Why Assassin's Creed's Jackdaw is too heavily armed to be a brig

How accurate is Jackdaw in Assassin's Creed IV as a brig?

The panel considers its forty-six-gun battery much closer to a large frigate or fourth rate than to the eighteen-gun brig used for comparison.

Jackdaw's advertised forty-six broadside guns cause the panel to question the game's brig label. The comparison uses an eighteen-gun brig, with roughly nine guns per side, against Jackdaw's twenty-three per side. On armament, the panel places the fictional ship closer to a large frigate or fourth rate. This is a criticism of the game's combination of label and battery, rather than a measured reconstruction of the ship. A later clarification repeats that eighteen means the total on both sides, avoiding a mistaken comparison of eighteen with twenty-three.
