As for Aiven himself, he has more pressing matters to attend to.
The universally adopted standard among countries today (actually first started by the Hilus Kingdom) classifies cannon specifications on warships by the weight of the fired cannonballs, with specifications including 9-pound, 12-pound, 18-pound, 24-pound, and 32-pound cannons, assigned based on the size of the warship.
Judging by the specifications of this "Skeleton Tomb," when it was originally in the navy's possession, it should have been equipped with a standard fifty cannons. The two gundecks and the main deck altogether were outfitted with eighteen 24-pound cannons, twenty 12-pound cannons, ten 9-pound cannons, and there were even two small 6-pound cannons mounted on the aft castle.
However, now the ten 9-pound cannons on the main deck have completely disappeared, replaced by ten catapults.
