Thanks for the illustration, Fred, it may reduce the confusion.
Joel, you are using the term "stringers" correctly. In Fred's illustration you can see 4 stringers - the U shaped stiffeners that run fore and aft to stiffen the hull. On my boat there are 2 stringers as you have described, but they are about 18 inches to 2 feet out from the centerline of the boat, and are not attached to the floors that support the cabin sole and the mast step. (I have hoses routed under the sole in the gap between the port stringer and the end of the floor.) I presume the gap between the stringers and floors is so water trapped in the shallow area forward of the mast step can drain into the bilge when the boat is heeled. In Fred's illustration there are 3 floors, which set crossways in the bilge of the boat and will support the deck. On my 38 I have 3 floors. The mast step is sitting on two of them, and they are glassed to the hull , with the aft floor forming what I think of as the bilge sump. I presume they are glassed into the bilge to reinforce and stabilize the keel stub which also forms the bilge. There is a third floor, or cross member, a couple of feet forward of the companionway steps. It supports a joint in the liner, and is not as substantial as the ones under the mast. It spans the bilge rather than being glassed into it, so that water from aft (stuffing box, etc) can flow forward into the bilge sump. My bulge pump hoses, water heater hoses, bonding wires, and bilge pump power connections run under it. I'm sorry to hear about the water damage to your teak interior. All of my teak is either glassed to the hull with a wide band of tape, or sits on top of the fiberglass hull liner and is glassed or bolted to the liner. The result is that water has to get above the level of the cabin sole before it comes in contact with any teak.

In Joel's case, I wouldn't really call these stringers, although they run longitudinally; and they're not floors. They're the longitudinal support for the mast step.
