I have had an issue since the first day I bought my boat with leaks on both sides of my 420AC.

With all of the rain in Florida lately, it has gotten worse. The leaks are on both sides and drain into the port cabinet in the laundry room as well as the starboard cabinet in the kitchen.

I have sealed the windows so the leak appears to be coming from somewhere higher.

Where do I need to look now???
 
Bow rail stanchions? Windshield? Hatches? Windlass? Water can migrate in interesting ways. I'd imagine the hatches and windlass are the easiest to identify once you remove them. Windshield and stanchions will be a bit harder.

Having read a lot about wet decks in mid/late 90's Sea Rays I'd wager a bet that the windshield is the most probable source, followed closely by the hatches, with the windlass coming in at a not-so-distant third place with the stanchions following in fourth.

Question - do you have any soft spots in your foredeck?
 
Bow rail stanchions? Windshield? Hatches? Windlass? - All below where the leak is in the boat. No soft spots on the foredeck.

Seems to be coming from up above somewhere

Ahh, I missed the aft cabin part. Sorry about that.
 
I have been fighting a slow weepy out of a drain.

Finally isolated back to the hardtop. Resealed everything on the hardtop.
