1 vote for enclosing the lazarette. Somehow having a way to ship water directly into the bilge would bother me. The amount of water that can come in through the well when you have the rail buried is surprising. It seems like the drain holes might be a little bit custom. I have a 1" drain that angles aft in the lowest part of the lazarette and is more vertical than those shown here. It drains the slosh from the well without any problem and doesn't take on any water. Baffles are a very good idea. Might be an interesing topic of discussion to find out the various solutions out there.
