Not all DS2's had/have mast hinges - The Red Witch didn't have one until last Summer, and someday I'll look back on that, laugh nervously, and change the subject ...
Anyway, I think it might be useful here (and this is just general sailboat info) to come to some clarification about what the difference is between a mast hinge and a tabernacle, because I think a lot of folks get the two confused:
A mast hinge is usually just that: simply two plates that are bolted to the bottom of the upper part of the mast and the top of the lower part. The mast is cut at some point not too far above the partners (where it comes up out of the cuddy roof), and the hinge is attached. The upper part is connected to the lower part by means of a pin or pins inserted through both to hold them in place, and the mast is raised.
A tabernacle is like a hinge, but is usually affixed right at deck level, and may or may not incorporate any below deck support. Also, it has slots, instead of just holes to accept a pin(s), that aid in the setting of the butt of the mast into it and raising same. There is no plate on the upper part of the mast, rather usually just short pins protruding from the sides of the mast butt, and once it's up, they're locked into place in the slots.
OK, so that's my lesson for tonight! Sorry, just thought I'd clear that up - any questions, just see me after class ...
