A a rather large section of a dock mate's deck core was soggy, and his fix was simple, cost effective, not too terribly invasive and permanent. He drilled a small hole every inch or so through the deck and the core, but not all the way through. When the wood shavings coming out of the holes was dry, he knew he had gone far enough in that direction. He covered the deck with plastic kept away from the deck to allow air flow. He then heated the underside of the deck with an electric heater to drive the moisture out of the core. I don't recall how long the drying process took, but it was more like weeks, not days.
When the core was dry he then injected epoxy into the thousands of holes, faired it, painted it, done. I stood on it after the repair and it felt rock solid.
Good luck,

Larry,
I think you're going to have a pretty tough time trying to get the Git Rot (assuming that is what you plan to use) to penetrate six feet laterally of deck, without opening it up to get it dry and have a decent base for the epoxy. Do you think cutting the deck skin, opening it up yourself, and then replacing it after you've treated the core might have better possibilities?
Best regards,

Hi Rory,
Well, its all speculation as to wether it will work or not. Admittedly,
getting the epoxy to travel through 6 feet of decking seems like quite a
bit. It is very thin epoxy (water like in viscosity). If after treating
it and sounding it, it still has voids, I figure I will just get a very
small drill bit and drill some holes through the decking and inject the
epoxy through a siringe.
Its a gamble to be sure, but I'm rolling a weekend of work and a hundred
dollars against what could be a 5K job. Given that a 30 year old C27
might only be worth 5K, I don't see the 5K job as even being a option.
I don't even think that MY boat even needs it, but to please the surveyors
and future buyers, its probably money and time well spent.
Hope that helps,

I think your success will be a function of how far the epoxy has to
travel, in a small area drying process and saturation may be effective.
The rotten core on this boat is wide spread about six feet from front
lower all they way back to cockpit. This will require removal of liner and
layer above to remove large portion of core. The Estimate is 5K.
My biggest concern is how strong this area will be relative to a
properly maintained deck that is dry, even with the high dollar
professional core replacemnt and refinishing.

Hi Rory,
My boat has much the same problem. Heres my plan for dealing with the
problem. I plan on doing this during spring haul out.
First, I will remove the interior cabinetry to allow me full access to the
hull to deck joint from the interior cabin.
Next I will remove the deck (not cabintop) chin plate bolts. I will then
duct tape up the interior holes, or plug them with a dowell.
On the exterior chin plate bolt holes I will affix a shop vac and blow low
pressure air through the deck cavity in a attempt to dry out the interior
decking. Maby a hair dryer would be better.
Next I will duct tape up the interior hull to deck joint where in the past
the coring has seaped out. Any place where coring has leaked will be a
place where the thinned epoxy will leak. Duct tape this well.
Next I will use this product:
http://www.jamestowndistributors.com/to;ID;,Epoxy...Adhesives,Smith...Co..Epoxy,CPES.Clear.Penetrating.Epoxy.Sealer
My understanding is that it WILL treat wet coring (to some degree). It
contains some chemicals that will react with any moisture in the wood and
dry it out. It is very thin so it should flow through any deck cavity. I
will basically fill up the deck cavity until the epoxy is at the level of
the side decks. I'll let it dry, then re-drill out the chin plate bolt
holes.
Then re-sound the deck with a hammer. If any voids (probably trapped air
bubbles) still sound in the decking, I plan on drilling very small holes
and then injecting the CPES with a seringe. Put it all together.
Done.
Call it a couple of hundred and a weekend of work.
Hope that helps,

During survey of 1988 Catalina 27 side deck around chain plates andDixie Chicken is FOR SALE: You can view the boat at:
further aft about 4 foot section determined to have either delamination
or
water intrusion.This was indicated while deck was being sounded, or hit
with small hammer every 6 inches or so.Refereed to specialist, to have
deck inspected by drilling 3 inch holes for further inspection and
cause.
Then repair scheme to be determined.Has anyone been through repair
schemes, one is to inject epoxy if core is dry and delamination exist,
the
other is for deck removal and core removal and replacement, with
required
refinishing.The sounding process seems fairly straight forward on deck
at
least,and I would considering doing myself in future before expense of
survey haulout etc.
Otherwise the boat is above average for year.

Thanks for the link. This may make changing coolant much easier.
