Morgan 22 Centerboard + Swing Keel Restoration

It''s time to restore the 1968 morgan 22 I have. After cleaning the small ecosystem that built up in it after 15 years in the FL jungle, I need to focus on the centerboard. The old centerboard has rusted, expanded, and split, so it doesn''t fit back into the centerboard trunk easily. I''ve decided to refab one using 1/2" aluminum + 1/4" stainless bars near the bottom for weight. This is the first time I''ve worked with these materials, and I''ve glued some high density boat foam to it & will sand this into an airfoil shape to fiberglass over. Does this method sound OK? Any tips?

After the refab, I''m going to replace the winch, cable, and pulley system to lower and raise the keel. Does anyone know if Morgan/other manufacturer sells replacement winches, pulleys, (and more importantly) the piston system (rubber elbow, piston, and pack nut) attatched to the elbow which leads to the centerboard trunk? Are there alternate methods I can use?

Also.. another stupid ?: The gel coat along the hull appears to be slightly blistered. Is it necessary to sand the entire hull down to the glass & coat it with a few layers of epoxy before painting it again? I''d like it to be able to sit it in the water for at least a couple (2-4) years without worry of damage.

Thanks,

Brice

Morgan 22 Centerboard + Swing Keel Restoration

I am not a repair expert. That said, I have over the last 25 years successfully repaired delaminated decks, small blisters, cracked rudders, reinforced weak decks etc.

I think your plans sound reasonable. I do know that you run the risk of allowing water to get in between your foam and the metal inside on the CB. The metals you have chosen will not be greatly effected and were they to be, I am sure you would see obvious signs ofd failure in your fairing.

Blisters: Gel coat blisters are not serious if they are in small enough numbers that you can pop, dry them, and fill them by hand. Be reasonably sure they do not go into the laminate below. You say "along the hull" and that is a little unclear. If the blisters are located to a small area, I would say that is a good sign. I used to get 15 or 20 gel coat blisters each season along my hull to keel joint. I opened and dried them and then filled them with West. I have not had any blisters for 4 or 5 years. I would certainly go this route for now and see how it works.

I wouldn't mix stainless and aluminum. You'll be setting up a galvanic corrosion cell internally...and the aluminum will fail rather quickly if any saltwater gets into the centerboard. It would be better if you used stainless throughout.

As for the blistering.. if you pop the bubbles, and they are dry inside, they aren't osmotic in nature. If that is the case, just pop them, fill them with thickened epoxy and then fair and paint with a barrier coat. I'd recommend four coats of Interprotect 2000e, two gray, two white, so you can ensure good coverage and know if you've sanded through the barrier coat in the future. Be careful to continually mix the barrier coating, as the "micro plates" tend to settle out if you let it sit.

If the blisters are filled with liquid... they are osmotic in nature and you'll need to sand and then dry the hull out before doing anything else.

Make sure the centerboard's profile is symetrical and a decent NACA airfoil shape, or the boat will have performance problems.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Re: Morgan 22 Centerboard + Swing Keel Restoration

Hi, I just got a Morgan 22 last week. It had sat in fresh water unused for several years, but is in surprisingly good shape from what I can tell so far. I dove underneath it for the first time yesterday, and the centerboard was straight down, and moved freely. I didn't see a cable anywhere, or a place to attach one. On the Catalina 22 we had as kids it was very obvious, I remember diving down and replacing it, and the winch was self explanatory right there in the companionway. I was focusing on cleaning when I was looking in the bilges, so I didn't really assess what was there, but I did see cables with tension on them.

The keel itself felt to be in great shape, and even if I just get it to stay down that would be fine, depth isn't a concern in the lake where I am. I just have no idea what all there is to the system on that boat, and what of it I can see and get at, and what I can't. Does the keel just stay down with its own weight? Or does something hold it in place, I couldn't really judge if it would get pushed back if you really got going.

Does anybody have any info to get me started and to tell me what to look for?
