AD16 rudder: Ronstan spring & clevis pin

Post by Bogieman »

Jacques mentions (AD16 plans) a Ronstan spring/ clevis pin assembly to keep the rudder in the down position but there's no illustration. Any of you familiar with the set up and how it works?

It's a clevis pin that you push through the hole, say, for example, the hole through the pintles, and then you can fold the tab at the end opposite the ring, to secure it. To release, you fold the tab back inline with the pin, and pull it out with the ring. This is much handier (although perhaps just slightly less secure) than having to fiddle with a cotter ring, often called a ring-ding, like this:

Hi Bogey,
I was also puzzled what was meant with this ronstan pin, but when I bought my 3 piece rudder fittings I found out that there was also a small strip of stainless steel with it which needs to e srewed to the transom and prevents the rudder to move up. When one wants to remove the rudder I must just press the strip with a finger towards the transom and I can lift the rudder up. Here is a picture of the fittings and it is in the high position.

If You also get similar 3 piece pintles ( I think is the correct word for a rudder fitting ) then you have the advantage to attach the rudder one pintle higher in shallow water.
Maybe this helps you a bit.

Thank you Tony and Karl! That answers my question. I also plan to attach a small tether to the rudder so I won't lose it if it ever becomes detached.

Pintle is the one with the pin; gudgeon is the one with the hole. In some boats the pintle is on the rudder, sometimes it's on the transom.
Commonly, they are offset slightly so that when you're in the water and things are moving around, you can get one in and then maneuver the second.
