Rudder Blade; I lost it.

Hi to all!

I have a 1985 Catalina 36.

On a heavy sea, I have lost it, it fell down to the sea, yesterday.

The depth of sea was 300mt apprx.

Now, I need a new one.

How can l get the drawings and dimensions and material type etc.?

Can l produce a shorter one in order to prevent damages in shallow water decking?

Thanks a lot.

Sorry to hear that!

I suggest you contact Catalina Yachts directly, they should be able to tell you what the requirements are. Another member may have a name and phone number there, but they are very accessible. Good luck!

Also, PLEASE share the story of how you lost your rudder in "heavy seas," especially what you did afterwards!

We would love to hear. We'd love to know you more, too: why not put some information about yourself and your boat in a "signature" (through your 'My account' settings)?

Hi,

Believe me, l've read the answers "just now."

I was upset and a little bit "angry" to the forum, because nobody helped me!.. :)

I dont know the reason but, inspite of l checked the forum daily, sometimes hourly, l didnt see these answers..

Thats why l stopped writing to the forum.
It is my fault and l apologize to people whom wrote to me.

So..

I've solved my problem with my rudder blade. I myself built a new one. A shorter one!

I will share the story and pics about rudder blade, and sure other experiments...

l have a plenty of nice pictures, memories at Egean and Mediterrain Coasts of Turkey and Greece.

Hi to All!

I can connect to the forum now easily.

I attached some pics for the rudder accident / trouble.

The reason, that the rudder shaft is broken is electrical (galvanic currents)

The grounding of the 220V shore power was connected to the minus (-) terminal of the boat.

I seperated it and connected to just to the 220V charger.

After I constructed the rudder, -because I changed the geometrical shape- I had to disassemble the rudder. In there days the new rudder shaft was in a real damage.

After I changed the grounding of 220V, after a season, just 3-4 weeks ago, I disassembled the rudder, to check and see what is going on, I saw that everthing is ok.

I've put 2 spelters on the rudder blade + I've connected the rudder shaft to the other spelters on the boat.

Interesting story. Thanks for sharing it. I'm no expert in electrical grounding on boats so this might not be a valid comment, but on all the sailboats I've owned, none of them had electrical grounding to the rudder shaft or any part of the steering system. Probably a good idea to remove it. Is there a chance that is was crevice corrosion? It looks like some type of filler (epoxy?) is inside the hollow rudder post- maybe salt water migrated inbetween the filler and stainless steel and was starved of oxygen creating the corrosion?

Hi,

I do not have grounding at the rudder shaft -nor anywhere at the boat, except 220V battery charger-

The shaft is connected to the spelters.
Maybe you are right, I am also not expert, but because I am afraid of electrical issues, I connected every metal part of the boat to the spelters. (I have 5 spelters under the boat.)

The absense of oxygen for stainless steels under the sea... It is also a topic. :)

Unrelated, tell me about your swim platform? Does that flip up?

Hi,

No, it can not flip.

I made them at cnc router at city Istanbul.

I've attached 3 pics.

Ozkan,
The pictures of your swim platform are very interesting. It appears you have a swim ladder that is also a gangplank? I think a few of our members would be interested in how you came up with this design and how you fabricated. I would believe how you accomplished the pass trough the stern would interest members as well.
I just noticed by your other pictures that the pass through is rater new and that you helm is offset to the port side. Very creative!

Yes,
 
It is a swim ladder. It is also a gangplank. :)
 
I have lots of renewals - support at the stern, before I cut it.  Many struts, many brackets.
The floor where the original helm pedestal  was about 12mm crumpled/caved in. I've also supported this floor with epoxy + poliester + fiberglass.
 
Unfortunately, we are a mostly a cruiser/holiday focused family, than a real sailor.
So the comfort is in front of sailing FOR US.

The original helm was about 80cm, Now 59cm.
And at the very port side of the boat.

And the center of boat is for my usage area.

The boat is like a building yard now, I will share what is requisted from me, but at a different / related topic.

Ozkan (Andac):
Very interesting modifications to Molto Cattiva ! 
What is the material you used to cover the cockpit seats? Is it a teak substitute of some kind?  Definitely makes it look nicer  (and not, um, çok kötü )

 We have a similar platform on our boat, but it can be flipped up by removing 2 pins or bolts from the braces underneath (although we've only needed to do so once).  See photos at
