The real point of interest on this tour is the third picture.
THis is the aft most bilge access (under the sink).
The upward slope (to the left in the picture) is going aft, it tapers down forward to the bilge pump (forward, or to the right in the picture).
THere is no 'deep sump' on Faith, and the more I look at the glass down there, the less I believe there may have ever been one.
