Roller Furling Pin Snaps Under Load...

We have spent the past couple of days trying to get some time in the 26s in some heavier winds...which we succeeded in finding! Today we were met with a potential disastrous and deadly situation. We were under a reefed main and full genoa. We were still in the River so there were no waves and winds around 15, gusting to 20-22. As we changed to a starboard tack we were met with a gust, she heeled over and started accelerating. Suddenly there was a loud snap that shook everything. I released the main and was asking Kathy what snapped. Suddenly she said the roller furling in not attached. My eyes bulged as I looked forward to find that a small 3/16" line was the only thing holding the rigging up...the genoa was still powered up. I gave the order to start the motor and turn us downwind. The furler would not work. I ran forward and physically turned the furler and wound the genoa up and tied it off. I used the jib halyard as a forestay and pulled it as hard as I could and cleated it off. In the meantime, Kathy had dropped the main. This whole event took about a minute or two...but seemed really fast. Afterwards...I just sort of collapsed against Kathy as we motored slowly back to The Steel Magnolia.

The pin in question... This was a 1/4" pin with the spring ball retainer on the end. The original owner had a couple of loose ones and a new one in the bag; all of this was in a ziplock bag marked "pins for Jib and Stays." Once back at the dock I pulled out the bag and to my shock...the one that was still bagged up was something you would buy at the hardware store! I almost croaked! We headed over to west marine and purchased a 3,000 lb working load pin. We came home and was finally able to get it in. I will be looking at ALL the pins and hardware to make sure there is not some more hardware store junk holding things together.

The little string... Since we were having problems getting the forestay attached when stepping the mast, I used a piece of the 3/16" line I had recently purchased to thread through the base fitting on the furling and make a loop about 2' long. While on the trailer, I could use a ratchet strap from the trailer to this loop and use it to pull downward on the line to help position the furler so I could pin it. The small line basically comes down each side of the bow of the boat. I have been just wrapping it around the chainplate fitting just to keep it out of the way. Fortunately, when things snapped the line bound itself to the fitting and held everything in place...only allowing about 4 inches of slack. This tiny line was rated at 1,200 lbs breaking strength.

We are so blessed that everything happened just as it did...and very thankful for that tiny little line that potentially saved our lives.

Just wanted to share this in hopes that another newbie doesn't just assume that the previous owner didn't cut corners on parts that carry a critical load.

Glad everything worked out okay! FWIW, those plunger quick-pins have a bad reputation on these boards.

Was the pin that failed lost? It'd be interesting to try to infer its cause of failure from a photo.

It was not the plunger type (with the push-button on the end). It was solid with the little pressed in spring ball near the end. Yes, all parts of the pin no where to be found...as loud as the snap was...it is possible a piece of the pin may be in your yard! LOL

Wow... glad you had the extra line in place!! You may want to post pictures how the furler is connected at the bottom AND the top, let the folks here comment on it. You should have proper "toggle's" at both ends and also there is also a turnbuckle inside the furler drum that should be checked - if this screws apart the fuler fails..

yep... pins with the little detent ball at the end are not "boat quality" hardware. it probably worked its way out far enough to be shot out, and the noise was when it richocheted off of something. its not likely that it broke, but would have bent, as they arent hardened pins.
the ball lok/kwik lok/pos lock (different brands) are a much safer option.

but you mention it as a 1/4" pin... on the Mac 25/26, it should be a 5/16" pin rather than 1/4".... much stronger. it makes me wonder if the furler may be off a smaller boat and was retrofitted without beefing up the hardware:oops:

Not sure about the 25's but our 26S had 1/4 inch pins and stock a 5/16 would not fit at the bottom of the forestay. I switched to 5/16 when I upped the forestay from 1/8th to 5/32 but I had to drill out the hole where the bottom toggle for the furler attaches to the boat for it to fit. The Johnson Levers most owners use, if they use one, also have 1/4 inch pins but I went with the next larger Johnson Lever...

....which used the 5/16 and then upped all the 1/4 inch pins to 5/16,

Thanks for the feedback. I will take pictures later today as the weather allows. The fitting on the bottom of the furler is 1/4". I can't speak as to origin of my CDI furler or what it may have been on previously. If I remember correctly, the bolt that holds the forward stay/furler on the mast is 1/4". I have checked the pin (the one that failed) at the beginning of every trip (the boat is currently in the water at our dock) and it had not moved from its original inserted position. There was no bending, etc noted. Again, the replacement part I used was from West Marine and has a double ball on the end with a pull ring on the other and is rated at 3,000 lbs working load.

The load rating is fine but I just wouldn't trust that style pin myself for this application. I thing there is a reason that...

... a pin with a ring ding is the standard for this job.

The ring dings come in various styles and can be a pain at first to deal with but after using them some it becomes easier/faster. I like the ones above but others prefer a different style. Use what you like best.
I do use pins with the balls for other applications on the boat that aren't critical. As Walt mentioned by the time we get these boats it is hard to tell what was stock or not as we, along with the previous owners, make mods to the boats.

My 25 had the original rigging, and is not fitted with a furler, but it is a 5/16 pin, and the only 26 that im that familier with has a 5/16 pin, so i assumed they all did, but apparently that is not so...

If the hole isn't 5/16 it sure ....

...doesn't take much to get it there if one wants to move up to a 5/16 pin for whatever reason :),

While you are working on the furling and checking the turnbuckle inside the drum (it needs to be pinned or it'll unscrew) be sure to check the upper forestay terminal. On a CDI the wire/terminal connection is usually inside the foil.
Here is the surprise I found when I checked it the first time!!

Chris,
Thanks for sharing and the carter key reminder! That has got to give you some comfort...knowing that you found that before things went bad! I have ordered and received a new forestay (I as adding a Johnson Lever similar to what Sumner did). I upsized to the 5/32" cable. I was really amazed that the tiny increase from the 1/8' to 5/32" cable increased the capacity from 1,700 to 2,800 lbs. I finished measuring for the new genoa today. ...Time to get that ordered!
