Lifting the forward section of the deckhouse and lowering it into place. This will be aligned  with "alignment clips" that are welded to the deck and funnel the part exactly in place

Ship fitters are cutting the edge of the deck to accommodate the shape of the deck house. Later the bottom 2 inches are trimmed off the deck house edge to ensure a form fit where the deck house meets the deck.

Lifting the bow section and rotating it for installation. The two mobile cranes are brought in and positioned.

Mobile cranes work with the overhead cranes to lift and rotate the bow section into its installation attitude. It is then aligned with the frames and shell plate on the boat, pulled in tight with come-a-longs and turnbuckles and then tack welded. Each shell seam is then cut by hand  to fit with the plates they will be attached to on the boat.

Now that the bow is attached it is welded to the boat. Here welders weld the inside seams and back gouge and weld the outside seams. A welder can be seen gouging or "air arcing" sometimes called back scarffing the side shell seam. This allows the penetration of the weld to be 100%. This makes up the final section and the hull is now complete.

With a coat of paint on the bottom, the boat is looking much better. Here the rubber fenders are installed and small steel tabs are welded onto the channel that has been attached to the sides holding the rubber in place. The push rubber is then installed in two sections, these are the rubber tires or pieces of tires held together with one inch  all thread shafts that the boat uses for pushing avoiding damaging the bow.
