Greetings,
I'm trying to get all the major pieces of the superstructure assembled prior to attaching the whole thing to the deck. The next area of concentration is the after most boat deck. There are two boat decks, one forward and one aft, separated by a large support pillar (the large rectangular object to the far right). Here is a view of the actual area. It's kind of cluttered and hard to see. I've studied many photos, cross-checking shapes and relative sizes.

Note that the deck has several extensions of varying size. I've outlined them in heavy white lines in the next photo.

With this in mind, here is the kit part placed loosely in its position. Note that the shape does not match the photos. Now you just know I'm going to remedy that!

Here is my scratch built, corrected piece also placed loosely in position. Note the difference in shape.

Here's a side by side comparison of the kit's boat deck and mine.

While I'm nosing around the boat deck, I've noticed that the davits are incorrectly represented. Note that the real davit is a two piece affair with an upper piece that holds the boat and, when released, slides down the lower support, then tips out over the water. Here is the same original photo with heavy white lines showing the angles and pieces of the real thing. You may want to refer back to the first, unaltered photo to get an unobstructed view of the davits.

Now compare the above davit to the kit part shown below. Again, you know I'll be scratch building a replacement in the future.

By the way, the preceeding discussion applies only to the starboard side. The port side is quite different. In fact, although I haven't given it a final scrutiny, it appears to have no boat deck, at all, even though the kit has both sides being almost identical. On the ship, the boat is a different style from the starboard one and the davits are a different type, being about half the size. Here's a photo of the port side. Compare it to the starboard side in the first photo above.

Work continues. Enjoy.
Regards,
Bob
You are correct. This boat " Командирский Катер" or captains boat it would be called in English does not have a platform under or behind it.It only supported by the divitts. Your reseach is correct and your scratchbuilt boat deck is almost perfect to my drawings. Excellent work.
