After a lot of blood, sweat and tears, the decks are all attached.  The instructions show to attach all the little vents and other doodads  
before mounting the decks.  Trust me, this is a bad idea.  Because you will be doing a lot of pushing, pulling, and clamping.  Leave all the little guys off till the very end.  I would have to anyway because of the wood deck going on first, but even without the deck, skip those steps until the end.
Here's some of that clamping action...
 
 Another issue is that there are fairly large gaps between deck and hull.  Lots of putty is needed.  It is at this point where I  
highly recommend a wood deck.  Not just for the masking and painting times savings, but the fact that you don't have to worry about scraping off any planking detail when you smooth out the putty.  In this way I put the putty on and when I sand it down tomorrow, there's no worry about messing up deck planking detail because the wood will cover it anyway.


 
 By the way, notice how the flight deck is completely smooth.  It used to look like this...
 
 But the entire thing will be replaced with PE, so all the molded on detail gets removed.  Speaking of PE, I'm beginning to notice a very disturbing trend regarding the PE instructions.  Often they don't show what the finished part is supposed to look like.  You will make good use of your reference material with this kit (the catapult immediately comes to mind- it looks great, but without references you'll scratch your head).
The PE instructions are very vague- for example they tell you which PE boat cradles go on the main deck, but NOT the upper deck (where there are the most).  So for that, make sure you measure each plastic cradle and make a note, so you'll know which PE replacements go where.
Finally, we have a big problem with the forward deck area bowing, causing the forward superstructure to sit askew like so (I hollowed out the portholes):
 
 Ouch!  
 
 My remedy for this will be to cut out a sizable chunk of the "dead space" that goes under the superstructure so I can better level out the bowing.  As it is now, there is too much surface tension- if I really force the structure down, the deck flattens out, but that won't work in the long run, so I'll have to relieve the pressure.
Stay tuned...
