Default Why covered HM?

So the core is exposed from just above the block to the end of the HM.
Then we bury the HM into the Regatta Braid about a foot past the HM cover bury, and whip the Regatta down.
As for sizes, it's whatever Regatta will accept the size HM we use, and of course this is in turn determined by the size of the forestay, and the vectors.
Fair leads,

It sounds like the HM cover is never exposed. The part between the block and the runner is stripped, and the rest if covered by the regatta braid. What purpose does the cover serve? the only benefit I see is increased friction between the hm core and the regatta braid.

Hi again,
I wasn't clear, apparently. The HM is uncovered until just forward of the deck block, and the Regatta Braid extends just past that point. The HM is covered from there up to the tang. Put another way, if you were to look at the runner, starting at the tang, you'd see an eyesplice in covered HM angling down and aft towards deck. A foot or two above deck the covered rope would disappear inside a length of Regatta Braid. Just past where it entered, the cover would be removed. Clearer?
Fair leads,
Brion

Default 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
