Sure, let me entertain you.
Utilizing the calculations from
@Ned_Reddavis ' post above, we can figure that 77% of your broadsides sit with a single explosive, and a volley of anywhere from 8-11 Round Shot. Sure, on its own, a single explosive is fairly irrelevant facing the consistency of Fury and Thunderbolt, but lets take in for a second some cannon ram calculations.
Steel Cannon Ram, AKA Round Shot Crit-Ram utilizes a +3 Boost to the typically maxed out +5 Round Shot, boosting the damage by an additional (I believe 12%). Atop of this, there is about a 22.7% chance that each of these individual round shot will leave the broadside as a critical Round Shot, dealing anywhere from 1.5x - 2.0x the damage of a standard shot.
While the same could be said for Skull and Bones, the potential power of a single shot as opposed to 4, 5, or even more of the competitors' ammunition means that at least 40% of the broadside will be utilized purely for the modification such as Fury or Thunderbolt, whereas Copperhead utilizes a
SINGLE shot in a broadside to deal the same damage potential.
You can't just look at what numbers mean on paper and think that a change to one mechanic completely drops the potential of something. Sure, Copperhead can't bombard and sink an enemy hunter in ONE broadside anymore, but you are very likely to consistently do it in two, and that's with a relative consistency that makes it invariably lethal against standard warships and below.
