[Public-list] Water tank problem on older boats (or, boat fal ling apart, ...

[Todd Redhead]

Actually what I found was a series of cracks on the inside of the tank down 
the 'seam' front edge of the hull.  What I had noticed was after draining 
all the water out of the tank and drying it out, when I came back the next 
morning there was water in the bottom again.  What was happening was the 
water was seeping through the cracks and into the tank.  I have left it open 
this winter and in the spring I hope to just paint on a layer of epoxy to 
seal off the cracks and prevent any further water from coming in.  Hopefully 
that will help with my little growth problem.

The port that I installed is in the top of the tank.  I has not leaked yet. 
I try to leave the tank full all the time as I feel the boat is more sturdy 
in heavy waves.  It tends to 'yaw' less and cut through the waves better. 
It has not leaked even when I have had her leaning way over.

I used just a standard 6" screw in type access port.  Mine is clear but you 
can also get them in white.

You should also be able to see the tank from under the 'beds' on either side 
of the v-berth.  Strathgowan has lift out access boards under the beds that 
give access to the underside area.  You should be able to see the top of the 
tank from there also.  You can also pull out the drawer on the port side to 
see the edge of the tank, I think.  Any of these access points should get 
you close enough to see where the water is coming from.
