Much Clearer, thanks.
 

I had some assumptions that were clouding my understanding...

When I make up fiber runners, I make the runner itself from covered HM and put a thimbed eye at each end - I set the length about 3 feet short of the deck when it is lead straight down.

For storage, I take the runner to the rail with a small tackle or a bungie.

When setup , I carabiner on a tail, take it to a turning block and then to a winch.

I was picturing just the part aft/lower from the carabiner, and some how got that very wrong...

Thanks,

Bob
