Usually we play
Player One " I bore sight you " move to roughly face the enemy ship
Player two - "ok noted " - often a counter , dice or similar is used to remind.

One thing that I love about games that allow for pre-measuring is that it can prevent a lot of the more annoying arguments that crop up in miniatures gaming.
One thing that has proven very helpful comes from the Flames of War rulebook. It recommends that you always declare your intentions (referring to movement only) whenever you move a miniature. We've taken to using this in most of our games. E.g. "I'm stopping 13" from your squadron of Vorchans" or "I'm boresighting your Primus". Everyone agrees when the statement is made (or disagrees and the problem is fixed at once) and the game plays smoothly. No suddenly discovering that you're in range of someone's ion cannons or that you're mysteriously off target for your heavy laser cannon, etc.
It's amazing how gentlemanly a game about blowing each others ships to kingdom come can be when using this method.
