[Public-List] Life lines

Not far enough to lever the fittings out of the deck, but far enough to
compress the core, seperate any epoxy plugs from the fibreglass
(remember that epoxy and polyester don't bond chemically) so that
moisture can get in, and generally increase the need for tedious,
stinky, maintenance work that stands a good chance of still being on the
"jobs I'm trying to avoid for now" list when the lifelines are actually
needed as a safety device.
Even with fender washers and/or backing plates, compare the length of
the stanchion to the width of its contact area with the deck. Now
remember that that ratio basically describes the effectiveness of the
lever with which you're turning the force of your leaning into
compression on the deck (on Candy Cane, it's about 20:1).
Anyone who leans on my lifelines or stanchions gets one warning, and
after that their name goes on a list of People Who Will Help Me Recore
The Deck This Winter. I've never had to put anyone on that list.
Cheers,
Kris

Think about it - a couple of pieces of 1" tubing isn't going to save you. You need tension in the cable to transfer the impact to the pulpits and their anchors.

They need to offer some level of assurance or they shouldn't be on a sailboat, particularly one as capable as an Alberg. Would I go offshore, basically alone on deck without a harness, probably not - my wife makes me wear one when I go singlehanded cruising in Round Bay but that's me. In my racing days EVERY boat I sailed on we used the lifelines to lean on to read the tails from the leeward side, and yes, in alotta cases the spongy cushy things were there, or we'd stand on the top lifeline to adjust the pole or leechline...tell me you've never done this??? I still lean on mine all the time. Personally, if my lifelines were to the point of the stanchion bases yanking out of the deck if I even looked escance at them, I'd be backing them up with fender washers, more glass or whatever. Crappy stuff like that belongs on a powerboat or better yet, a Yugo.
