My I37 rudder post seems too loose in the tube, it moves about an eighth of an inch side to side.

Has anyone added bearings to the tube, or is this something I shouldn't worry about?

Mine too

I have recently purchased an Islander 28 with a siliar problem. I have not addressed this issue yet. When I learn something I will share it with you for sure.
Hit me back, Scott

when we had our 37MS out this past spring I did notice a phonolic ring at the top of the rudder at the hull. Ours was hanging out and cracked. I did not think anything about it and later learned the hard way. My rudder started to catch going thru center under load. I realized this ring was not a spacer but a brearing of sorts. Our last sail fo the seasom in 20kts close reach our shaft failed. I bleive this is unrelated to the lower bearing and more about corrosion. I am building a rudder and will replace this bearing or sleeve to take out the play. Is the play at the top of the tube above the tube boot, or is the play at the rudder/hull area? I am also trying to find info on how this system is made up. It is hard to plan without blueprints or diagrams. If you find any sources of information will you please post.

Rudder stock & tube bearing repair

All of these boats with need this repair eventually and there are several solutions ranging in effectiveness and cost. Free and "better than nothing" would be install sleeves made from plastic jugs. I think you would need to drop the rudder to wrap the sleeves around the stock...

The other end of the spectrum would be to replace the tube with a modern system which has two bearings, one at the top and one at the bottom. The best systems have "spherical" bearings which can follow along when the rudder is loaded and its shaft bends. Big project, more money...

I can wish for one of those great modern rudder tube bearing systems for our i28 but am more likely to invest in a new Genoa... My repair will follow the strategy shown in one of the West System project guides.

They show how their epoxy system with a Graphite additive can be injected into the existing tube where it flows around the stock to create a new bearing surface. I think their guide was "002-550 Fiberglass Boat Repair & Maintenance".

Although you might perform this job with the boat in slings, you have to prep the rudder first. The best & longest lasting repair would come from having time to polish the shaft first. Some yards around here will accommodate a boat in the slings overnight. The correct epoxy would be cured in six to eight hours and you could be back in the water the next morning.

Also, I believe one of the "Offshore" magazines (Cruiser or Navigator) recently had an article showing a worn rudder stock getting "sleeved" with a new bearing surface.

Good luck!

Rudder post repair - follow up - ref

I found that magazine story on rudder repair. It was in "Ocean Navigator" September 2008 issue.

Good Luck with your repairs.

Tube play

Hi,

I did the West System job on our old Tartan 33. It worked great and not only eliminated the slop but also made the stock turn in the tube easier due to the graphite coating. The big hassle in the job is removing the rudder, perfectly cleaning and polishing the stock and then making sure the insides of the tubes are very clean for the epoxy to stick. You use a very small amount of epoxy mixted with graphite to create dime sized bearing surfaces for the stock. Really a nice fix!

Good luck!

Rudder post

[Ours seems to have play both at top and bottom. The supporting glass at the top seems very thin, I am worried about strength, I am thinking about making up a flange and attaching it to the cockpit sole somehow to take the play out of the top part.

I am staggered your post broke, it is such a strong unit.

Let me know if you come up with a solution.. May comes fast when you have these things hanging over your head.
