This is just an idea for BB's and other Ships too

Why not Add in a Sight Cone? For Example as you can see in the picture I have Crudely made.

the Red Lines are the gun lines.

The Dark Green Circle is the Ships normal Sight Range.

The light Green Colour is the proposed Sight Cone, Which moves around with the Guns and is barely
wider then the Red Gun Lines and does not help with Spread, this would be kind of like what on a real ship would be the Targeting Veiw Scope (not real name of it of Course).
