I think OE Acorazado makes sense with its flavor text. It’s a centuries old warship that was found rotting away in drydock and they just slapped some harpoons on it and sent it away. It’s supposed to be underpowered.
I want to know what the hell they were thinking with ships like Hannah, Majestic, and La Colibri. (The “ships within S get +1 to their cannon rolls” ships that are all 15+ points)
