I run a single jackline down the center of the boat.
I have even experimented with wrapping it once around the mast to reduce stretch. If I have to go beyond the mast I clip on forward with my second attachment point before releasing my first and repeat going back. My boat has a 10 ft beam and I use a 5 ft tether going to the mast.
My attachment point on is a cleat at the center of the bow, approx. 24 inches from the rail at it's closest point and I use a 3 ft tether working forward at the bow.
Everyone says the point is to stay on the boat, yet, I regularly see boats set up with two sets of jacklines running down the outboard decks. OK of one is working with a crew. If single handing, it seems to me that it leads to a false sense of security and invitation to go over and get dragged.
Thanks for your reply. As me, I see running the Jackline midline is the only real sensible way to do it, it keeps you on the boat by using your choice of tether length (incorporated into one tether, see original post links), double clipping to the line before removing/changing a tether length etc. It takes foresight, planning and multiple length tethers(all tethers/jacklines "customized" for an individual boat) but, the point is, no need to have a tether long enough that you could be washed overboard. I totally agree with your methods.
The original question was which clip to use on the harness side, yet some replies pointed toward running Jacklines, and as I see it, the wrong way (I was hoping to avoid going here). It (one Jackline) should run mid line for use with a tether, and may use alternate fixed(only if using a Screamer) points eg. near the cockpit. Point here, you may be double clipped in while moving from one line to another attachment site or when changing tether length. I also have the Screamer attached to the main section of tether especially important if clipped into a short length of Jackline or anchor point(again see orig post for screamer use links). Although, it is difficult to talk about either tether related or Jakelines and exclude one or the other. Jacklines should be a separate thread, to keep things simple & to the point.
I have also read of a very experienced sailor who has never met or heard of anyone who had a quick-release undo itself, with the exception of 1 person he knew by his own fault didn't latch it appropriately.
So, some say the major fault with quick-release is human error & others say it can come undone after you have correctly clipped in, eg by catching the lanyard on something. Possibly the correction for "catching" the lanyard is to remove any end handle which is attached to its bitter end. Yet, that could pose problems of finding it during crucial seconds. Again, some say, not catching; but certain maneuvers/pressures/unknowns cause unexplained unanticipated quick release openings.
Now, you either use eg. the Kong Tango(see original post link) or a quick release. The Kong Tango will not open, the quick release could possibly open. If you want to guarantee staying on the deck(varies depending on your Jackline system) you use the Kong Tango with the Spinlock S-Cutter, but this method requires manipulating a cutter in unforseen circumstances but offers you a second chance. There is no second chance if the quick release accidently opened. If your knocked out, none of the discussion applies. I'm now thinking the best choice is a "NON- quick release" for the conscious. No matter, I guess it will always be a crap shoot and boils down to an individuals personal preference influenced by his research into the questions. This post hopefully, will help one to make their decision-
Personally, if single handling, I have to stay on board. I think I would rather make the decision to cut free rather then be accidently let loose no matter how great the odds are against it, I know my luck. If I were sailing the BVI with friends I may favor the quick release, but I wouldn't be harnessed in either in all likelihood. Would I change from one clip to another depending on circumstances, highly unlikely. This thread has helped me make my decision, that being clips similar to the Kong Tango's autolocking snaplinks.
