bending the stanchion, etc.

Wife is way smarter than any of you.

Got tired of lashing the fenders to the lifelines, having to adjust them
and all that. She got some bronze snap shackles, the kind that have an
eye at one end and a spring-loaded keeper (what is that thing called?)
at the hook end. Tied them to the approporiate fenders at the right
height. They snap right on to the bales at the bases of the stanchions.
The bronze is strong but not so strong that it will carry away the
stanchions if they get caught. They break. The shackles also work great
for fender stowage. A length of line secured to the pushpit. Just snap
the shackles to the line.

By the way, we have never, ever actually bought a fender. We find them
floating in the water and have more than we can use.



Along with stanchions and lifelines? LOL You could make a boat from all the
things found floating or nearly floating.

Then I guess it boils down to the fact that it's perfectly fine to
hang your fenders from the lifelines, as long as you do it correctly.

It's so funny watching people try to use these things.

I can pull out and place a half-dozen fenders before they get the first
one sorted out.

Why do you need a half dozen fenders on a 28 foot boat? I think we can all
have
a good laugh about that, Jere. :')

Ahhh, you caught that ;-)

Often, we're in the middle of a raft-up. We carry 10, just in case, as
our raft-mates can be 15-55', power or sail, with varying skill-levels.
When in doubt, I carpet the side of the boat. I also tend to be the one
throwing the lines and warping them in, as few have 60' "dock lines"
(old sheets), nor can they toss what they have more than about 10'.
