The emergency tiller is short enough to use without removing the pedestal.  I don't have a camera to take a photo, but I will get the measurement in the morning and post it for you if no one else post it before then. It is a good idea for all of us to practice with the thing from time to time to test our skill in case it ever has to be used.  It is a lot different than using the wheel. I would hate to have to use it in heavy seas.

You should not have to remove the pedestal. The emergency tiller in your case would be nothing more than a short length of pipe that fits into the fitting at the top of your rudder shaft. This is based on the year of your C36. When Catalina started  manufacturing the walk through stern, it becomes a much different setup, but still does not require moving the pedestal. http://www.catalinadirect.com/index.cfm/product/1319_805/emergency-tille...

I had to use the emergency tiller when my steering cable snapped.   I had about 4 miles to get back to my marina.   About a 2' beam swell on the northern Chesapeake.   VERY difficult to steer, under power.   If the boat heeled and veered off from a swell, it took all of my strength to get back under control.  I finally took the bottom half of my dingy paddle and put it over the tiller, sticking out of the walk through transom.   This provided needed leverage, still a lot of work, but we made it back.   I was exhausted when we got back to the slip;  going into the slip in reverse was a real  adventure.

I'd like to second the request for a picture of the emergency tiller. I don't think my c36 mk1 came with one. Might help to know what I was looking for.

Here is a pic of my emergency tiller for a MK II. It came in a red bag marked "Emergency Tiller". I obviously have not had it out in a while and it has gotten a tad rusty. I didn't mount it but put it in the spot where it would be attached to give you some idea of the size. The pipe extends the rudder post up and the insert off to the side allows you to steer without removing the wheel or anything else.

Hope this helps. On my C 30 the tiller was a wooden tiller similar to what you'd have on a C 22 but shorter.

Good picture Chuck.  BTW - I think your nails look really nice...  ;)

Thanks.... I had just had them done for Father's Day.

I posted my steering failure today.   I am having a reinforced plate made for the transom bulk head that failed.   I had the short pipe emergancy tiller.   It was usless in reverse, I hit pile backing into slip.
I am also making a extension handle with a dog leg and be extended to clear Edson pedistil and still give more leverage.

Will let you know how it works out.   Have some pictures.    Drew up sketch for more substantial re-inforcement.

I know it us a good thing to practice with the emergency tiller. But how many have hyd autopilot's?. That would be my first resort if my wheel system failed. .

Another thing to  consider is, how many people have tried to actually open the emergency tiller access port? Sitting on the deck it can get tight with salt water and dirt and then in an emergency...... best to make sure its easily opened when your not up to your a__ in alligators.

We have a 1983 MK I model. Here are photos of the emergency tiller that came with our boat. 

Update Nov 2015:
I added 2 photos showing the top of the rudder under/in front of the aft locker where the tiller handle attaches.

Here are 2 images of the one on my C36. It is 32" long and comes in a carrying bag. To make the cover removal easy, I made a handle for it. To keep the cover from seizing I use pipe thread paste on its threads.
I have applied Lanacote to the axel of the steering wheel and the threads on the holding knob and I make sure that it is free for removal. I keep a steering wheel removal tool on board in case the wheel will not come out.
