Hi All, I am an avid reader of the Monty e-mails but a very infrequent participant. I am what one may call a casual sailer with little knowledge of manufacture. As I was removing my porta-potty for cleaning (always an enjoyable experience) I noticed that the floor in the cabin (roughly 3" or so from the v-berth and back toward the companionway hatch about 4 inches or so, about a 4" circle right in the middle of the boat) was a bit spongy. It would move down with the pressure of my foot. I felt like, even though my gentle pressure would not break through at this time, that perhaps the time was coming when it would. There is a little inspection hatch right there at the bottom of the v-berth and when i opened it it seemed damp inside but not wet. I took her out last about 2 weeks ago. Questions arise such as 1) is there a marine plywood subfloor under the fiberglass? 2) is the water getting in from the centerboard well? 3) could the same sponginess be found on the other side (the hull)? 4) what is the expense of a repair? 5) is one needed now or can one simply wait until it gets worse? or 6) my favorite one... is this nothing to worry about and should i just keep sailing?
