Help with replacing outhaul

[robertsapp]

The outhaul on my '95 H336 is badly worn and needs to be replaced. It's internal to the boom and I'm pretty sure it has a 2:1 purchase, which means that there is a block of some sort inside the boom. How exactly does one go about replacing this assembly? Does it require disassembly of the boom or can it be done in place? Any advice would be much appreciated.

Hi Robert, not sure about the H336, but have done this on other yachts - my method is to join the new rope to the old rope (butt to butt) using whipping twine, needle and a sailor's palm. Unshackle the old outhaul from the clew of the mainsail, and then pull the new rope through the same path as the old rope, and attach to the clew as before. Hope this helps.

Appreciate the tip, but I don't think it's going to work in this case. The line that attaches to the clew of the sail is not the same one that exits the boom at the mast. There's a 2:1 block arrangement inside the boom. One of the lines is attached to the block, and the other runs through it with one end attached to an anchor point inside the boom.

I'm need to do the same thing on my '93 H-28 but, while I could replace just the outhaul (or reefing line) as described above, over the weekend my sailmaker said I can remove the cap on the end (clew end) of the boom and remove the outhaul, reefing line and related blocks in order to replace them, recommending that I replace the blocks, too, as Hunter did not use (in his opinion) very good ones (my outhaul does jam when I try to adjust it), plus I can then run a 2nd reefing line as well (Hunter's mainsails typically come with two reef points but only one reefing line). Have not attempted this, yet, and you may be able to tell me how easy or hard a project it proves to be before I have a chance to try it !!!!

I broke the block that was inside the boom and had to replace it a couple months ago.

Drill out the rivets and the "cap" comes off. Get a rivet gun and re-do once finished. Not a big deal. Rivet gun is cheap as are the rivets.

Jared is right on for the repair. The boom on our Hunter had already had the ends off because they had used screws instead of rivets. The blocks needed to repair your boom can be had at WM or possibly at the store on this site. Lub all the blocks you do not change out with dry graphite or McLube.
It is so easy to take the ends off that I wouldn't try fish lining it.

On my 33.5 the end of the boom is open. I was able to pull the blocks to the end of the boom after clearing out the birds nest and then re reeve the lines. As was previously posted you will need to join the new line with the old by sewing them together and then pulling back thru. It sounds complicated but if you have the blocks visible it becomes pretty clear
