Re: Jacklines

Danny and Yvonne SIMMS

Hi Dave, it is an issue I have always had front of mind. And as I have said elsewhere, being towed at 8 knots survival is at most a matter of minutes. If someone has a solution  with a new design great. This thread is very important in that it should raise awareness that a harness, tether and lifejacket are not lifesavers if you fall overboard unnoticed and the boat is not stopped immediately. .

Hi Rob and All,   

Tangential to the jackline discussion I would encourage folks to look at the Team O backtow lifejackets.  Really seems to me all lifejackets should incorporate this feature.  
It’s a small startup company with a great idea so they are still ramping up production but I have found them to be very responsive to inquiries.   
They did studies with strong people being towed at various speeds in a deployed inflatable lifejacket and I believe the consensus was that at greater than something on the order of two or three knots boat speed breathing was so difficult that people would rather have been without a lifejacket at all.  Being towed on their back completely alleviated this problem.  Brilliant.

Hi Rob,
I have two sets. Both webbing. The first runs from the cleat on top of the windlass down both sides over all sheets etc to the big stern cleats either side.
The second one goes, again from the cleat on the windlass down the center of the boat either side of the mast to the ring on the deck in front of the windscreen.
I concur with you that to go overboard tethered with the boat doing my average of 8 knots would be lethal. Particularly if the off watch is asleep. .
Reality, to have a practical way of tethering that will prevent you falling over in any circumstance when WORKING on deck is in practical terms all but impossible. Dual tethers help, one short, one long. 
I have a few  cast iron rules off shore based on this truth.
Tethered or not, go overboard and you are dead unless you are very lucky
Whatever the weather if you leave the cabin you are harnessed and tethered always even sitting in the cockpit. 
Never leave the cockpit without attaching the tether to the jack lines first.   Never go on deck at night unless the off watch crew is roused and has sight of you. Day or night off watch crew should be aware every time you go on deck. 
If some one goes overboard, tethered or not, Stop the boat as fast as you can, Swing head to wind
Kind regards

Hey Team. 

I would like some feedback from members who have installed jacklines to their Amel. We intend to fit some to Jaygo and have high quality webbing for the job. (Reason for webbing: Strong. No roll hazard. Some stretch to absorb shock loads.  UV protected). 

Ideally I want the configuration to prevent clipped on crew from going over the side in the first place, not just retaining them tethered to the boat after going over. This reasoning is the result of personal experience in foul weather as well as that of a friend who was washed overboard in a Sydney/Hobart race and almost drowned while being hauled back onto the boat. As Dee and I almost always sail just as a couple, I acknowledge that one person trying to help the other back on board in really foul weather weather would be nigh on impossible. 

What ideas do you have on where to run and affix the lines?
