One of the recommendations on the survey for Solar Wind was to epoxy saturate the mast step block at fracture.
Can anyone recommend the best product and method to do this?
I was thinking of applying a very loaded brush to the fracture and the area to the left of fracture where wood is visible.
Should I also consider drilling holes on the top, further forward, to saturate more of the block?
Do you know whether Catalina used an epoxy treated or just plain piece of wood for the block on the 86's?
Thanks all

West System epoxy can be thinned to near water-like viscosity with acetone.
Do you know what kind of wood the block is made of? Some woods won't take up much epoxy.

Daniel,

What is the mast step block? Is it the chunk of wood used to stiffen the part of the interior pan (dinette seat) that the compression post sits on?

My boat has a standard layout. The picture I posted (which my ignorance prevents me from making any larger than 72 x 96 pixels, even though I'm trying)is looking forward in the bilge. The fracture that the surveyor found bisects the orange circle in the picture. If you can make it out, it is where the vertical forward face of the bilge meets the horizontal face of the boat. The surveyor said the boat is made with a piece of wood transmitting the weight of the mast to the keel.
Has anyone had to do any repairs in that area?

Daniel,

Try as I might, I can't figure out what is in the picture you posted.

Here is a picture I borrowed from another topic showing the stiffening block under a dinette seat.


Although the traditional layout is obviously different,...is this the block you are talking about?

Here (hopefully) is a bigger image that will show what I'm talking about. The orange circle is a flashlight shining on the bilge and forward on the interior of the boat. The wavy brown line that almost completely bisects the orange circle is the fracture. To the left of the fracture you can see an almost round area that shows the wood of the block, I think.
Thoughts, gentlemen.

Dan:
Thanks so much for posting the full size picture for me.
Now that it's properly posted does anyone have recommendations as to product and method to do the job?
As I mentioned, the area shown is the topmost, forward part of the bilge.
Thanks all

There is a product called Git-Rot a penetrating epoxy that permeates water damaged wood and restores its strength. it might soak into the crack shown in the photo. Once cured you could prep the surface and lay in several layers of glass and resin to strengthen that area.

From the photo I'm not sure where the mast step is but the crack shown could be repaired using the above method.
