2003 Wellcraft Coastal 250 water on cabin floor

Water is leaking in at the seams of the bench seats in my cabin. see attached videos. I have changed the portlight windows, bow hatch, bow light, cleared the anchor rope locker and sealed every nook and crannie I could find. The water is clear and appears to be rain water. No leaks around toilet or vacuum generator. Any suggestions or help would be greatly appreciated.
Thanks Bob

 

An easy way to find deck leaks is to use a hose and have somebody below decks. Start spraying at high pressure and see at which area the water starts coming down.

 

I tried that, but the water is under the 2 front bench seats. There is a channel (made of fiberglass) running under the seats. Somehow the water is getting in there.

 

So no water comes into the boat when you hose it down?

 

Its difficult to explain, the water is under the bench seats on both sides of the boat and remains contained until I bring the boat up on plane and let the bow down abruptly. The force makes the water come out onto the cabin floor through the seams as depicted in the video I attached to the first post. I'll attach some still photos to give you a better perspective. As I said I have I have changed the portlight windows, bow hatch, bow light, cleared the anchor rope locker and sealed every nook and crannie I could find. Still getting water in under the seats. Thanks again any and all suggestions welcomed !!!!

 

Still dealing with this, I thought the leak was at the windshield. I covered most of the bow and the entire windshield with a roof tarp. After a heavy rain water still on cabin floor. See videos on earlier post. Any help would be greatly appreciated

 

Do you have an AC in the boat? It could be the condensate.

 

NO AC
Did you look at the videos? I'm thinking maybe the rub rail????
