“My lord admiral! Look, the Ottomans appear to be sending us some sort of signal! What can you see through your spyglass?”

Interestingly enough, crossbows have much flatter trajectories than bows, even when firing at similar ranges. The arrow will have a greater ‘arc’ that needs to be adjusted for, while a crossbow will be more ‘point-and-shoot’. To a degree, at least! And at a cost - a crossbow bolt usually has a lower maximum range than an arrow loosed from a bow!
