So this is it,
I doing some winter service on my boat, new deck varnishing, some new hardware, then I found a crack under the mast step which I could open with pressing on it (by hand).
So I decided to open up the thing and had a look, this is what I found:

This is what I found under the mast step:

What surprised me is that the whole section in front of the mast step is not attached to the main beam (keel?).
Appart from the bulkhead at the mast step there are two other bulkheads. I was surprised that only one (continuous line in the next image) was attached to the double bottom. Where as the other (just like the front beam) stop about 2 cm before the double bottom:

Seems to me that the builder didn't understand the web-frange-joint principle. Yes I know it is more difficult to build.
So these are my thoughts:
- I will stiffen the area around the mast step and I'll have to replace the wooden elements with something that distributes the load.
- In addition to that I'm thinking of adding an additional bulkhead (long dotted line in the image above). I know this wouldn't be more than (invisible) cosmetics… Considering the condition of the rest of the boat.
One issue is the temperature in the shed. It's only a few degrease over freezing and I'll need to use a very fast hardener.
What epoxy should I use? West systems cost 2x more that others. Is it worth it?
