Friendly rigger gave me an interesting tip. I'm replacing my furling line because is too big for the furling drum,which adds significant friction as it spools and bunches itself up. The tip is to remove the core from the line,which allows the line (now just the outer weave) to lay flat when spooling on the drum and could eliminate the bunching. According to the tip: "the outer shell is where most of the strength is,the core is just for bulk." Furling line isn't under much stress in any case.
Removing the core did decrease the bulk of the line significantly. I might downsize the line eventually.
I just had to replace my furling line also. The old one purchased by the prior owner was to short. So I purchased 60 feet of 1/4 inch line thinking it would be plenty.. It was to short. I then purchased 120 feet of line and it worked. I used the extra 60ft I had purchased for a 6 part purchase on the engine end of the dingy davits:) works great there. It hurt buying the line twice though. In testing it the 1/4 inch seems to be working well. We will see once we have it out sailing and some tension on it. I didn't want to go that small because of the hand grip-ability but the 5/16ths we had there was too big for the spool and we were also having problems with it piling up on the furling drum and seizing up.
At least I hadn't stripped the core:) and could re-purpose my to short piece of line.:)
This tip has actually worked for me right now. By removing the core,the line is now squeezed in the spool and furling works much better than previously. No need to replace the line.
