Yes, once sealed, it appeared only to accumulate in the first bilge compartment right behind the mast.
I have occasionally gotten a little in the 'aft bilge' area in front of the engine (not the engine pan, but right in front of the seacock for the water intake). I"m not sure where it comes from, sounds like the lazarette is a common entry point after reading this thread. It seems to be intermittent so I haven't worried about it too much.
My ice box drain is routed to a small manual pump that is located under the sink, which T-s into the sink drain. So I know mine isn't coming from the icebox.
