The first step is to unstep the mast, you really can't adequately make the repair with the mast in place. That will reduce the compressive load on the repair area, then wedge or otherwise gently lift the structure back up to it's correct height. Now cut out the rotten section of the compression post and splice in replacement wood. Lifting/wedging against the underside of the cabin top may bring everything up with it, but it may also just lift the cabin top and separate it from the structure underneath. You may need to find a way to attach a setup to your bottle-jack that will hook under the bulkhead/cabinet structure and push it up from the bottom, then insert a temporary compression post alongside the permanent one to hold everything up while you make repairs, then lower the structure back down onto the new base. I have rebuilt structure under the compression post on a couple of boats, but neither boat had a bulkhead there, just the compression post, so I'm not sure about how the deck and bulkhead o the CAL 27 are connected, plus different boats are built different, so even if lifting the underside of the deck would lift the bulkhead with it on one boat, doesn't mean it will work for all boats. You could try it, maybe it will work? But either way, the mast really needs to be unstepped first to take the load off the area.

Re: [Cal_Boats] Re: fixing the compression post

GEORGE BARLOW2016-06-23 01:57 UTC
I’d go with the loosening of the stays with the mast up as a first try. When I removed my Cal 28 compression post, the rig stood up fine. The dead weight of the rig was supported fine by the deck with the bulkhead providing most of the strength. You could put a padded 2 by 4 supported by a bottle jack as a sister and it would pick up any sag. I eventually took the rig down because I didn’t trust my rig to stand up in the spring windstorms we have in Texas and I didn’t want to harm any boats in neighboring slips in case it fell.
