Hi Tradioshow. I have a new-to-me 1979 Hunter 30 and I have flooring problems as well. Seems as the PO did not take care of the boat and apparently lots of water got into the cabin floor and delaminated all the edges. It seems to me that the flooring is laminate with 3 layers, top layer is very thing teak and holly, underneath that is a thicker "plywood" layer and then under that a very thin layer of an almost cloth material, all of which is held down by big glue (sticky but pliable) smears. Nevertheless, I originally said that I was going to take up the first layer and fix it, Well that was impossible because the damage had gone all the way through all layers in some places (large areas) and left large humps. So I began the task of removing the flooring last week. Like you I was afraid of what I might find. I am attaching pictures of the beginning and then "after I cleaned up" area that I started. It is all gelcoat fiberglass underneath the wood. The only problem (I think it may be a problem) is the bilge cover. It appears that it needs to be raised up the thickness of the original floor, so I haven't quite figured out how to resolve that issue just yet, hence the reason I stopped removing where I did. I have read several other Hunter 30 owners stating that they had flooring problems as well and they had used a "teak" vinyl plank, tongue in groove, flooring from Home Depot to replace their damaged floor. I did go search out the material and it is about $25 for 24 sq ft and I will need 2 boxes (at least) and then the glue and patience to install it. It seems (don't know yet) that the vinyl planks are pourous enough to flex in the areas that need it (in front of the sink, etc). Then I will remove and diassemble the bilge cover and redo it in the plank material as well. I suspect that I will still have to use a rug in order to have a non-slippery surface. Or maybe I will come up with some other anti-skid plan. Hope this helps! Good luck and let me know of any secrets you might find as well.

Oh and by the way - if you do pull up the original floor, there are lots of teak plugs you might be able to use in other places as well. That's what I'm doing.
