Epoxy encapsulation
Great question Joe. I completely agree with your encapsulation strategy. You are creating something that can no longer be considered just an O'day. They, like many many other builders had to make choices since they were offering a sailboat intended for the mass market. The fact that we are all here talking about our boats 25 to 30 years later tells you that they did a very good value engineering job. But for us who have dismantled much of the boat, we must take this opportunity to do what O'day could not. Removing and sealing off core as we re-bed deck hardware, redesign headline panels (coming soon). Some upgrades like LED lighting because technology changes. And of course epoxying all the wood, because we have the chance and we know it's the right thing to do.
Now specifically the counter top, No, I will not be coating it even though I know the top will someday de-laminate. I'm no even using Marine grade plywood. My reasoning is this, De-laminating alone does not affect the counter top. Mine was completely de-laminated but it was not until I pulled up the sink I could tell. Being de-laminated saved me from tearing the complete cabinet apart. The Ice box throws a wrench in the way the cabinet and counter top are put together as tcwaltz explained. I want to leave behind the same possibly of peeling up the plywood one layer at a time. I will reassemble using tcwaltz's instructions and will protect the spot where water can come around the laminate into the plywood. But that is all. As for the cabinetry. YES, it's very valuable and would be very difficult to replace. That gets at least one coat of varnish on all sides. It is solid teak. I'm comfortable with varnishing it. Anything near the bilge gets epoxy.
This brings to mind one topic that I will (and I hope you will too) completely address when we get these boats all put together. O'day Quality: What I have seen, I give O'day High marks. Each peice of cabinetry is press fit then secured by screws. Its offen very difficult to remove some of the cabinetry for this reason. Sure, the hull tabs are screwed (not through bolted)to the bulkheads but has any of us found this to be a weak spot? What I see in my boat is Value engineering. The boats were built for the market intended. Now Joe and I can re-evaluate O'day's value engineering in a new light. With a different purpose, we will reach different conclusions.
