What's Under the Teak Deck? (Tuggers Vol.62)

The same black polysulfide that is used to seam between the deck boards was also used underneath them.  The following sequence of pictures was taken after the teak deck and the underlying polysulfide was removed.

From Trev Croteau, Hjortie #33:

The sub structure of the deck is quite interesting. Note the photos below. Especially the last photo. A hatch was cut to install the steering quadrant?  Quite a few "plugs" in the deck as you can see in the photos. I found all my leaks!
