[C38] Head Liner Joining to the deck

[Phil Gay]

I think that a gap between the plywood core and the hull liner around the
windows is common.  When I removed and resealed the fixed ports (windows),
the plywood was really delaminated, but it wasn’t wet.  As mentioned before
most of my window leaks were between the frame and the glass.

 

The places inside the boat where leaks have been evident are around the
mid-lower chainplates, the bolts that attached the aft lower chainplates,
and in a couple of places inside cabinet on the port side of the boat.

 

When I removed the chainplates for sealing, I routed out the soft wood and
sealed around the opening with thickened epoxy.  I am hoping that this will
have some lasting benefit.  I had to replace the chainplates before sealing
around them and it was difficult to get sealant very deep into the crevice.
I am hoping that the modern sealants will bond to the surfaces that I
carefully cleaned.  I still plan to cover the boat this winter.

 

Good luck.

Thanks Phil, 

 

That is what I suspected, I remembered your experience with the leaking
chain plate and the water dripping into the galley cabinets.  What has me
puzzled is that on Peregrine there is absolutely zero sign of any water
damage anywhere inside the cabin.   This has me wondering if it is escaping
the woodwork and running down the back side of the woodwork against the hull
and into the bilge or if the laminating of the liner to the deck created
pockets that trapped it near the window.  I did notice when removing the
windows that there was about a 1/8 gap between the wood and liner and that
none of the windows leaked (except one).  The window putty they used to seal
the windows was dryed and cracked around some of the corners, so maybe the
water was leaking past the window down the frame and into the 1/8 opening
being trapped in pockets made by glue lines joining the liner to the hull.
Oh BTW one of my chain plate repairs started leaking again, I spread a small
amount of silicone on the cover plate, chain plate and screws and over  the
sikaflex bead between the deck and plate.  It seems to be holding and
passing all the hose testing for the moment.

It looks to me like the headliner was molded separately from the deck.  When
the deck, plywood and liner were joined together  voids were impossible to
eliminate since they didn’t use vacuum techniques common on high end boats
today to pull the resin between the layers.

 

After taking the aft lower and mid-upper chainplates out of Que Linda, I
found noted the layers in the deck.  There is, of course, a layer of ¼ inch
of fiberglass on top, with a ¼ inch layer of wet, soft plywood below.
Beneath the plywood, there was a ½ inch layer of very dense, hard, dry wood.
The inner hull liner was bonded to the underside of this mystery wood.  The
place that water channeled in the deck core was where this dense wood was
butted together.

 

The hull liner runs parallel to the deck until it approached the hull, then
it turns down for about 2 inches before it ends.  On Que Linda, water ran
from the mid-upper chainplate outboard to the edge of the hull line then
dripped into the cabinets aft of the chainplate.

 

Unfortunately, I couldn’t get good photos of the area.

Hello all, 

 

I am curious on the head liner construction/join to the deck?  Is there
space between the two or are they sandwiched together?  I recently removed
all the windows and resealed them, in the process I removed the venetian
style blinds that were inside the cabin.   These blinds are attached at the
top as you would expect and have a wire running through the blinds which is
attached to a screw that is fastened in the side wall below the window.
When removing the blind on the port forward window I removed the screw
holding the wire in place and water poured out of the hole for 1-2 seconds.
I am trying to visualize what type of cavity is behind there to hold water
and how large it might be.  I would think that if there is a space any water
should drain outboard and then against the hull and into the bilge.   Or is
constructed so that there could be any number of pockets depending on the
glue seems holding it to the deck.    The area where the hole came out is
very close to the aft lower chain plate.   Thanks.
