I'm a new Moomba owner and I suspect my boat has water in the same area as mentioned. Seems like an obvious place for water to gather considering the drop-keel. I've also wondered what good the drain plug in the back does considering it is nearly the highest point in the bilge when its sitting on the trailer on level ground.

At any rate, I'm not overly worried and I'm happy to do the deck plate mod and suck the water out. I read through this whole discussion (ok, skimmed) and don't recall seeing any mention of installing a drain plug at the bottom of the drop keel. Maybe on one side the of the keel an inch or so up, just to let the majority of the water out.

I'm in no hurry to drill holes in the bottom of my boat, but I wonder if anyone has taken this approach? I've seen a mid-ship drain plug installed between the tracking fins...
