I am planning work I need to do this coming spring to repair the turning ball on the center board lifting tackle and also to the trailer.
I am far from a marina. I can hire a crane to lift the boat up, pull out the trailer, then set it back down on stands. I saw these photos in a previous post. I can certainly rig something like this up, but I AM VERY WORRIED ABOUT POPPING/FLEXING THE BALLAST TANK SEAMS WHERE THEY JOIN THE HULL. I could provide another cross beam behind the keel trunk, one in front, and then another at the back. I will have to climb into the boat as part of running the rigging and general fitting.
Any thoughts and advice? It will cost me several thousand dollars (3-4K?) to haul it to a marina and have the work done. But it's false economy if I break the water tank loose.
I think that's a C22 on the stands, they spec out at about 2,500 lbs. The C250 WB is about 3,500 I think.
I had this problem with my Catalina 22. The way I solved it was by putting jacks under the trailer frame and gradually jacking up the whole boat and trailer. I raised each side about 4 inches and then put 4 inch wide concrete blocks under the trailer.
When it was as high as I needed it to be, I built a wood cradle under it all, lowered the rig until the boat rested on the wood cradle, and then lowered the trailer down to the ground. I left the trailer in place, under the boat, to "catch" the boat, just on the unlikely chance that it fell.
I loosely followed the general design of the cradle on my trailer, which was similar to this one.
The wood cradle was constructed of 4 4X4 uprights with (as I recall) 2X10s between them, attached to conform to the hull shape. You can use more than 4 uprights if you think they're necessary to support the boat. I used 2 2X8s or 10s to tie the 4 uprights together at the base, both fore and aft and laterally, and then installed supports at approximately a 45 deg. angle from the top of each support to the base members.
I assembled most everything with 3/8" bolts instead of nails for two reasons. First, I thought they'd be stronger, and second, because I could mark the parts and re-assemble the cradle if I needed to use it again. It would also help if you took photos. (I didn't)
This sounds like a lot of work, but it really only took about 1/2 day to jack up the rig and build the cradle, and much less time to dis-assemble it and lower it.
I apologize if I screwed up the format with these photos, but they were the best photos I could find online.
If your trailer has roller bunks, let us know. There might be an easier way to accomplish what you want.
