Started tearing into the bilge today.
My first thought was to dry it out with this series of holes.
After a few days more and more water came in, so I decided to completely open up the bilge based on info from the builder.
First the glass was stripped off exposing the plywood
form. Notice the wood was starting to rot
on the lowest part.
Next the plywood was removed as far as I could effectively reach. What you see here is the concrete that makes up the ballast.
This picture is looking aft into the bilge showing the very limited access.
This shows post demo looking aft. Note the concrete tapers off under the plywood form, probably due to not enough vibrating during the pouring process. This caused water to hold in what was supposed to be the highest part of the bilge. Also you can see ice back there, it's cold here.
So for the next few weeks or so she will sit like this with the heater running 24hours a day.
The next question is how to rebuild
the bilge. Since I can't get the last of the plywood out I'm planning on filling the void underneath with more concrete, that's what is supposed to be there anyway. In order to make up the 3/4" from removing the plywood I'm thinking of more concrete to get the dimensions back and build the proper slope. After that is where I need help. Reglass over the top or use a two part epoxy
putty like Gluv-it? Or maybe both then a few good coats of bilge paint
. I don't want to do this again.
A lot of future problems will be avoided if I reroute the icebox
drain. Maybe into a small holding tank
with an automatic bilge pump
