My 84 already has internal halyards.
They exit through a block at the base of the mast then to a set of deck
organizers.

Depends on if you are wanting to run the halyards back to the cockpit (
like here http://www.catalina27.org/images/Deck1.jpg ) or just want to
run them to a winch at the mast.
If you would like some pics, i can take some this Wednesday.

Joe,
I'm a bit confused by your post. Exit blocks are normally positioned
near the base of a mast where the line bends 90° as it is being routed
out from the mast to a to a deck organizer and then back to line
organizers and a winch. That is typically a factory installation
requiring welded bosses to mount the blocks and not a do it yourself
kind of install. Our C270 (as an example of Catalina's most recent
thinking) does not use any exit blocks. The halyards exit, as you
suggest, several feet up the mast and run external to blocks shackled
to a mast base plate which turns them from vertical to horizontal and
also allows them to sweep aft at a 45° to the deck organizers.
I see Judy pointed you in the right direction by suggesting what you
need is an exit plate not an exit block. The factory solution on my
C270 mast is a series of long slots (one for each halyard) with no
exit plates. The slots are just carefully de-burred and rounded to
leave a nice smooth edge. If you like I can get you the slot
dimensions and there heights off the deck later today. I believe
there's a stagger pattern to their position as to not weaken the spare.

*Subject:* [IC27A] Exit Blocks and in the mast halyards Halyards
I replaced my standing rigging on my 1984 C27 and decided while the
mast was down to update and change the halyards to interior and cut in
two exit blocks. The block for the mainsail is placed about 6 1/2 feet
off the deck, so I could expose the halyard for for deck to be able to
help to raise and lower the main sail.
The problem/question is do I cut out more of the mast below the block
so the line exiting the block is not rubbing/cutting as it heads from
the block to the base of the mast. Is there a piece of hardware that
smooths the transistion or do you just file a smooth path down the mast?
Thanks for your help.
