Found separation of fiberglass head wall from interior hull


Sara Roberts
 

Recently discovered in our onboard head a separation of fiberglass wall at the basin area from the interior hull.  I didn't find anything in past group files regarding this.  The 12 inch length by 1/4 inch separation on our 1984 Cat 30 and is viewed through the teak door on the forward wall of the head, the separation is on that wall where you have access to the through holes for raw water for the toilet and sewage disposal.  The separation seems to be a tag that supports the head / basin wall to the interior hull.

Surely someone has experienced this and is it a matter of applying a fiberglass patch to this area? thanks

A pic is worth at least a couple of words 😉

If it is on the hull, then and not seen from the outside, then someone has done a patch job from the outside.

If it is on the interior fiberglass liner, then not to worry about it.

What hull # is she?

Here yah go. 
It's not fatal, just stresses that loosened up the tabbing on the (small cubby door) wall of the vee berth port bunk. 
The hole on the left is a weep hole.



For context, this composite is inside the liner, under the port bunk (you can't get there on yours) looking aft ( you can see to the inside of the frame of the access door.)    I highlighted the loosened-up tab.  Further context -- the pencil is in the weep hole that drains that cubby storage area.



The loose tabbing is at the lower left, inside the cubby (louver door is removed) at the corner right at the bottom of the head seawater hose loop.




I haven't given it much thought/inspected it closely enough to decide exactly how, but my ** guess** is some permutation of :

  * cut away the loose tabbing (multi tool or angle grinder w/ 1/16" blade) and re-tab it.
~ or ~
. * open up the margin underneath the loose tab (either method above) work resin/microfibers under the loose tab using a plastic putty knife to re-adhere it to the hull.  Or gingerly drill a line of holes thru the tab and inject the mix underneath using a syringe.

My middle photo is misleading -- I didn't notice that I had lost my bearins' as to what's up/down/sideways.
I thought the two pics were pretty much contiguous and facing aft, but they're actually facing different directions.

Here's the corrected context showing the proper orientation and the loosened tabbing:

I have a 1984 Cat 30 with separation in exactly same place. When I bought boat, inspector told me about it, so I am guessing he knew to look for it. He said not crucial but should be fixed. It is still on my to do list 3 years later. 

Looking forward to suggestions. Hardest part is going to be access - getting my two big paws and tools/materials to where they need to be through tiny access hatch - and be able to see what I am doing!

Bill.... our issue is on the interior fiberglass liner. thanks for everyone's input.    It will be hard to access but opening the tab slightly and then fiberglass a new connection.

>>> Hardest part is going to be access <<<

You could take the plunge and install a cubby door. Just a simple one- it wouldn’t need to be as involved as I did with a drawer above.  Just a frame/door. 
Guarantee you’ll never regret having the cubby storage there.
