OK, just kidding, I'll keep it short. My knock down drag out with Catalina is over. They took a reasonable amount of money and sent me a beaching rudder, as is, no warrantee, not returnable. (It arrived in perfect condition.) I will not bring in my third gen. for warrantee repair. For grins I took the following picture:




As you can see, the wet surface area is about the same, roughly 2.5 sq feet, untill the boat starts heeling and rocking and rolling. If the rudder comes out of the water 12 inches, the 3rd looses three quarters of its wet surface, versus the beaching rudder roughly 40%, I think that is where the key difference lies.

Here's the new rudder mounted. As per Arlyn's web site (balancing the beaching rudder) I attached the line to see where the leading edge of the rudder ended up.....it appeared to overlap the line by about a quarter inch, with the rivets in the detent, and the lock tightened down. I will sail with it the way it is and see how it handles, and if it holds up or whether it starts wearing and getting loose.



On a final note, the third gen. tiller hardware (of course) doesn't fit over the beaching rudder head. The new head is about 1/4 inch too wide. So I did order the straps that go with the beaching rudder, but not the tiller itself. I was able to mount the old tiller with it's U-channel between the new straps after drilling three holes in it. A wood block (out of sight) keeps it at the right height. So now with the installation/removal of three bolts the tiller (with extender) serves both rudders


If the weather, my employer, my mother in law, and Murphy cooperate I'm going to get some sailing in next week. If so, I will report on the handling.

Ok, side by side the beaching rudder looks about 10 inches longer? Hard to see.... Now I'm curious because I think my 3rd is longer than yours in the photo. Guess I'll have to go measure the length of my 3rd gen rudder in daylight tomorrow. By the way, what is the length of your 3rd top to bottom?

Hey Oscar, good job!
Years ago I raced a Catalina 22 with a kick-up rudder at FT Gibson in Ok. It was blowing really hard and the rudder kept coming up. It had one of those donut compression clamps like yours does. I finally got it tight enought to hold for a while and then there was a load sprong noise and it had blownout the threads on the clamp. We had to retire. I thought about that event after it happened and decided the rudder needed a couple stainless pins. I figured one at the top of the rudder head and one at the bottom of the rudder head. A nice bushing glassed in the rudder for the pins to go through and little lanyards on the pins would make it all good, Of course part of preparing to head towards shore would be the pulling of the pins but during the time on the water they would make the rudder behave like a non pivoting rudder. If this may be the last kick-up rudder you will ever be able to buy you may want to give some thought to re-engineering it a bit.

Suzie, My third is 59" or so.

Frank, with the CB up the beaching rudder sticks out well (a foot or so) below the deepest part of the boat...so steel pins woud be a bad idea. Wooden dowels as shear pins have been suggested. Arlyn put a bungee (he loves bungee) and a cheek block. Works really well he says. If the factory setup wears out, that's the way I'll go.
