Yep, the one that is the clearest is the one that counts.
I've also taken the time to begin reviewing the vehocle construction spreadsheets I created for the two earlier versions of SM.
SM1 Tech Law 2nd U.S. ed, 1986 has Jym-bob designing a 1,000 ton spacecraft. The write-up on Tech Law p. 23 shows two turrets each housing a single Mk. 10 laser cannon on the ship view. The deckplan on p. 35 has a space marked Gun Turret and on either side something that might be an access ladder or maybe gunnery controls. There are two designated fire control stations, which I'm guessing are for the M/A torpedo launcher.
If the two symbols are gunnery couches then the example missed the need for a HUD for each turret.
Other than that everything seems okay.
