Posted: Tue Sep 07, 2010 1:31 am Post subject: Rub Rail Repair..... |
|
|
I had my boat alongside my dock last week...I had mooring whips, but somehow we had a ton of wave action and the boat came to close to the dock edge....and ripped the rub rail loose for about 5 feet....it sheared off the pop rivets....
I am sure this has happened to others... So what should I do ?
Drill out the remainder of the rivets and use screws ? or bolts ?
Anything else I should do while I have the rub rail off ?
Thanks
Gotta do it this week.... Lake Powell is coming us really soon...

On my 16 footer I didn't have access to the inside gunnel. I injected some two part epoxy where the rivets had been, waited a day for it to harden, and used stainless screws to secure the rubrail. Two years and still holding. _________________ MartyP

The same thing happened to my boat last year. I pulled the rubber strip out from the transom and half way up each side.
I drilled holes all the way through the aluminum and fiberglass and used SS 1/4" bolts with washers and castellated nuts. Then replaced the rubber. I wished that I had gone all the way to the front as it has started to come loose also. A next season project.
Make sure that you use good quality SS bolts/washers/nuts if around saltwater. _________________ On the HIGH TIDE-II, wife Carolyn and I.....Another summer fishing on the HIGH TIDE II in the Cook Inlet at Cape Ninilchik, Alaska.

Joel,
Sorry to hear about your rubrail. If you can get access from the inside then you can just drill out the existing holes and re-rivet, however if no access, just fill in the existing holes with 5200 sealant and re drill new holes an inch or so away from the old holes. You will need to make new holes in your rubrail but that will not be a problem, and you can either secure with screws or rivets.
I hope that this information is helpful and don't hesitate to contact me direct with any further questions or comments.

Not difficult to do. Just time consuming. Requires a second person in the boat while the other is outside.
Remove the rivets, replace with SS Screw, ss fender washer, lock washer or castle nut. I used a dab of 5200 on each one to ensure no leaks.

Joel,
Our 1995 22' had the rail pretty loose when we bought it and I added a few bumps myself. I posted pictures of the rub rail repair in our album. Really a pretty easy project and I would suggest that you replace all the rivets with SS bolts and washers while you are working on it. An easy weekend project.

My experience has been when SS bolts or screws are used through aluminum (rubrail base) which is often in contact with saltwater you will get some corrosion of the aluminum unless you can insulate the SS from the aluminum. Generous use of 5200 around the bolt may help? I have never had a problem with my rubrail but I have seen significant corrosion of aluminum parts bolted together with SS bolts. _________________ Ken Trease

It might be a good selling point for the factory to attach the rub rail with stainless steel bolts and fasteners....I think everyone has had or will have problems with those darn rivets....... in doing the boat I found at least a dozen that were not holding in places that should have been fine.
I replaced ALL the rivets with tapered, philips head 10-32 screws and countersunk the rail so they would be flush.... then used SS fender washers and nylock SS nuts....
BUT almost all the way through I ran out of fender washers....now we live in remote Northern California....and I had bought my stainless steel stuff in Red Bluff (in the valley)....I paid $9.95 for 100 washers (.0995 each)..I was only 13 short...so I went downtown to the local hardware store....
I expected to pay maybe .16 up to .25 each for them (outrageous markup) but guess what they wanted........ $ 1.18 EACH !
I laughed and told the man that was ridiculous and he said....drive to Red Bluff if you want...with a smirk on his face... SO in proper Roger King fashion I said....... Ed..(the owners name)...before I buy your overpriced washers I will drill out half dollars and use them as washers.... So every time I look at them I will remember what a crook you are....
And that is just what I did...

BTW, I have about 8' of alum rub rail for a TC255 if anyone needs some.

I see from the postings that this is an old problem and my 1995 C-Dory 22 is now shedding its SS pop rivets under the rub rail faster than dog's hair. The heads of the rivets appear to epoxied over with a big glob of Bondo or something. So I assume the fix is to drill out all the pop rivets and replace with SS bolts and lock washer/nut combinations. 10-32's seem to be suggested, but how long? I am guessing that 1 inch will do? _________________ /Dan/ |

I just finished doing about 7 rivets on each side, amidships (water gathered at the low point in the rail and corroded the rivets - not the best design), and three at the transom. I had read some prior posts (very helpful, especially ones by "Comfy Dory"), but then made a few more discoveries as I went. I took photos and was thinking I should write it up. I'm just eating dinner but how about if I get around to it later this evening?
I'll probably post it in the thread I made for my boat projects, but I will come back to this thread and leave a link to that one. |

When I purchased OSPREY, the rub rail was loose amidships on both sides. I let it be for a few months and then decided to bite the bullet and take care of this problem once and for all...
Like others have stated, water sits on the rivets behind the rubber of the rail and eventually eats the aluminum rivets away due to corrosion. Reinstalling rivets in place of those that failed would only be a short term solution, so I decided to remove the rails completely. You do need some help to prevent from allowing the rails to get distorted while removing them. This process also allowed me an opportunity to clean up the dirt behind the rails and also bed the entire rail, so that dirt will not get between the rail and the hull.
Drilling out the old rivets and punching the rivet core through the hull with a small punch was very easy (again I had a helper hold the rail as I worked). I used 316 stainless fasteners that were 10-24 and used nylock nuts for locations that were not visible and used crown nuts for locations that were visible. I bedded the rail and fasteners with Sikaflex. Also, before bedding, I applied blue paint tape to the location above and below the rail, to make clean-up easy.
Lastly I put the rubber in a bucket of warm water and then used soapy water to aid in installation of the rubber.
Bottom line...to start the project looked huge, but it was relatively easy and the end result looks very good. _________________ Steve Baum
