...and thus the old sailors term "getting the fid".
As an old Coasty I did a lot of splicing of both single and double braid line. The method above is easy, and makes a good joint. It takes practice to get a thimble installed correctly - not to tight or to loose. Correct measurement is key.
Butt splicing works great, but after continued use the line will get stiff at the braid. In addition to the stitching we also placed a whipping over the ends of the splices. The line repaired with a butt splice were replaced as soon as possible. Back in the early 80's it took a while - we, the USCG were funded in the DOT under the catagory of "other", so $$ was always tight.
I don't know what to say, but God Bless America.
