I'd suggest looking at the Grampian Marina website at http://www.grampianowners.com/
It used to be the Sailnet Grampian mailing list was very active, but when Sailnet shut down, people went to four different forums, and discussion got spread out among them. The Grampian links page on that site points to the different forums.
I don't know about the 26, but at least on their bigger boats the centerboard started as a piece of mild steel plate with filler and fiberglass around it to form the streamlined shape. If water gets in to the steel plate, it will rust, expand and crack the fiberglass covering. In cold climates, water freezing inside causes the fiberglass to crack. You see this a lot in rudders, too.
Repairing a cracked centerboard shouldn't be too terrible a job. Look for information on repairing cracked rudders -- it's the same type of job. Even if you have to build a new one, a welder can cut you a new steel plate, then you apply Bondo to build up the shape and fiberglass over it.
The Grampian mailing list (http://list.sailnet.net/read/?forum=grampian
) has been silent for a while. This might be a good question to ask to get some activity going again.
Of course I'm biased, but I'll recommend the G26 as a great economical cruiser. Grampians weren't fancy boats, but they were certainly solidly built. At my marina there's a G26 still sailed by the original owners -- and that's at least 30 years now.
