FERRY MADONNA CONSTRUCTION PROGRESS 8.0



Bow-on shot taken Monday, December 1st, by Rich Ellefson 

Detroit Harbor, Washington Island -

Heavy rain, sleet and high winds from the ENE on Wednesday did little to slow construction on the Madonna, nor did the blizzard that followed, Saturday, Nov. 30 into late Sunday, Dec. 1 that dropped between 12 and 15 inches of wet snow on much of Door County.  Shown above in one of several photos taken by Rich Ellefson on his weekly visit to the Fincantieri Bay Shipbuilding facility, all bow plates are now tacked in place, awaiting welds to fill gaps and connect the plating.

A view of the Madonna engine room (in the still-inverted position) shows scale of worker in the soon-to-be machinery space.  He stands on what appears to be the through-bulkhead section of the port main engine exhaust pipe.  This would be the port side of the engine room looking aft, if I have it right.
Overhead photo shows substantial car deck overhang, port and starboard,
with scaffolding set up that allows welders to begin stitching
hull plating together.  

If it seems confusing enough interpreting such a photo, real credit goes
to shipyard work force who construct the entire hull in the upside-down
orientation, with close tolerances using pre-cut plates.  Exhaust piping
beneath worker shown above runs through aft engine room buklhead and
the void space below car deck, eventually exiting the
shell plating just forward of the transom.

As I look at the overhead view (2nd photo from top, above), I marvel at the number of enclosed spaces there will be when the car deck's bottom plating is installed. That will require a lot of interior welding in very close quarters. And then priming/painting. And somehow access fur future inspections and servicing must be provided. I'm having a hard time picturing the details but I'm sure the naval architect has all the provisions covered very well. Thanks again, Dick, for these regular fascinating updates!
