Hi, if anyone is familiar with the forward plug that I think is limited to older boats I'd be grateful for any insight. My boat is a 1987 22' Cruiser. There is water incursion during rain and while I've found a couple small leaks there are still more significant sources. One seems to be the plug right at the threshold to the v berth. It seems that it's most likely a drain for anchor locker water but I don't use the locker. Water still finds its way in. Any ideas where I could be taking in rainwater into that cavity? And how in the heck do you post photo?? What do you do with the "Img" button?
