Plunder and Peril - ship map question

[Combusto]

Hi all - starting to run the module and I'm a little puzzled on something. On the map of the Magpie Princess, on the poop deck, there's some sort of structure other then the wheel. Does anybody know what this is? It doesn't extend beneath that level so it's not a mast, and the anchor wheel is on the other side of the ship? The only thing that comes to mind is that it's where one of the ships launches is kept, and it's vacant in the picture. Any thoughts? Could influence how combat flows in that portion of the ship, whether it has height etc.

You mean the double T structure? Colored like its made of metal? My gues its where they tie up the Spanker or driver sail, so it stays rigid.

The more I look at it the more I think you're right, it does look like a metal securing rod of some sort. Will probably call those squares difficult terrain. Didn't see the equivalent on any other ship maps so it threw me for a bit of a loop.
