Jeff,
 
Prior to owning "Dauntless" our 23 we owned a 17. I sold it to a friend of  
mine. When Jason took the boat from me he went bananas cleaning it up. It 
looked  great. However, when he tackled the inside of the cabin he decided to 
remove  everything and to go in there with a hose to wash the whole thing down. 
I 
was a  little skeptical about this approach as I was afraid water would make it 
to  places that might be difficult to dry. When he was finished the inside  
sparkled!...however, whenever you stepped on the cabin floor near the v-berth 
it  would flex and a little bit of water would ooze up through some stress 
cracks  that had developed right where the floor rolls up 90 degrees and 
becomes 
the  vertical side of the rear of the v-berth. Look for spider web like cracks 
in the  gelcoat  on the floor or long straight cracks running right where the 
floor  turns up into the backs vertical side of the v-berth. I think it's  
probably a fairly common thing and my opinion would be that it's not really a  
huge concern. What is a concern though would be to not let water lay there and  
to find out where the water came from and try to mitigate that. My 17 did not  
have any wood under the floor, rather, the liner sits almost right on top of 
the  hull itself. It turned out that there was a little space between the 
liner and  the hull where it (the liner) was flexing.
 
 After a lot of "what to do's"  we decided that water had slipped  between 
the hull and the liner (the floor is part of the liner) and the fact the  floor 
was showing some weakness and flexing was allowing it to act like a water  
pump pushing the water up through the stress cracks. Obviously the floor was  
unsupported in the area it was flexing. We decided to carefully cut the flexing 
 
part of the floor out in a nice square piece and lift it out. I believe Jason  
did this with a battery powered small rotary saw adjusting the depth to just  
what was necessary to cut the thickness of the liner. After lifting out the  
piece of floor it became obvious that there was somewhat of a gap between the  
floor and the hull itself making that area of the floor unsupported. After 
many  years (and sasquatch sized people like me stepping on it) the piece of 
floor had  just begun to weaken and was flexing. The first thing we did was to 
let it dry  out completely and to clean the area on the back side of the piece 
we removed as  well as the the area of the inside of the hull that was now 
exposed. Then we  mixed up a big batch of thickened West System epoxy with 
colloidal silica in it  to make it like peanut butter. We painted both the 
bottom of 
the floor piece and  the inside of the hull with Un-thickened epoxy first so 
that the epoxy could  penetrate the pieces and then took the peanut butter 
thickened epoxy and covered  the top of the exposed hull with enough of it so 
that 
when the piece of floor  was put back in place there was a solid bond between 
the hull and the floor (it  was no longer unsupported anywhere). We weighted 
the piece of floor down with  sandbags until it cured. Then we ground a taper 
all the way along the joint area  and laid in a couple of strips of 2 inch 
glass tape. That was sanded smooth and  the floor was back in, and now as solid 
as a rock. 
Jason never bothered to cosmetically finish the repair. Instead he just had  
a throw rug on it. I'd have gone on to prime it and paint it. You could 
gelcoat  it  but you'd have to have better gelcoat skills than I do! hahaha.
 
You do have to find out where that water is coming from. Could  anything have 
spilled inside and found a way to leak under the liner? How about  your keel 
lifting pendant hole? Had any really rowdy sails lately where water  could 
have been splashing up through the hole? How about through hull's? Check  the 
molded in through hull for the cockpit scupper and make sure the hose  
connection 
is good and tight and the hose is not dried out or cracked. And of  course my 
favorite...Rain water. On these older boats keeping everything sealed  can be 
a challenge and sooner or later you will need to re-bed the deck hardware  in 
new sealant. Not a fun job. We just got done removing the aluminum toe rail  
from Dauntless, cleaning it and rebedding it.....and we still have a little 
leak  when we heel her over and put the toe rail in the water! UGH!  Guess 
that's  part of the fun of it......yeah right!
 
Good luck. I'm sure some other folks will chime in with their experiences  to 
help out.
