single reef line

[frank and diane]

I sail in San Francisco Bay and I reef frequently. I get a lot of chafe in the single reef line at the aft end of the boom exit box because the reef line chafes on the forward end of the exit box.. Does any body have a fix for this problem? I thought of using a bullet block mounted on a  custom made support, but haven't made it yet.

Hi,  a search on "reefing" finds a reference to the C380 website on this post:  http://c34.org/bbs/index.php?topic=2237.0

I'm not sure if it fits your description, which is a new one to me, since I'm unclear on what you mean by the "boom exit box."

Also, please let us know your hull # and year for additional assistance in responding to your question.  See: http://c34.org/bbs/index.php?topic=1506.0

Thanks,

Some booms have a single sheave at the end of the boom and is used primarily for the outhall like mine on #707 Year 1988. Other lucky skippers have two sheaves that exit the end of the boom( like #1259) and they can carry the internal reefing line. If the line size fits the sheave you should have very little chaffing if you have a newer boat.
That is why Stu tries so hard to get skippers to include the year and hull number. Also, to reduce the effort to reef, I strongly recommend adding a block at the reefing cringle. It reduces the effort to get a good reef. I was very pleasantly surprised when I installed mine.
Good Luck, Dave

I believe that Frank has #1415.  If it has the same boom arrangement as Crew's Nest (#1383), the aft end of the boom has three return blocks – one for the outhaul mounted 4" from the end of the boom, one for the 1st reef and one for the 2nd reef.  The latter two being mounted just inside the end fitting on the boom.

I only have a 1st reef line which passes through the boom, exits around one of the blocks, up through the sails, and then is tied off to the boom through a slot in the foot of the sail. In this arrangement the line does not come in contact with the slot in the boom to chafe.

Is there something that I do not understand here?

While on the subject of reefing.... I have a traditional set-up on my boom for reefing my full-battened main.  I found that in order for the reef points to be secured as tightly (low) as possible to the boom, I have to slide out the first four or so slugs from the mast, otherwise the reef cringle is too high at the gooseneck, causing too much tension on the reef pints along the sail foot.  Has anyone else found this to be the case, and if so, what remedies have you come up with, other than the removal of the sail slugs.

[Jim Price]

Tom, what we don't have is an insert the would fit into the mast track above the boom after the sail is mounted.  The insert would effectively reduce the track width down to the boom thus allowing the slugs to stack at the boom without  falling out.  I have seen something like this for smaller boats but have not seen a "manufactured" insert for our size boats.  Wish someone would make something out of aluminum or stainless that could be bolted on the mast after you put on the sail and leave until sail needs removing.

I just don't have the equipment or time to make something like this.

Jim - there was a discussion about this on the C36 list a little while back. I don't remember if it was on their message board or just on their mailing list. I believe someone had fabricated something from an aluminum door threshold they got at home depot or something.  Maybe Tom Soko will chime in. Catalina Direct has something on their website, but it may just be for C25's.

cool, I was thinking about the same thing the other while reefing the main.

[Tom Glennon]

Yes! That looks like it would be a relatively simple retro-fit... something to keep us busy in the workshop over the winter.  That certainly would be ideal, as it would allow the slugs to slide right down to the goodeneck, rather than be held up by the screw in the mast.  Thanks guys!!
Might be something I could market, and then be able to retire!!   I'll keep you all posted!

[Jim Price]

This is the item Catalina Direct sell for C-27.  Looks like two flat pieces to cover gap.  I always had in mind something that was multidemntional in thickness.  In other words, the gate slide would be thicker on the part that actualy covers the gap, it would fill the gap and make the internal surface of the mast channel flush so the slide would transition across the gate area without haning up internally.  That probaly over complicates a design but that would be the best solution to provide a smooth internal track.

This is the C-27 item.
