Construction: Week 20 - Concurrent Carpentry

Here are today's "Friday" photos.  My first impression was that not much was going on.  I changed my mind after chatting with Mike Schlichtig.  The changes are subtle and in some cases you will have to look hard but it is clear that progress is being made.

Now we have photos of concurrent work going on in the carpentry shop.  The two below show the platform for king size berth in the master stateroom and the queen sized berth in the VIP (aka V-berth).

Work is also progressing in the engine room and in the accommodations.

Let's start with the engine room.  For comparison I've included a photo from last week to allow you to better see the changes.


Week 19. Engine room photo showing insulation on the floor just aft of the forward bulkhead

Week 20. Worker fabricating the framework for fuel tank insulation

The photo shows a worker fabricating the frame that will be used hold the sound proofing insulation structure around the fuel tanks.  This is the same multiple layer insulation structure used on the bulkheads and ceiling.

Also note the green wire running from the inspection port (round circle) on the starboard tank and along the frame adjacent to the forward bulkhead.  You can also see wire running from the port tank.  That "green wire" is bonding cable that will ultimately connect the tanks and all other metallic components to the "Central Bonding Strip" whose role is to prevent electrolysis.

Explanatory Note: Electrolysis is caused when an external current, called a stray current finds a path between two metals in the presence of an electrolyte (water and moisture). The two metals may be of exactly the same type or different types.  If the stray current is sufficient to overcome the natural galvanic current then the more noble metal may well become the anode and is thus destroyed. The rate of electrolysis attack is dependent on the amount of current present. A stray current caused by a short circuit can ‘eat’ metal components away in a very short period of time.

Now we move to the accommodations.

The photo below shows the master stateroom.  Here's how to understand the photo.  The partition in the upper left delineates the one of the two hanging lockers.  At the upper right is the edge of the fiberglass shower. In the center of the photo under the sub-floor is the 300 gallon water tank.


Week 20.  Master stateroom looking to starboard

  with plumbing visible

Notice the blue hose toward the back of the tank.  That is the cold water PVC piping running to the shower.  That hose connects to a water manifold (distribution point), which connects to a fresh water pump and then to the water tank itself.

Clicking on the photo will cause it to expand so you can see more detail. To the left of the water tank you can see framing along its side and immediately below it a red hot water hose.  There is also bonding wire that will connect the aluminum water tank to the "Central Bonding Strip."  The hot water hose also connects to the water manifold (distribution point).  Before that it connects to the 20 gallon hot water heater located under the floor in the next compartment.

Immediately adjacent to the hanging locker bulkhead you can see a wide black hose.  That appears to be the drain hose that will eventually be connected to the commode in the master head.  That hose goes directly to the boat's 100 gallon black water holding tank.

The photo below is the master stateroom looking to port.  Expanding this photo will allow you to see wiring hangers that run along the frame on the port side of the water tank.

Week 20.  Master stateroom looking to port

The sub flooring will eventually be covered with marine plywood.  On top of that will be a thin rubber mat to hold the carpet in place.  Unlike a home, the carpet is not nailed to the floor.  It must be removable to gain access to numerous hatches which provide access to equipment (e.g., grey water pumps) and the ability to check the bilges.

Notice the red toy car in the photo.  My best guess is that it is a radio owned by a worker.  Otherwise, I have absolutely no idea why it is there.
