Re: Life Lines? West marine and crimp?
I just got a chance to read the articles you posted. While I generally agree with the one from PS, the article from the Rigging Company is a little prejudice in my opinion. It may be because they have a vested intered in wire lifelines, but typical installed cost for dyneema lifelines are generally much less than for wire.
Generally, though not always, dyneema lifelines are installed with no hardware, or at most one gate at either end. When designed this way a dyneema lifeline system will run about $120 for a 30' boat. With each gate adding about $150. This is because the cost of the fittings far exceed the rest of the cost of materials.
My typical lifeline instal is nothing more than an eye splice on one end that is ring hitched to the front bowsprit, and an eye splice with a sailmakers thimble at the other end. I do tend to oversize the line just because I think it is more comfortable, so my worksheet looks like:
1) leingth of lifeline plus 3' (extra for splicing) * $1.25 (cost of the line)
2) plus $6.00 (cost of the thimble)
3) plus 5' * $.40 (cost of lashing line)
I should point out that I do not install these professionally and don't work as a rigger. I have just swapped over a number of friends boats, and my own to dyneema.
