I think what you are describing is the "Mast Step Casting," $16.50 from D&R Marine. If the mast steps directly too the keelson, the casting is bolted to the keelson. If you have a hinged mast, there are three castings used. The first one is on the cuddy floor to hold the tablernacle post. Another is riveted with aluminum rivets to the base of the mast, and the third is riveted to the top of the tabernacle post. A 2-part stainless steel "Tabernacle Hinge" goes between the two castings -- one hinge plate on the mast, the other on the tabernacle post. The whole assembly is about $85.
