We were on Biscayne bay this weekend for the Columbus Day Regatta (ok, we were on the bay so was the regatta!) and I noticed that our port side lower shroud had sprung a wire at the point where the wire entered the lower shroud fitting.

The single wire of the entire shroud had correded out and was stuck outside of he fitting ready to catch the unwary.

So I figured I had better order a new shroud.

Of course, if one has gone bad, then it could the be the others are ready to follow. The boat's only 3 years (3yrs 4months) old and we are in south florida. So should I replace all the shrouds?

I'll have to remove the furler profile in order to inspect the forestay.

Wow, that seems like a very fast deterioration. Having said that I would be inclined to replace them all. I'd be especially concerned about the forestay. If it goes the mast is coming down. Maybe you should contact Catalina or your local dealer. Three years seems incredibly low, especially since you don't keep your boat on the water.

Thanks Randy.

Update:
Spoke with Catalina and they were suprised that a shroud had failed (note, there was no damage to the boat, it was found during inspection.)

They suggested I inspect the other shrouds and that it was probably a case of the shroud that had a broken wire at the swag was probably due to excessive stress. This could well be as I had to replace the T-bolt at that location as I accidently stepped on the turnbuckle and bent the T-bolt.

Today I removed the lower shrouds and inspected them. I'm going to replace them both, nothing special about the 2nd shroud I just feel it a good idea.

Inspected the back stay that's fine.
Inspected the outer/upper shrouds and they are fine too.

I had to take the furler apart in order to inpect the wire inside the furler profile. Amazingly easy! I marked the turnbuckle with a thick red marker before removing the split pins so that I had a clear mark when putting them back together. The forestay is fine, in fact the furler seems to reduce the exposure to weather significantly.

So the long and short of it is that I'm going to get new lower shrouds from Catalina Direct, they were very helpful. I'll place the order on Monday.

Still have not found a supplier for the Gibb T-Bail Rubber retainers except for a company in the UK. So if any of you know of a US supplier please post here.

As for the broken wire at the swage, when you trailer your boat, do you secure the shrouds so that the turnbuckles aren't "waving around" on the road? If the turnbuckles are bouncing around, the flexing right at the swage could be the culprit. Of course it could just be a faulty swage--not properly compressed around the wire. Three years is too short for ordinary corrosion.

Good points Dave,
when we prep the boat for trailering, I use ti-wraps to secure the shrouds in a vertical position (the wraps stay in place until we next raise the mast at which point they stretch and break off, they are the very thin ti-wraps.) So the turnbuckles are certainly restrained.

Hi Paul,
I lost my link for the rubber plugs, but I found this [url="http://images.google.com/imgres?imgurl=http://www.mauriprosailing.com/Navtec/Navtec-images/web-08/Nav-Rubber-Plug.jpg&imgrefurl=http://www.mauriprosailing.com/Navtec/navtec.htm&h=80&w=80&sz=2&hl=en&start=1&um=1&usg=__G5qt_2PG6D1oVufBOyw0IDYPHbM=&tbnid=lOHZ988X7kdtRM:&tbnh=74&tbnw=74&prev=/images%3Fq%3Dgibb%2Brubber%2Bplugs%26um%3D1%26hl%3Den%26rls%3DGWYA,GWYA:2005-04,GWYA:en%26sa%3DN"]one.[/url] Maybe one of these will fit.

Paul,
Don't order them from RigRite, they charge outrageous shipping. Get them instead from Fisheries Supply here in Seattle. Here's the one I think you need: [url="http://www.fisheriessupply.com/online/ln_menu/product.asp/mode/1/product_id/94900/displayKey/Navtec/Ntt/t-ball/N/-76110/Nty/1le/R/27493/act/A01/catalog_name/FISCO/partnumber/NAV+N742-06/Ntx/mode+matchpartial+rel+Inactive"]GIB 742-6[/url]

Here's the response I gave someone else a while back:

If I remember correctly, it was this:

Retaining Plug for T-Ball w/ 3/16" & 5mm wire: GIB 742-6:
Rubber Retaining Plug for use with Gibb T-Ball Backing Plate Tang, GIB 740-6, for 3/16" wire. Rubber Plug (visible when installed) is 5/8" (16mm) high x 11/16" (18mm) wide.

But I'd measure an existing one to make sure. These can also be had from Fisheries Supply, and they're cheaper by a bit. As I remember Rigrite had a $12 minimum shipping fee, even for tiny things like these, so if you only need one or two, you might check out Fisheries first.

Edit: Just read through this & realized it was a bit hard to follow. I ordered mine through RigRite & paid just as much for shipping as I did for the plugs. About two weeks later I found them while looking for something else at Fisheries. I think they're about $2/each from them. I'd still measure your plates to make sure you're getting the right size, my mast it almost a decade older than yours, so they might have used different sizes.

Tom, thanks again. Just chatted with Mauri Pro and they tell me the correct item is N742.06
but they are out of stock (luckily I called, so they can reorder :)

I also spoke with them about the shrouds, they are sending a measurement diagram.

Very helpful folks.

Finally placed my order for new lower shrouds from Mauri Pro this evening.
Like all of the other companies that I spoke with, they told me to measure the shroud rather than use the figures from the manual.

Here's the pic they sent me to assist....

I took the shroud off the boat including the turnbuckle. When I measured it (3 times) I got 167.5 inches as per the pic.

But if you look in the manual, it's 15' 1/2" but that is 180.5" !!!! (The manual is for the 8-9-1995 models!)

So it was very worthwhile taking the trouble to measure them.

If I can get the mast up this weekend, I'll measure for my twin backstays to add to the order.

FWIW, I've never included the turnbuckle in the measurement. I guess it depends on the company.

I can't imagine not measuring pin-to-pin. But I'd measure with the turnbuckle set to where you've had it on the boat (not necessarily at the mid-point). The new shroud will be sized to give you that length with the turnbuckle set at the mid-point--right where you want it.
