Don't panic. I just went through this with my boat and did a lot of research on the issue. This is normal for anyone who owns an iron keel. Use 5200 or 4200 (probably better as it sets faster) on the joint. The keel will work as you sail so you may need to do it every time you haul out. It is just the curse of the builder and is one of the one weak points in the design. You could get the yard to move the keel block to the aft of the keel, thereby opening the gap up a bit more. You could then get some sealant in there further and it should last longer.
