I've searched all forums and checked the Tech Tips and find no details on jack line installation onto our boats.

Does anyone have them? If so, in simple terms, how are they installed?

I can see installing a secure pad eye forward, and then a connection of sorts to the base of the mast, but I can't decide how to terminate aft.

I'd appreciate hearing what if anything others have done.

Thanks!

Jerry

This is a project I've thought about a few times but never completed. My idea was to install folding pad-eyes just below the seats in front of the companionway. Then run the jack-line, from there, inside the shrouds to the forward mooring cleats. Hopefully someone has installed them and has a better explanation.

I've thought about this as well. On our C-250, the ends of the traveler have SS eye loops in them. I've thought about running lines from those loops forward to the mast and then on to the cleats. I've been thinking I'd run the port jackline from the starboard side of traveler to the port side of the mast, then to the starboard bow cleat. Opposite run for the starboard side.

So, if you want to go forward on the port side, you clip into the red line that was attached to the starboard side of the traveler & starboard bow cleat and go forward. If you fall to port, you're restrained from starboard side, limiting the distance you can fall to the length of your lanyard plus the stretch in the jacklines (should be made of dacron or something non-stretchy). You're still going to be dangling from your lanyard with your feet in the water. If you fall to starboard, you're restrained by the line going past the mast limiting your fall again.

Having never used jacklines before, I have no idea if this is a sound method of employing them. If you don't mind the hassle of changing your lanyard at the mast, you could simply run the jacklines from the traveler straight to the cleat without going around the mast. Then when you go forward, you have to either go around the mast by going under the boom (not so easy to do on our TR), or clip your secondary lanyard onto the other side of the mast, and then you need to pull the jackline close enough to unclip from it (and it doesn't stretch). Then you can continue forward.

We placed a couple of heavy duty Wichard folding padeyes on the coaming. A 6' tether connected to either of these allows access anywhere in the cockpit and partially down the steps into the cabin. We have another tether attached to the mast step. If we need to go forward we connect our own tether to this mast-base tether.

Here is the padeye:

I think I still have the jackline I made up for my C25. Might find it and sell it. I sewed a loop in some 6000 lb. test flat webbing. Attached the loop to the forward cleat and installed a snap release on a small loop on the other end which attached to a padeye...

Worked great! On a boat this small, two jacklines are not necessary.

Jacklines should be flat and made up as tight as possible. My current vessels jacklines have to be wet before I can take them off. The padeye should be backed. A cleat will work in a pinch.

For the forward attachment point, you might be able to put a shackle in a hole in the stem fitting in which to attach the jack line.

I like this approach. These boats aren't that big, a careful crawl 2-3 steps and you're at the base of the mast.

I have the PFD with harness; haven't bought the tether yet. This will be a MUST for single handing. I can't have my boat (and dog!) sailing away from me.

And they get away fast. My 16 ft daysailor took off from the beach one day and I had one heckuva time paddling out on my son's paddleboard trying to catch it. Good thing she capsized because she was heading straight out to sea!

I have a jackline(single) that I tie up to bow cleat then wrap around mast 3 or 4 times and bring back to opposite side stern cleat. I have a harness on my life vest. I did one only to keep me in the middle of the boat which is the whole idea of not falling off the side, which I my eye would increase if I had two lines. I do not feel our size boat requires 2. Just my opinion.

A gift of a jack line earlier this year prompted the need for a teather. Just received it from marinepartdepot. [:-)]

Paul, I am glad to see you are still using MPD. They just added tethers at a great price. Glad you took advantage.

Do any of you lake inland sailors use a jack line(s) when you single hand?

We have installed an attachment point for our PFD's (with D rings) near the starboard quarterberth porthole (the attachment is backed up with a plate) so in bad weather (We sail Lake Erie) and storms also waterspouts come fast, we can put the hatch boards in and tether to the attachment point. If needing to enter the cabin we are able to remove the hatchboards-stay tethered in until we are down in the cabin-or clip in before leaving the cabin. I would like to get a jack line from MPD just dont know what to look under..
Because Lake Erie is shallow (as compared to the other Great Lakes),Storms come quick so we must be watchful.

I've decided to keep the jack line along the center...using nylon webbing and a bridle between the forward cleats, then running back to the mast, take a wrap, and then aft to a bridle between the aft cleats. I do coastal sailing, never more than a few miles off shore and always in basically high traffic areas, and will not be going out into unknown weather conditions. I consider this an adequate system for the probable conditions I may encounter.

I'd love to see photos of some of these setups. How do they affect access in the cockpit and through the companionway?
