Post subject:  Tandem Adventure Island Rudder problem
Hi,

I'm having an issue with my 2014 AI. I took off for a sail yesterday and noticed that the rudder was acting strange and had a lot of resistance when moving the steering handle. I turned around and went back to shore. At that point I could not retract the rudder with the cable or pushing on the rudder. It would get stuck about half way up.

Something internally is hung up. Is there an easy / quick fix to this type of problem. I would appreciate any tips.

Thanks for the help,
Dave

Lines may be hung up on a floatation block inside the hull. Use a cell camera and video around inside the hull to see what might be happening.

Thanks for the advice. I found the rudder "down" line in the rear seat twisted.

One other issue is the steering handle makes creeky noises when moving it from the left and right. Should I spray the metal internals with lubricant?

I appreciate the help,
DF

Yes, lube and maybe underneath. The crank has a spring that may be grinding.

Will do Matt.

Have you had any problems reported with CorrosionX? I have some on hand and also plan to use it on my pedal system. I must have used some kind of lubricant in the past that really did a number on one or two of the rubber fins. The fin is completely cracked and fell off the pedal system. Strange...

Thanks,
DF

Yeah... some oils attack plastics. The MD180 has a wider variety of plastics with glass-filled nylon, Delrin and not sure what else. Best to stay with something like the Hobie Lube which is mineral oil-based... but has penetrating properties.

I had a similar problem, which almost caused a disaster when my Ti's rudder became almost impossible to operate.

I solved the problem completely. I removed the front rudder up pulley (in the gunwale near the foot indents), and remounted the pulley forward alongside the big hatch in front of the mast (for easy access). I then added an additional length of Hobie dyneema (rudder) line, plus a FISHING TACKLE SWIVEL (heavy duty sort, with >20kg breaking strain)in the line heading back aft.

Now, the up-line between front and rear seats no longer twists, and the whole operation is smooth as a baby's!

I bought a second swivel to do the same to the down line, but have never needed it.

Very impressive Tony. I hope I don't have to go that deep! Aloha, Dave

Actually, it was quite easy to achieve. Once I undid the holding screws at the gunwhale, the return pulley dropped down into view. It was a simple task to add a suitable length of dyneema and swivel, and then remount the return pulley up next to the forward hatch. No mucking around in the bowels of the hull down back, and the twist undid itself because of the swivel. Now I hear a very satisfying clunk when the rudder hits its up or down limits.

The swivel idea is smart. Maybe hobie could incorporate that into the design because it would help non technical guys like me. I purchased my first AI in 2009 and this is the first time I've had any kind of issue.
Aloha,
Dave

I had this problem too. After taking it apart the first time to remove the twist, it worked for a few more days before getting really hard to pull again. When studying the problem I noticed that the handle line gets a twist in it due to how it's pulled. So I tried pulling the line out, putting an opposite twist on the line, then pulled it in and this had the effect of canceling the twist inside. Everything works great now. I've had to do this a couple times now but it's much easier than pulling out tools or buying new parts.

I did that at first, but decided that five bucks and thirty minutes would fix the problem for ever. For the life of me, I don't understand why Hobie puts the front "rudder-up" line block up in such an inaccessible place on the gunwhale, when the access next to the front hatch is perfect. Seems crazy just to save a few feet of dyneema line, but make servicing a nightmare.

John, regarding the opposite twist of the line.
- Do you go clockwise or counter clockwise?
- Do you give it a 360 degree or 180 twist?

Tony, your 30 minute fix would take me hours. I'll go with the twist.

Thanks,
Dave
