360 View from Deckgun

[BowfinSS287]

hello

I found out that on the S-Class boats if you press F10 to get to
deckgun (i use SH3 keys) then press F9,you get a 360 view from
the deckgun position. I guess this happens because there is no
conning tower location on S-Class boats. Now i need a real pro
to make this work on the other boats,is there a way of making a
area that does not exist to get this to happen on all boats

Happy Hunting
