Sea Trek "Trouble with tabernacles" The beginning.

The problem may be that the supports under the cabin sole have rotten away. Normally, there should be a floor* or stringer directly below the compression post or bulkhead that transfers the loading of the compression post/bulkhead down to the keelson/hull. In many cases these were made of glassed over wood or wood, and if the wood has rotted away, the glass may not have been sufficient to withstand the loads and has collapsed. The cabin sole, much like the interior liner on more modern boats, isn't in direct contact with the hull and there is a gap between the two. You're probably going to have to remove the cabin sole and look at the stringers and floors under it to see what shape they're in.

*BTW, floors on a boat are hull stiffeners that run athwartships, while stringers are generally hull stiffeners that run longitudinally to the hull.

It sounds like i will have to put a post in there. The sole is sunken in underneath the post in that area, creating a small bowl that pools with water. How is it possible that the bulkhead and small post could indent the sole of the cabin. Does that mean the sole does not sit directly on the cabin floor?
How do i go about making the post go thru the cabin sole to the keelson?. I am not able to visualize the architecture under the sole. I have never seen a picture or graphic of that area. My only thought is to cut and remove a section of the sole to accomadate where a post might go. One of the experienced sailors in our club suggest simply putting a post there and mounting it to the sole. I wonder if the sole lies directly on the keelson?
Does anyone have a series of photos. or is there a book with this repair explained?
I am becoming somewhat alarmed.

Re: Define "a good old fashioned refit"

Thanks for all the advice. I will look up the bulkhead replacement on the catalina, and then formulate a plan of attack. I already have some ideas. As things progress, ( or regress) I will post here.

Hi folks,
thanks for all the advice. I began a new thread for same repair under ask and oday owner. the reason was were were getting brand specific regarding 'what the heck is under the compresion post'. I have examined as well as i can and have come to the conclusion that the floor is sound, but the bulkheads and post have to be repaired or replaced. I am in need of some guidance on this project. does anyone have any pictures of list of steps regarding bulkhead replacement and repair on an oday 26?
any help would be greatly appreciated
keith

could you go to That sinking feelin'..trouble with compression post" that is where i take up this topic, since we began to get maker specific with the project regarding what was under the sole. I have posted new pictures regarding the bulkhead, and the deterioration at the chain plate attachments. the bulkhead will need to be dried out and the area around the chainplate reinforced. I would like to get ideas for doing this
thanks
