I am going to replace my boom topping lift over winter. The cover is completely worn away where it goes through the block at the end of the boom. Some day maybe I'll go with a rigid vang, but for now I'm contemplating going to a high-tech 12 strand rope to replace the ~40 foot wire and ~20 foot rope tail. I posted this same question to the Pearson mail list and that was my favorite response. Samson makes a 1/8th inch line that is rated for 1800# and it's only $.15/ft. Has anybody done anything similar?

I have successfully spliced a loop for my topping lift (T/L) and eagerly await spring to try it out. I also learned a lot in the process about splicing Amsteel 1/8" 12 strand line that may be of interest to others. The line is strong (1800# breaking strength) and light. It was also cheap. It was only $.15 a foot from Defender Marine. The only disadvantage is that it will be hard on the hands. I think it will be OK for this application but I'll hold on to the outer layer of the original T/L sheet just in case.

I had a hard time finding a fid for 1/8" sheet. I could have bought one but I couldn't see spending the money for what you were buying. I stumbled on a McGyver method using a coathanger and fiber tape that worked really slick (see http://www.berkeleypoint.com/learning/singlebraid.html). I used the coat hangar/fiber tape to feed the tail, but didn't follow the splicing method listed at that site. I followed the splicing instructions listed at the Samson website (see End-for-End Splice for Class 2 12-Strand Ropes at http://www.samsonrope.com/home/recmarine/splicing/index.cfm). To determine fid length, I multiplied sheet diameter by 21.

Once I figured out what I was doing, it took me about 25 minutes from start to finish.

Practical Sailor has mentioned using 'high tech' line for lifelines. After learning how easy it is to splice end loops, I can see doing this in the future. But I'll wait until I see whether my splice holds and how the Amsteel weathers.

A special thanks to the Pearson list and especially Michael Robinson, a professional rigger on the list, who convinced me that a neophyte to rope splicing could tackle this project. Using methods from the first site and instructions from the second site listed above, anybody could do this.
