Leak into aft cabin

Check out the hull to deck joint/connection and the rub rail that usually covers that joint. Water gets in through the screws for the rub rail or behind the rub rail through the screws holding the hull / deck together. This tends to be a point area of leaks on some boats.
Second check out any near by windows or port holes for leaks , along with weep holes for window drains.... Boats are such fun!

Hi, when you say you have re-caulked them, did you remove them and rebed them or caulk around the bases ?

I have a 2004 466 carver motor yacht. I have own it for the last 6 years, recently I have been battling a leak in my aft cabin over the bed. it seems to accumulate in the ceiling panels and than overflows down on to the bed, mostly on the starboard side. anyone have any idea where this can be coming from. I have re calked the radar arch and that seemed to slow it down for a while, now I am running out of things to calk. Any help would be appreciated

Don't count on the leak being on the starboard side. If your boat lists even slightly to that side, maybe caused by the weight of a gen or such, the leak could travel from anywhere. pull down ceiling panels and see if water marks can lead you to the source. Failing that flood likely sources with a hose until you recreate the leak.
