Question Morgan 34 Centerboard Diagram

We just recently got a 1967 Morgan 34 and, for the life of me, I cannot figure out the mechanics of the centerboard pennant and tube within the keel. We are hauled out and the pennant line is broken. I am really scratching my head on this one, and don't want to tackle a 250 pound bronze centerboard until I know what I am doing. I cannot find much of anything on the internet, so any help on this boat would be greatly appreciated.

This is an amazing boat. I have been accused of having the engine on, when sailing close hauled. The centre board is not complicated. It is actually very simple and easy to maintain.

The pendant leads through a stainless half inch diameter tube, within which it is epoxied. The tube leads through a stuffing box, which keeps the ocean out. The stainless pendant then connects to the centre board with a shackle. The board, if it was all the way down, hinges on a pin on the forward upper corner of the board. Here is where it connects to the centre board trunk. The aft of the board (remember, it is down for this explanation) is where the shackle connects. The board takes about 67 turns on the winch in the cockpit, to take it from all the way up to all the way down.

Morgan 34 Center board diagram

Here is a Morgan 34 Centerboard diagram. It will help give an idea of how the wire sits in the pendant tube. The tube itself houses the wire, and a packing gland is on the inside of the boat.
The 90 degree arc of the top of the board is what allows the pendant wire to always travel in a straight line.
In the event of a failure with this system there are probably only four that are likely.
-The wire could break at the tube (crevice corrosion), or it could break at the pendant swage. A break at the swage could be the result of crevice corrosion and fatigue: the swage is straight, and the arc it lays on is curved.
-The pivot pin could let go; how I don't know, but anything is possible.
-The pendant attachment pin could let go; again, I don't know how, since I haven't had a close enough look to know how it is secured.

A good measure to take, although it isn't illustrated, it to drill a half inch hole at the bottom leading edge of the board: in the event of a pendant failure a shackle can be attached there, and a line can be used to haul up the board. A loose board will likely be lost or damaged in any kind of a rough seaway if it bottoms out.

Re: Morgan 34 Centerboard Diagram

Just a reminder to those of us that have Morgans with center boards, don't forget to check the shaft packing where the piston comes into your bost. It too needs a look and wrenched same procedure as the shaft that propels the boat. Also, a drop of HD oil or light duty grease will go a long way on both the pulley and winch,. and wipe the piston with a dab of grease to smoove out its movement. I know that most already know this, its just a reminder

Re: Morgan 34 Centerboard Diagram

Well, three years later and the post goes on. First the idea of drilling a hole for future possibilities deserves a 'Nobel Prize'.

Now for my question. Anyway, I dove the boat to investigate the lack of center board retrieval and found the broken pendant. However, the top of the board is not the continuous radius that is described in the previous posts. The top of the board is actually 'U' shaped. When the board is down, I can actually slip my hand in between the bottom of the 'U' and the bottom of the trunk(boat)[ which is actually a really, really bad idea, almost lost a finger]. So, is this a late model redesign, has anyone seen this type of board?

Thanks, R
