Mnay ppl have complained about slapping of halyards and wires inside
their masts and are looking for solutions. Strangely, this has never
bothered me but I may have a solution.

Get several cans of that expanding foam (product name "Great Stuff").
Every 10' or so drill a tiny hole in the mast large enough for the
nozzle to fit. Push the nozzle in far enough to squirt a dab on the
opposite internal mast wall, on the side wall and opposite wall and
withdraw the nozzle to put a little just inside the hole. Allow it to
set. Push the nozzle through the dried foam at the hole till it is
above the four foam spots and inject enough to form a blob filling the
cross section at the mast. It will be held in place by the four
hardened blobs. Let it begin to set but work th halyards up and down
as it sets.

I have not tried this but might if the slap ever bothers me.

Because they and you are bothering them with their slapping noise other
boaters seeking solitude and peace :-)
Especially at night.

Ok...dumb question....
If one of your halyards does break..how would you thread a new one up
through the mast channels?

We have had a boat with 4 internal halyards for 14 seasons, and
chartered others before that. The only way we get slap is if the
outside part is left against the mast, never inside.

Just run your jib and spin halyards forward to the pulpit and the main
halyard to the boom end. The pole lift can go to the base of a
stanchion forward.

We also have internal halyards and we don't have slap per se, but we
do sometimes hear the halyards rattle inside the mast. I don't think
it can be heard off the boat, and it can only be heard on the boat if
it is relatively quiet.

Slap outside is something else, and usually you can see the marks that
whatever is slapping has made on the mast or boom or other part. We
tie our external halyards off on the pinrails except for the jib. We
have a little fender between it and the mast, and we also have it tied
out.

It seems to me someone on this group has actually filled their mast with
styrofoam peanuts. Not me though. If anyone else rembers any details of
this post away. I can't rember if they had internal halyards.

Don't try Parallax's spray foam experiment. You will never be able to keep
the halyards, etc. running free and if you can move them at all afterward
they will be horribly stiff (almost rigid) and very rough. Might work if
your only internal lines are wire and you use a strong solvent to clean the
wire after the foam cures/sets up. Me, I'd try a different solution.
