I have decided that adding a tabernacle would facilitate better maintenance of HollyDay's mast. I have never had the mast unstepped since owning her (August 2001), and wondered what holds the mast base horizontally? Does the mast need to be raised slightly for removal? My thought is to buy some beer, have a few friends over and lower the mast similar to the way I did with my old Catalina 25, but the base condition concerns me.
Once down, some maintenance, scraping, sanding, paint and the addition of the tabernacle. I've checked the board postings and the Sources but cannot find a tabernacle specific for the CD25D.
Any help on either question is appreciated!

CD25D Tabernacle

Re: CD25D Tabernacle
The mast slips over aluminum casting that is bolted through the deck to the compression post. The insertion depth is about 2 inches +-. I recently installed a mast tabernacle on our 25D for the same reasons you mentioned. My choice was from Dwyer. The part# is 20-52. The price was $47.50 plus 7.00 shipping. http://www.dwyermast.com/MASTS/dm330.htm
This link shows what a simular tabernacle looks like with a casting installed. (Upper right corner) It consists of 2 heavy-duty plates, one fits inside the other with heavy pivot rods on either end. I utilized the casting from our boat. I drilled the required hole pattern in one plate for the deck installation and in the other plate to attach to the casting, which was inserted into base of mast and secured with bolts. With a pivot rod at either end you can lower the mast either direction. The nice thing about this tabernacle is the over all height increase is an inch or less so the standing rigging did not require replacement. An easy job with the mast down. Accurate hole drilling and bedding compound is all that is required. IF you need a photo I could send one directly to your email.

Re: CD25D Tabernacle
From the voice of experience...
Be certain to isolate the stainless steel hinge from any aluminum parts such as the mast step. Otherwise, over time, the dissimilar metals will corrode and the corrosion will warp the hinge so the pivot holes will become harder and harder to line up. An easy way to do this is to put a plastic sheet between the parts.

Re: CD26 Hinged Mast Step
This past spring I installed a Dwyer (#D2150) hinged mast step on my CD26, which uses the same mast as a CD25D. Following a procedure described in Good Old Boat magazine enabled me to self-step my mast while tied up in my well. Said procedure is so slick I can raise/lower the mast all by myself...although I wouldn't be drinking any beer at the time!
