I have looked at the photos. The construction of your 35 MKIII below the cabin sole is substantially different from the 35 MKII. The MKIII has many more athwart ship sections than the MKII and it appears as though the sole is fastened to those sections and that those sections may be hollow or cored. On the MKII there are fewer athwart ship sections, in fact, there is one for each keel bolt aft of the mast and I believe one at the mast and the keel bolts (6 in total, 2 at the mast and 4 aft of that) come up through the centers of these sections, which are about 6-8 inches wide and about 1.5 inches solid thickness of glass matt and resin that appear to have been hand laid up and which extend up and outward on either side of the bilge fastened to the hull on either side of the hull. The cabin liner, including the integral fiberglass sole seems to have been dropped in and these solid glass matt / resin impregnated bilge sections are well below the fiberglass sole. The teak and holy sole is glued to the fiberglass sole which is not in contact with these athwart ship strength members where one can see from the bilge opening but may be in contact up under the settees. I like the MKII design, it is likely heavier but it is also very strong and provides for very solid attachment of the lead keel. There are no limber holes and I don't believe they are necessary but the water that does collect between these athwart ship members must be removed regularly with a sponge to achieve a dry bilge, since that water is blocked from flowing fore or aft to the bilge pump by the thickness of these sections at the bottom of the bilge.

Its at http://www.facebook.com/Theoffice35. Scroll down and look for the dirty bilge. The mast is at the top of the photo.

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.
