Re: Replacement of vinyl lifelines

50F water is more than a hypothermia problem. Once it gets down into the 50's, the cold water shock alone has been known to cause coronaries (heart stoppage) especially if you are already pushing 50 or older.

It takes a little longer before the chest muscles go numb and you stop breathing, but if the cold shock stops your heart--you're in trouble that much sooner.

What do you mean by soft? Are you referring to reaming the holes so they don't chafe?

They found that most cold water deaths are from drowning. When you hit the water the cold makes you gasp, inhaling a big gulp of seawater, instantly, which starts the drowning proccess, from which you dont recover.

However, I find lifelines to be fairly useless safety devices anyway. We stay in the cockpit and/or clip in.

Lifelines are great clothes lines and rail meat organizers.
My 34 inches of the deck, solid lifelines, are anything but useless. Only uselessly designed lifelines are useless. Simple solution. Design them properly, and high enough, so they are not useless. Being above my centre of gravity, I havent even come close to falling over them, in decades of full time, single handed cruising.
I always use stainless pipe , or boiler tubing, for my top lifeline, and 1/4 inch 1x19 stainless rigging wire for the intermediate. With the top and bottom of stanchions thus fully supported, the load on the bases is drastically reduced.
I'd never go back to wire top lifelines.

I hear you. However, if you have pipe on the top, you don't have a lifeline. Do you.

Nope, you have ugly railings. I'll take my chances with lifelines.

Sorry I wasn't clear. Yes I was referring to ensuring the holes are smooth, and where necessary installing sleaves so there are no burrs to cut the line. Other than some very old ones where the holes for the wire were just drilled into the tube (this is a terrible idea btw regardless of material) I haven't seen any that took more than a few minutes of work with an emry board to knock off a nick here and there.

Not quite sure what you mean there unless it should read injuries of work which are the units I use to measure the size of my personal projects.

Re: Replacement of vinyl lifelines

Thanks again for all the impute, I think I will hold off for the time being. I do thing they are a bit saggy. I don't see much in the way of rust. Mine are coated with the white covering. There are no turn buckles. There is only one clip at the stern on both sides to take it loose. That hook is were you would tighten it up. It has no room left to tighten at this point. I will try to post a photo.
Notice the small rust spot on both sides of the sheet on the lower lifeline/

That indicates a break in the covering and the rust is coming from the internal wire.

Don't trust them.
