The crane is identical to that supplied in stage 125, so please refer to that stage for details.  Here's the completed crane.

Fit this crane to the port side of the well deck with a couple of AP screws fitted from underneath.  Like the poop deck cranes, the pins are different sizes so the pedestal will only fit the correct way round.

Fit one of the brackets to the hull, near the middle of the engine room deck head.

Fit the second bracket on the other side of the hull.

This completes the stage and the pack.

Fit the three connectors to the bulkhead with AP screws.

Screw this to the underside of the poop deck.

Fit this assembly to the sunken deck.

It's secured with 4 AP screws fitted to the underside of the sunken deck.

Take the two stairways and fit them to the poop deck.  Only glued the tops of the stairways, allowing the bottom pins to move in the deck.  The decks flex a little so this allows a bit of movement when they are fitted to the hull.

Glue the three vents to the poop deck.  As before, either use superglue or a solvent like Tamiya extra thin, applied from underneath.

Finally, fit the storage boxes (lockers?) on the poop deck.  These are glued with either superglue or a solvent glue.

This completes the stage.

Assembly of the crane is identical to the one supplied in stage 125, so refer to that for details.  Here is the completed crane.

This crane is fitted to the forward starboard side of the poop deck.

The hull plate is used to cover the exposed screw head on the port side of the bow.  I glued this in place with superglue.

This completes the stage.

Take the cable and press it onto the crane upright.

Now secure it with the plastic peg.

Push the crane upright onto the crane motor.  I found this needed a gentle squeeze with a pair of smooth jawed pliers.  Be careful not to mark the parts with the jaws.

Partially insert the long pin into the bottom of the boom.

Fit this to the crane body assembly and push the pin fully home.

Next we partially insert the small pin in the top of the boom.

Slide the hook on the pin.

Now slide the cable and washer on the pin and push the pin home.

Here's a view from the side.

Take the right tie rod and clip it over the pin on the crane body.  The other end is inserted in the small hole just behind the short pin at the boom end.  Repeat with the other tie rod.  I found that the ends needed a small drop of superglue to keep them on place.

Fit the crane to its pedestal and secure with an HP screw from underneath.  The crane should be free to turn on the pedestal.

Fit the crane to the forward port corner of the poop deck.  The pins on the pedestal are different sizes so it only fits one way round.

It's then secured with two AP screws from underneath.

Fit the stairwell access (aka the companion way) to the poop deck.  This should be glued in place.  You can either user superglue, or you can use a solvent glue such as Tamiya Extra Thin applied from underneath after the part is fitted.

This completes the stage.

Stick the self adhesive decking onto the plastic deck.  That's it!  One of the quickest stages in the series!

Screw the plate onto the cross support with 2 AM screws.

Screw the brackets onto the stern the hull.  

Fix the cross support assembly to the brackets with 4 AM screws.

This completes the stage.
