Re: [Cal_Boats] 1968 Cal 25, need infomation

Don, Your Cal 25 is a Bill Lapworth design; Martin's latter day Cal 24 is a Raymond Hunt design, and therefore may bare little resemblance. My Cal 24 is the original Cal, and the mast is held up by beam which appears as a curved piece of 3"X4" supported on both ends by a plywood bulkhead/knees and the plywood overhead which is encased in fiberglass above and below. My shrouds are glassed into the hull, the Cal 25's are tied with straps into the plywood bulkhead, and these straps, or chain plates, egress thru deck, where leakage may occur (look for stains on the plywood bulkhead). It's raining today, and I'm afraid my tabernacle which is held into the beam by wood screws, may be leaking into the plywood, as I see dark stains permeating the wood above the clear coated fiberglass above. A number of years ago I tried to unscrew the screws, but they are corroded solidly into the tabernacle and into the wood beam. Perhaps I should get more aggressive, soak it in penetrating oil, heat it with a torch, (wooosh!?) and smack it with an impact wrench until I strip the slots of the screws and then give up in disgust? During my last 'go-around' I chipped out as much corrosion as I could from the gap betwen the tabernacle and the dog house deck, then squeezed West Systems with Colloidal Silica filler into the gap. But since then the Epoxy has separated from the Aluminum, and my be leaks (groan!) so I may have to re epoxy the cracks and maybe encase the whole mess in silcone II or urethane caulk...before I end up with a horrible plywood overhead replacement delema. (double groan). So far my overhead is still solid... But all it takes is a few spores from the wood rot god to do me in. BTW down in Long Beach some of the Cal 25 fleet have rehabed their deck beam using a pre-fabricated aluminum beam, one of my deck mates did it and it worked out pretty well. In any case it is a real project...but worth it unless you want to trade you Cal25 in for one that's still intact. Another fellow here redid the whole Cal25 overhead plywood from inside. It's a pretty difficult, messy job, but do-able with fortitude. Charlie Husar is this sites resident Kahuna of Cal 25 rehabilitation, having done or supervised 15 or more of them.

Other than the rigging to the chain plates holding the mast in place, the direct through the hull support on our boat is down through the top, onto a 3X3 cross beam under the Saloon ceiling, which then is supported by two 2X2 supports down to the hull line. The 2X2 supports are held in place by another 2X2 between them on the interior floor of the hull, and from the sides they are supported by the bulkheads which of course go out to the sides of the hull. (I know all this only by experience as we had to pull all this wood which was rotten out of our Cal 24, and this weekend are starting the rebuild). Basicly there is a "Box" of support connecting the saloon ceiling with the mast plate down through the hull. I am sure (by now after taking everything out) that the other full bulkhead, and the two partial bulkheads have a lot to do with the support structure as well. Martin Klos

Jerry, as a purist, I stay with the wood. As I pointed out, the exterior mast pedestal is often at fault due ill treatment in the past. Yes, the redeck job is an effort, but I have survived with only minor brain damage. Sure went through a lot of shower caps. It is unfortunate that early owners of the 25s (and maybe even the manufacturers) were unaware of the critical maintenance items on the boats (particularly the critical caulking points. Once the boat is rehabbed, and the owner aware of the maintenance, the boat is fine. My "Chicken Little" was redecked, rebeamed, repedestaled and resterned over 20 years ago. and she is very solid in those areas today.
