CONTROLS

AG1 - Main Batteries
AG2 - Anti-Air Cannons
AG3 - Torpedo tubes
AG4 - Crane (port)
AG5 - Crane (Starboard)
AG6 - Detach Boats
AG7 - Lay seamines (dont use them unless you launch both of the boats)
AG8 - Gyroscope

HOW TO USE CRANES

Activate the cranes on whichever side you want.
Use VTOL and Trim to grab onto the boat, then activate AG6 to detach and lift the boat, set trim to 50% (up) to carry the boat above the railings and you then rotate the crane 90 degrees on the side to prevent collision.

it should look like that

ABOUT NOTCHES

the notches only help you guide your salvo to the closest possible hits.
you would have to adjust every time you fire and most of the times, you would have to aim a notch higher or below
it aint accurate beyond 7km

WEAPON CONTROL

Main Batteries
after activating AG1, it would be as simple as playing with VTOL and Trim.
the rear turrets would traverse upon activating to face wherever turret 1 looks.

Anti Air
activating AG2 would grant you to control both 20mm and 37mms, however due to my limited abilities, the frontal 37s would be dealing the damage to enemy aircrafts or smaller vessels.
*i advise you to refrain from aiming before the stern as you may hit the bridge

For Torpedoes
simply activate AG3 for torpedoes and use VTOL to aim, though watch out for you might hit your boats
