Jacklines

Post by mashenden »

I recently realized that a bundle of webbing that came with my boat is a jackline system. A good thing to discover before I tackle any notable journeys or experience a storm.

The bundle included two tethers that appear to be usable but I am not sure exactly how. I figure the bronze pelican clips are what attach to the jacklines, leaving the other ends to attach to my harness. A quantity of two tethers so one can attach to the new side before releasing from the other. So far it seems intuitive.

But then there is another loop of webbing on each tether, as shown in the pic below. Each loop can travel along the tether.

Does anyone have an understanding on how the tethers are supposed to attach to the harness? I get that I would need some sort of carabiner to attach the tethers to the harness, but how are the additional loops supposed to be used?

I think if you're going to use the Jack lines you'd want pfds with the rings to hook the harness. Buy a harness from a place like West with the three foot and six foot straps and get them elastic so you don't trip over the six foot leg.

Matt:

From your photo, it looks like your tethers are old. You may want to consider purchasing a more modern updated tether system.

It is important that the end of the tether that attaches to your harness have a quick release mechanism. I will try to attach a photo of a current Wichard tether. The end with the yellow hook portion attaches to the jackline; the other end of the tether with the pull cord attaches to your harness. If you are swept overboard and cannot reboard (crawl back aboard) instead of being dragged along by your sailboat until you drown you can pull the cord (it will be near your chest/waist) and be released from the tether/jackline. You can then float comfortably with your PFD until another sailboat comes along with a bevy of pretty girls in bikinis chilling some margaritas. :D :wink:

From your photo I am not sure your current tether allows you to quickly disconnect from your tether. Also, the tether and jackline material may be structurally degraded from years of storage and/or exposure to weather. You may want to buy a new jack line and tether system.

If you buy a new tether I recommend one that has a short and a long tether combination. Photo attached. This will allow you to always be tethered to the jack line as you move about.

If you should encounter that bevy of pretty girls in bikinis on a Cape Dory sailboat tell them "Roberto says buongiorno". I miss them. :(

Matt:

One additional thought. I would not recommend a carabiner to attach a tether to your harness. Carabiners are not "quick release". You want a snap shackle that is quick release - quick pull of the cord and it fully opens. Most, if not all, tethers sold today now come with a quick release snap shackle.

To put it a bit harshly, the first thing you want to do if you are going to rely on this safety gear is to get rid of this stuff. Start from scratch with new webbing, a proper harness, and proper connections. The web is full of specifics, so no need to go into additional detail.

For drill here are a few photos of a system refined over several decades that (1) prevents shackles and related gear from destroying the deck, (2) allows complete fore-and-aft movement without hangup, and (3) keeps you on the boat where you belong:

Good advice. That stuff should be discarded so neither you nor anyone else makes use of it. I can't imagine someone set that up for use as a jackline system. I'm hoping you are mistaken.

I second the counsel to start with new stuff if this material has any sort of long term mold and mildew or any fraying signs. The real killer for this material is UV too. Stored properly, nylon or polyester webbing will last for years. I still have climbing items from the '90's that I would trust. But if you don't know the history of it, then it is suspect.

I set up jack lines and testers from climbing materials, carribiners, webbing etc. so a little different than the true sailing stuff but the same purpose: Keeping me attached to the boat. I use them whenever sailing any sort of passage or night time/solo work. The West Marine stuff is pretty expensive. You can set up a similar system from a climbing perspective for much less money - but it would not have some features you might consider pretty key. I would like to improve my system with a snap shackle for the tether to harness link for example. However, I believe having a strong, lightweight aluminum carribiner works well for a simple tether to jackline link. But I am an old climber so it works for me. I also use some of this gear to go up the mast safely.

A system for staying attached to the boat is something you really want if doing any sort of passage or you are in a big seaway. I would consider your sailing plans and think how best to piece one together. To us CD'ers, I think this sort of planning is actually fun.

Thank you all for the concern and advice.

The jacklines have not seen the light of day - the webbing is as strong as it needs to be and more. I am confident that they would hold me as well as the bevy of pretty girls in bikinis should we all fall overboard at the same time. I will let them know Roberto says 'ello :wink:

I have decided to buy a new tether in the not too distant future. I definitely see the need for a quick disconnect.

Hello all. Good suggestions.
I would like to throw out a couple of pertinent tidbits.
Our safty harness and tether systems are a variation of standard professional serious fall protection which in the construction industry has raised its ugly head, particularly in the nuclear power business, because so many have died trying to cut corners in the requirements. We would hate to see that happen here. Several things they drilled into us users during yearly requalifications in the nuk business, aside from actually wearing it are:
Plan for a fall, but design to prevent it.
The chest harness design is a key component.
In our case, utilize all hardware rated 5000 pounds or greater, or as per latest coast guard recommendations.
Always have a short and long lanyard, attached at the chest area, not at the waist, so if you do fall, you are caught with your head up, and not snapping your back.
A parallel short lanyard should be used when ever possible at a working station such as at the mast.
Set up your straps and lanyard so you can not fall 6 ft from a safe location. In our case that means when you set up your tether, plan for that 6 ft to keep you in or on the boat.
If you get your system wet, make sure it gets washed in mild soapy water and dried, out of the sun. UV and mildew is destructive and reduce your ratings.
Never allow your life saving harness to mold or mildew in a dark damp locker, which will degrade the materials.
Discard and replace any old style self mousing or slide-closed latching systems which may self release, or hard to release.
Assume you will go into over the side, and plan to prevent it.
I personally also recommend carrying a mirror signaling device, a knife, and some sealed miniature signal flares with my self inflating life vest.

Bear in mind that if you are improvising your own system, the material you use might have a lot more stretch in it than you realize. Six feet could become eight. Or as my late brother-in-law found out, 20 feet might become 25! Keep that tether short.

Bob and Paul:
What are your thoughts about a PFD/harness combination, such as the Mustang PFD HIT 3184 :?: When wearing it under normal conditions the "harness" portion of the PFD is across my waist. If a tether were attached and pulled (i.e. falling down/over) the harness portion would (should) ride up to near chest level.

Thoughts Bob and Paul :?:

Thanks. Matt, this is a great thread you started :!: Much appreciated and very educational :!: :D

I have an self inflating vest with a harness built in. I wear it close to home only. Offshore I wear a dedicated harness only. If I become separated from the boat offshore I'd rather drown than be nibbled to death. Of course this is only applicable to those who are alone.

Jim:

First, I echo the thoughts of others who have posted on your "Bermuda Again" thread. Glad you are back in port safe.

I understand your reasoning of wearing a harness but not a PFD. My view is different.

I have frequently partially plagiarized a quotation from Winston Churchill:

"Never give up, never quit, never surrender; NEVER NEVER NEVER."

I am also fond of a quote from a real American hero:

"You are NEVER out of the fight."

If, God forbid, I ever find myself in such a situation (unlikely given my self-imposed sailing parameters) I plan to do everything I can to stay afloat and alive so I can be rescued by those bikini-clad girls with chilled Margaritas. :D :wink: Part of my "plan" involves repeating the above two phrases (my "mantra") for as long as it takes to be rescued.

On a much happier note: A HAPPY FATHER'S DAY TO ALL DADS EVERYWHERE INCLUDING THOSE SERVING IN FAR OFF LANDS AND SEAS. :!: :D

Roberto,

I think that's the Mustang PFD/harnesses I bought. I also bought and have attached to them some strobes so that the girls in the bikinis can spot me if I fall overboard at night.

Those look like very good products to me and are better than mine (and my first mate) which I use for local purposes inshore. I might trade up if I were doing anything serious.
I did look at their other products and notee there are several recall notice for some of the mentioned products, which you can search for and look up in the consumer product listing as follows:

http://www.mustangsurvival.com/recreati ... country=25

Step 6: if your CO2 cylinder is marked with LOT# 404121 or 404122 please contact
our customer service group immediately at 1-800-526-0532 for further
instructions and to arrange for a replacement inflator assembly. If your CO2
cylinder is not marked with LOT#404121 or 404122, it is OK and you can repack
your PFD for use.

If you are purchasing one from Defender you might make sure you do not get one with the recall, or maybe order from the factory.
I like the idea of the hydrostatic (pressure) function which will not inflate until it gets at least 4" water pressure.

The strobe, daytime signalling mirror, rigging knife, all on lanyards in pockets, and flares are good ideas if you are travelling solo, with or without a short crew off shore. I carry as much in my winter foul weather gear, but since I do not sail or work in cold water offshore anymore I seldom use it.
