Congrats! That looked like a nice, clean boat. That's a 2004 with the two bench seats behind two pilot seats, right?
Exciting times
Couple of notes on bilges/sumps:
First of all, note that the boat has no real "bilge," as in a hidden area beneath the sole. When you are standing in the boat, you are standing on the hull (which is around 1" thick with inner and outer skin, plus core). The exception is the v-berth area which has a liner molding that is slightly above the main hull.
Second, there were changes over the years. Bilge "sumps" (which are just small depressions) were changed, and then in around 2006 the cockpit got a permanent flat sole with air space underneath.
Your 2004 should have the earlier cockpit, where, just like the main cabin, the surface you stand on is the hull. Then..
1) There is likely a shallow depression right on centerline at the transom. This is one of your bilge "sumps." It may or may not have a bilge pump in it (one can be added if you want one and there isn't one). This sump, at least on my boat, did not have the core removed; it was simply made with shallower core (although I have removed the core in that area on my boat to make it a coreless/deeper sump). On my boat it looks like the bilge pump in this sump was added later, possibly by the selling dealer.
2) There is another depression just forward of the cabin/cockpit bulkhead. Not sure when the change was made, but my 2002 has the depression located to starboard, under the galley counter. There is a slit that allows water to go into it from the cockpit. In some year after 2002 (but ending when they made the permanent flat cockpit circa 2006), that sump was moved to the centerline, and will appear as a small step when you enter the cabin. So not sure which of these you will have, but either one typically has a bilge pump in it. This sump on my boat (and I believe others) has the core hollowed out of it, so it is at the level of the outer skin. This sump looks as though it had the bilge pump installed at initial build.
3) The area under the v-berth molding doesn't have any sump and shouldn't have water in it, although some boats have taken on water into this area via either an improperly sealed anchor locker drain (gaps in tabbing at drain is one culprit; tabbing issue at locker bottom is apparently another), or an improperly installed brass stem strip (holes drilled too deeply and penetrated inside of hull). Some of these moldings (including my 2002) have an access hatch (round) under the porta potti.
Welcome aboard and congrats again on your new boat! Not sure if you plan to "remodel" at all, but there are some great photos and ideas in the albums wherein people have made galleys/tables in your style interior (I think C Eagle is one, IIRC).
