Mast Collar/Boot Kenyon 5280 for H37c

[Rovic]

I have unstepped my mast and in the process destroyed the black rubber mast collar. So now I'm trying to find out what it was. H37c seem to have the Kenyon 5280 mast profile ????.
Looking on the Rigrite site I came across this.

"Urethane Mast Collar for 5280 Low-Profile Deck Collar: K-10768:
Black Urethane Mast Collar with flange for 5280 Deck Collar Assembly. Unit mounts between deck and upper Deck Collar Ring. One piece molded construction requires that unit be slipped onto Mast (with Upper Deck Collar Ring) before stepping. Formerly supplied with Low-profile 5280 Deck Collar Assembly K-10946. This item is no longer available, having been replaced by the K-77509-24 Rubber Mast Wedge, shown above. **When replacing this item with the K-77509 Rubber Mast Wedge, the Aluminum Deck Collar Rings are permanently bolted to the Deck (inside and out), and the Rubber Mast Wedge is installed after the Mast is stepped, greatly simplifying Mast stepping."

Does anyone know if this is the right replacement part and is the K-77509-24 Rubber Mast Wedge, a series of wedges or a continuos band with a split.???
Any recommendation for a mast boot for the H37c.????

Thanks

Did a search and found several references to the 5280 as the right mast section for the H37C. I always thought the collar was rubber. I am still using the original along with lots of silicone.

As for a real mast collar I think you have to modify the partner to get what you want. You would need to weld a 3/4" to 1" high ridge around the inside perimeter of the partner. That would give you something to fill and then clamp a cover over.

I liked the rubber collar that was there prior to my destroying it, as I had never had any leaking down the outside of the mast. Mind you I had buckets full coming down the inside of the mast but that's another story. My main curiosity concerned if the K-77509-24 Rubber Mast Wedge was in fact a wedge ( singular ) of which a number of them would need to be used, or a one piece rubber collar with a split. In my early days of sailing my mast was supported with wooden wedges to help centre it once it was tuned up.

Mast Wedge for 5280 Deck Collar: K-77509-24:
Extruded rubber Mast Wedge with flange provides even loading all around the mast. One-piece construction is far superior to individual wedges, which cause point loading leading to deformation. Cut to length for use with 5280 Deck Collars.

Seems to me like this is a continuous wedge-profile collar (with split). I'm about to go through the same to please let us know what you find out

 

[Ed Schenck]

Think Coleman is right, a continuous wedge, probably rubber, with a split. Looking at an end I would expect to see a trapezoid. The top and bottom are parallel but the bottom is slightly narrower than the top. Might go in a little easier.

I could only get mine in by slathering with silicone and then using the shrouds to pull the mast to one side and then the other.

Anyone here used casting compounds to form a collar in place?

Here's a good write-up. I was debating this as another way to do it and was really happy to find a write-up.

 

[Ed Schenck]

That is an amazing amount of work and money to fix a problem that I never had. And I don't think he had either. That works for him because he is able to put a boot around it. You can't do that unless you weld a lip on the inner perimeter as I wrote about earlier. Or maybe you can purchase a mast partner for the 5280 mast that already has one.

How about, when rebuilding the mast step area due to water intrusion and core damage, one were to build a flange, or dam, all the way around the mast step, then wrap the whole thing with stick-to-self amalgam tape?

i used SPARTITE on mine last year, you just mix it, and pour it in, no leaks, no hassel. i did the same thing with the old rubber ( destroyed it ).. i am really pleased with the SPARTITE.

Just took mine out and used spartite to reseal it. Mast doesn't leak for the first time since new. It is a two part polyurethane that is the same material as inline skate wheels. Just dig everything out the top, clean it, wax it or use another releasing agent, and pour it in. It sets up in fifteen minutes. Make sure you seal the bottom. Modeling clay worked well.

Thanks Peggy

I just got my mast back in. Was dreading driving that split rubber ring in as mast was up against front edge of partners. Cranked down on back stay, lubed the ring with KY jelly, and drove it home. Whole thing was 30-45 minutes. Yahoo

 

[Ed Schenck]

That thing is a bear alright. I usually have to have loose shrouds and loose stays. Then I have someone pull the mast side to side and fore to aft while working it down. I use a heavy rubber mallet to beat it in. But loaded up with clear silicone I have never had a leak. So you are done and ready to go sailing?

Couldn't figure out what I had to do with this...

Then I saw you'd found another use for K-Y. :dance:

It's the best lubricant I've found for any tight connection...but it's water soluble so it's not what you'd use for pumps, seacocks etc. ..just for getting hoses onto fittings and--apparently--also masts back into boots.

You do still need to use a sealant on the mast, though.

For the past 2 years, we've been using a clear pvc hose instead of the original collar. We wedge the hose in, then apply a large amount of silicone on top. Doesn't leak, and cost just sort of 1$. It also is a lot easier to remove if you step and unstep the mast frequently.

 

[Bill1565]

Almost ready. Got to put boom on, sails, and rig staysail. more stuff below decks before we leave for the everglades and keys

 

[Bill1565]

I used to live under a rock. Only knew of one use.

Three of us went to pull our masts together. One had a piece of 3 strand nylon stuffed in the gap. Our rubber seal popped right out of the deck when the crane lifted the mast, so it was free to re use. Hope never to pull this mast again

 

[Ed Schenck]

I don't think that I ever read the final story of the mast wiring. Were you able to get the luff track out and the new wire in?

 

[Bill1565]

No. I wound up inserting 6 pieces of 3/4" conduit, enlarging one of the holes at the masthead and pulling it out the top. Cut off the base inside the mast a foot or so. Put a SS bolt thru the conduit at the mast head , riveted it to the bottom of the mast and ran MH light, wind instrument and VHF coax thru it. Bought a multi LED anchor light from Bembii electric in Fiji. It was a 1'" PVC PIPE CAP with Led's and a photo cell . Fit a piece of 1" PVC pipe over the 3/4 " conduit, put the anchor lite on it and quit.

Best part was reading the Fijian newspaper uesd for padding.

Took yesterday off. Took two naps, hung upside down in my inversion table, sat in the hot tub and drank beer. Fished in my canal. I already told you about today's sucess I think. Having a cook out for the mast crew tomorrow, will cut into my work time, but I really appreciated the guys helping out with mast removal, raising.
