Thanks Ed. The story at http://www.cncphotoalbum.com/doityourself/maststep/maststep.htm is informative. Someone who owned the boat before me had already cut a rectangular hole in the cabin sole next to forward port dinette bench, and fashioned a thick wood block to fill the hole and span the two cross supports. They just didn't go so far as to rebuild the cross supports. The above story looks like a reasonable way to do it.
So when your step failed, what happened? Did those timbers, and the floor pan, just break, causing your mast to drop 6-9"?

My C&C 30 Mk 1, Hull 19(?) had the step fail on the 1st sail. I was in Mobile Bay at the time of failure and had the step rebuilt by a professional who was the Boatwright for the US Olympic teams in China and England. The rebuilt the step is similar to the description in the Photo Album, differing by filling in the gaps between the cross supports with epoxy/filler. Total cost in 2006 was about $1200 plus the cost of mast unstopping/ stepping. The repair required cutting out part of the cabin floor pan to allow access to glass in the new supports.

The aluminum step is screwed onto a heavily sealed wood block ~12"x6"x2", which is in turn screwed onto two short timbers running athwartship which I'm sure are intended to take the load of the mast and transfer it to the hull. Those two timbers have been wet and appear to be a rot risk. The PO fitted a heavily sealed wood wedge down into that lowest part of the bilge between the floor timbers, to further support the block under the mast step. My concern is that the wedge will transfer load from the mast onto the top of the keel instead of to the hull via the floor timbers, and thereby contribute to separation of the lead ballast part of the keel from the fiberglass keel stub i.e. the "C&C smile". Do you think this is a legitimate concern? Any thoughts on how to otherwise reinforce the floor timbers or distribute the mast load to the hull? Also that wedge was sitting in bilge water because the automatic bilge pump float switch is a bit aft and a bit higher. Both the automatic and manual bilge pump intake tubes are down there in that lowest part of the bilge, but the manual pump must be more effective at removing that water because of the float switch location. Thanks in advance for any comments.
