Yourself? Was it very difficult?

Thank You.

I saw a bit of discussion in the past when searching, and I've read that, but did anyone rig it?

thanks ...

I rigged internal halyards on my boat this spring. It is not difficult to do. I purchased the internal halyard sheaves and new mast step base plate with the additional holes for blocks from CD. I then purchased two mast exit trim pieces designed to trim out a long narrow rectangular cut in each side of the mast. Halyards exit the cut outs about 6' above the deck. I staggered them a little bit so the integrity of the mast wouldn't be compromised as much. At 6' above the deck, the halyards are easily grabbed externally as well if needed. Changing to this type of halyard setup significantly reduced the friction I was experiencing while raising and lowering the sails.

Cool.. thanks for the post. That sounds like a fun project. I've got my mast plate, so I'll start looking for the other items. I've been staring at the catalogs for the clutches, deck organizers and other stuff for some time now, but I'd only thought of setting up the back to the cabintop halyards externally. It sounds like internal is a better idea.

<center>Retrofitting Internal Halyards</center>I converted my 1979 standard rig to internal halyards myself. It's not real hard. Before cutting holes in any mast, measure twice and think three times. Keep the holes away from the gooseneck area and from each other. I follow the convention of headsail controls to port, mainsail controls to stbd. Finding the correct size masthead sheeves can take a bit of shopping. They're inexpensive enough that I bought a few different sizes/types, then picked the best fit.

In addition to the usual lines lead aft hardware, I added a large plastic cam cleat low on each side of the mast in line with the halyards to temporarily cleat the halyards without going aft to the line clutches. Things are arranged such that when I apply a little halyard tension from the cockpit, the halyards pop out of the cam cleats, transferring control to the clutches. I used 3/8" polyester double braid, but when I replace, I will switch down to 5/16" such as StaSet or Sampson equiv. (Hope I'm getting the spelling close enough to recognize.) Others prefer lighter, higher tech halyards (with higher tech prices). If you want to impress the yacht club racers with your expensive tastes, you could have tapered halyard custom made.

I singlehand a lot, and have been very pleased with my internal halyards and control lines lead aft.

Sweet, That is a useful addition to have the clam cleats so you can set while at the mast. I can remember walking back holding the lines on a previous boat I had. Thanks for the pearl.
I'm looking at running the 5/16 staset to strbrd. as I always start out, and return on a strbrd tack, so I'm putting a lot of thought on the location of the cuts and the smallest through blocks I can find.

I'm also trying to find the deck organizer that is least likely to bite toes. Got to be careful on the small boats, and I love to go barefoot, but I also love my feets to keep working well.

Looking at fast shoes also.

The only part I'm not clear on (that I'm aware of) right now is the divider/spacer at the sheaves, and how many and how wide the sheaves themselves. I've ordered two and bout to order two more. Oh well... better get comfortable dropping that mast alone.

Alum rivets for adding the mast hardware, right?

Thanks for the help.

Ray,

With the masthead sheaves from CD, you won't need anything at the masthead other than the sheaves themselves. Each sheave is wide enough to replace the existing two sheaves and spacer. Depending upon what type of masthead you have, you may need to cut out the aluminum in the center of the base of the masthead to allow for the halyards to go internally. I had to do that, but no big deal.

That Aluminum drills pretty easy I'll bet.. Thanks for the heads up. Looks like I'll need two wide rope sheaves and a look at the exit blocks.

Anyhooo... back to droppin the mast with one hand.
