Possible tunnel damage

I've got a 63 Sakonnet that I've completely stripped down to do some major fiberglass repair. I noticed when I was hosing out a couple decades worth of grime, that the tunnel seemed to be oxidizing away. It appears to be an aluminum tube, surrounded by fiberglass. How serious is this. It seems that even if the aluminum tube is compramised, the fiberglass tube would still remain watertite. It still looks like it could used some repair where the tube joins to the well. Just a little concerned because a leak there could lead to some serious problems later on

"tunnel" to me refers to the gunnel from console to transom.
if you mean the "drain tube" it is copper and they do corrode and it will cause water to seap into the hull.

The tunnel on the older 16's are made of an aluminum pipe or tube as you note. The new boats use (and have used since the 1970's) a tunnel made of PVC pipe. I do no think the tunnel is surrounded by fiberglass but rather the ends are overlapped with fiberglass but the rest of the tube is surrounded by foam.
If the aluminum tunnel in you boat is corroded out then I'm not sure there is much to be done, nor is there any easy way to reseal the joint between the aluminum tube and the fiberglass liner. Some polyurethane caulk would probably be the best selant to use on the tube ends if you were to try.
I would think an old boat with an aluminum tunnel would not be a good candidate for moorage in the water.
