The seat is just a seat cushion basically that slips onto a couple ridges on either side, so when they come off that whole area is open.
So today I cut out all the wet stuff, here is a photo:
The worst spot was towards the very back, you can see the dark water still sitting there. There was no water sitting between the 2 stringers though. And as I came closer towards the front it got totally dry so I stopped.
The stringers and floor are all coated with fiberglass or some type of gel but it's very hard and not compromised anywhere that I can see so it doesn't look like the water came from underneath. I know it wasn't salt water cause I tasted it last summer as soon as I discovered the wet spot.
It seams like it just somehow got on that area from the top and slowly went thru the carpet...could have been happening for a very long time...I only got the boat last August.
Any ideas how water could get onto just that area?
