It is just that everything else about the boat is perfect, layout, sail plan, size etc. Adding an extended keel would have been the more logical solution.

Replacing the centerboard with lead was a terrible idea that has probably pooched the boat's stability numbers. Cutting out the centerboard trunk and massively glassing in a keel stub, and then through-bolting a lead wing or fin keel would be a better idea...if a naval architect was involved. The scantlings of the hull might not support the forces at that point.
This idea seems so dodgy I would avoid this boat like the plague. Either have the original centerboard replaced (maybe with a design refinement that allows it to "kick up" if smacked) or just walk away.
Would you buy a classic sedan that had wooden wheels with iron rims on it because the owner "kept getting flats"?

Bad idea. I am willing to bet that a qualified marine architect wasn't really consulted on this issue.
In general, replacing the centerboard by filling the hole in the centerboard trunk with lead is not a good idea. The centerboard served a function other than ballast. It also served to add underwater lateral plane area, which helps the boat sail to windward. Losing that area may reduce the boat's ability to sail to windward drastically, and also affect the balance of the sail plan, which was designed for use with the centerboard deployed. Also, if it was a weighted centerboard, made of steel or iron, it is likely that the stability of the boat has been compromised a bit as well. With the board extended, the center of gravity would shift downwards, as the weight of the board moved down... that doesn't happen with the lead in the hole.

Irwin 41 CC
New to the forum. Greetings.
I have read all I can find regarding the Irwin Yachts, with many comments about the 37 and 38 footers. I am currently looking at the 41 CC. The use would be coastal and blue water (New Zealand, Australia and Pacific).
The boat has had one owner since 1983, who has lovingly looked after her. She was a centre board type, but after breaking two centre boards, it was removed and the "hole" replaced with lead.
The boat has sailed around the world, so I assume that it has withstood all the rigours of the oceans, however, seeing comments about pointing capability and some construction qualities, I am naturally being cautious.
I would appreciate any good advice, and or comments from 41 CC owners.
