The floor gets fillet'd as well...


A few notes here...  I decided to fillet the floor in, which provided a "truss" effect from a boat strength perspective.  In the earlier, pre-floor pics, you'll see the bilge full of stringers.  The floor (1/2" meranti ply) is glued and screwed directly onto the middle keel piece and the stringers.  Then the floor is fillet'd along the edges.  

The boat has a true bilge where the water ends up after rainstorms and wet passengers getting in and out of the boat - the 4 legged kind as well as the 2 legged.  

I installed (3) deck plates in the floor for bilge access to remove dirt and debris.  The deck plates are the "pop up" type, as opposed to the screw-in... the screw type invites dirt, etc. and is hard to turn.  I carry a tiny crow bar to help pop the deck plates out and I stomp on them to put them back in.  I remove the plates after every launch to allow the bilge to dry out.

Several boat builders add foam in their bilges.   I think this is a mistake from three perspectives.  It looks good on paper, i.e. more floatation = greater safety in a spill, however I believe it adds a huge disadvantage in running in bad weather as the water is at a higher center of gravity (above the floatation).  Second, the boat would tend to turtle in the event of a capsize and instead of sitting in a wet boat and waiting for a rescue, one could find himself sitting in the water.  Finally, moisture will migrate to the wood between the floatation and the lack of air will promote rot... and get heavy, etc...
