HELP!
    I dropped my keel this past Spring.  I removed about a 1/2inch of corrosion and replaced the cable.  After reading information on this web site abput dropping the keel, I realized that I may be missing parts. When I dropped my keel, there was no crash bumper or evidence that there ever had been one, also I never realized that one was required (until I read that this is indeed a part of the keel).
     We put our PD in the water and have sailed several times, but right from the beginning the keel was moving and thumping. I began to realize that something was not right with the keel and while we were sailing the cable broke.
    I think that after removing the 1/2 inch of corrosion that it left way too much play in the keel.  Do I need to add polypropalene shim sheets?  Would this solve movement of the keel?
Curantly, the cable being broken and no crash bumper, the keel is banging against the hull.  (Big trouble, I guess) [Sad]

I am no expert but I think that if you replace the cable and crank it up a few turns until the cable is under a good amount of pressure you will find that the banging will probably stop.  This seems to be a common swing keel problem.  Welcome and good luck!

This summer I removed my keel and had it sandblasted.  My hull is 310, and though I have read of earlier PD's having a foam crash bumper built into the keel, my keel did not have one.  As soon as I get the keel back in the boat I will be publishing some pics if anyone is interested.   LL

Well, it has been ten years sinced we sold our Dawson (before Parker/Dawson) but we still recall her with the utmost affection. We moved to an O'Day 37 center cockpit, which looks like the Dawson's mommy.

Anyway, the issue is keel crash absorber. Ours was also missing. We just epoxied a piuece of foam we found lying around into thje space, trimmed it to fit the form of the keel and then glassed it over with woven mat and epoxy. Worked just fine. We also broke the keel pendant at some point but it was easy enough to replace with the boat hauled on stands.

But I really hated that iron keel. Corrosion.

Knotshore, I hope you have resolved your problem by now..The keel CAN be drawn up by slipping a rope noose around it, feeding the free end up through the hole in the centerboard trunk, over the pully and onto the winch. It is possible to reach up into the trunk with the free end of the line using just a snorkle and mask. At least then you can get the boat back onto the trailer. You can also replace the cable by intentionally beaching the boat and pulling her over on her side until the keel can be lowered enough. And yes, polypropylene sheets are used on each side to shim the keel and stop it from moving around. Maintaining the cast iron keel is a constant battle.

Excellent idea, beaching the boat and pulling it over.  I need to scrape and paint my rusty keel and while I won't be able to get every inch of it, it should be much better.  THanks!

When I did this, I disconnected one of the outer shrouds and used this as the "pull-over" line...This puts quite a load on the one inner shroud holding the mast up, but it held OK. I have also gone up the mast to the spredders and tied a line at that point. I used a Danforth anchor hooked into the beach sand and a come-a-long to pull the boat over on her side. It did not take tremendous force to roll the boat over.
   To refloat her, I set a second anchor 50' out in the water with a single pully (snatch block) attached to the anchor so I could pull from the beach. At high tide, we pulled her in stern first. The prop is high enough to stay out of harms way..[8D]
