Re: Back stay boom supporter broke - now what?
I also feel that the pigtail can be unsafe. If you forget to release it when sailing then you can be in a tough situation when you try to trim for a beam reach and find that the boom isn't moving anywhere. Trying to clip the pigtail in before dropping the main can also be a harrowing experience in 20mph or higher winds.
Double braid is quite a bit cheaper, but when you are talking about the difference between $11 (30' of Samson LS) and $15 (30' of 1/8" Samson AS-78) it hardly seems important. The choice of a block ($15) or thimble ($2?) is independent, and I do like the thimble as an inexpensive and light solution. The dyneema solution will require splicing, but 12-strand eye splices are very easy to learn.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
