400: Fresh water leak

[feebs]

Hi all,

I have a fresh water leak - only after it rains - in aft portion of my starboard hull, forward of engine bay.

After a night of heavy rain, I end up with about half a bucket of water in my bilge.

A line of paper towel in centre section of hull doesn't show ingress point, so I installed a temporary "Dam" ( clear plastic siliconed just in front of starboard engine battery). After next rain event, water aft of Dam was higher than in front, so believe rain is entering aft of my dam.

Seeking help in finding ingress point, which is a little difficult around aft bed area, as bed structure precludes laying a line of paper towel to help locate it. Walls are dry. Water heater is also dry.

Any ideas would be greatly appreciated.

Hi Brett
I had some leaking around this area which turned out to be a very small hole in plastic pipe fitting it was hard to find.
If it is from rain as you say, I would check the base stanchion posts, rigging fittings in the deck, we have the aft block for the screacher sheet in that area, gas bottle storage tub, any chance you could send some photos of that area outside would give us a better idea of what else can cause the leak.
Regards
Nick

when washing boat, wash areas selectively. Water traces will be visible quickly, if you got so much water when rain.
