Jacklinessss
 
Getting my boat ready for a trip, I decided I need jacklines.
Besides, they will give the kids something to clip to when they insist
on sitting on the bow. I decided the ones made from flat webbing
material are not good as I have seen that material degrade very
quickly in sunlight, so I used 3/8 braid. Ajny thoughts on this?

One normally removes the jacklines when not necessary. Never had
jacklines degrade since we only deploy them when needed. Otherwise
they represent a tripping hazard.

My own jacklines are webbing. I see no evidence of degradation. I
take them off when not needed.

I prefer webbing as line can present a hazard when stepped on.

Mine are white webbing. They're only set up when needed. No problems
with degredation so far.

Hmm., flat webbing: terylene/polyester? Nylon? Polypropylene?

3/8 braid. Hmmm, nylon? terylene/polyester? polypropylene?

Still, round braid shows less surface to sunlight, for the same
strength, no matter what.

I have used both braid and webbing jacklines.

Braid are quicker to rig, cheaper, and easier to snap onto with a
double-action caribiner. However they can be hazzardous as they roll
underfoot, and always at the wrong time.

I presently use webbing as its mandatory for some offshore racing. As
they are only rigged when offshore UV degredation is not really an issue.

Incidentally, I rig a single jackstay from the starboard quarter down the
deck inside all shrouds (chainplates are on the outside of topsides) past
the forestay and back to the port quarter. A crew can go down the weather
deck, work anywhere, be foreward of the forestay for a spinacker jibe, and
then return along the new weather deck without any need to unclip and
reclip.

I also have two permanently rigged wire jackstays along each side of the
cockpit. Tethers are attached before crew come up the companionway, which
is a useful safety procedure.

Someone made the point that flat webbing presents less risk
in terms of slipping. After slipping on sheets a few times I can
relate to that. In either case, jacklines should only be deployed
when necessary so long term exposure shouldn;t be an issue.

That's overkill, but if that is your rule that is your decision.

Hmm. My rule is that regardless of wind and sea conditions, nobody goes on
the foredeck underway unless he's clipped to a jack line.

But the jacklines needn't be left out on deck, exposed to the sun,
unless the boat is actually being used - arrange their "installation"
so that they can be easily removed, and stowed below, when the boat is
not in use (and that may encourage you to check them for wear each
time you install them!)

I guess that rules out the parties I've had on my boat where there were
maybe 5-10 people lounging out on the foredeck (under way) at any time
and another 5-10 people milling about the boat. It would have been
steady entertainment for me anyway to have them all clipped to a jack
line, watching them try and untangle themselves over and over.:)

Heavy seas aren't the only cause for a person to go over the side. MOB
drill gets a little easier to accomplish successfully when the MOB is
still attached to the boat. The poster's policy is mine as well and my
1st mate likes it that way too. ;-)

That's why they call you "Skipper". It's his responsibility,
therefore, his call.

I think I just had a Parallax-type idea. What if you had Spectra or
some other "line" type jackline, and then sleeved it in "sacrificial"
lay-flat nylon covers some three to four inches across and maybe
velcroed every foot or so? That would give you the strength and
lightness and stowability of Spectra/Vectran and the lie-flat
attribute of webbing.

Just musing,

R,.

Mine were the same as the lifelines - SS cable covered with vinyl. Were out
all the time. Are not slippery.
