A Cannon Ram is a piece of equipment that gives the pirate a boost to a specific cannon skill or reduces the reload time for all cannon skills. They can sometimes be found in loot, but are most commonly found in the Cannon DefenseMini Game and Fishing. Famed cannon rams are primarily found in Cannon Defense after level 60.
To use a Cannon Ram, a pirate must place it in their Item Slot of the Weapon Belt. Only the effects of the ram actively in the belt will be applied. The effects are passive, so a pirate does not need to active them.
A Cannon Ram's effects can also apply to the pirate's Broadside attacks. (Ex. Steel Cannon Ram has a Critical Strike ability. A pirate with the ram active while sailing will add the Critical Strike ability to their broadside attacks). This does not apply to other passive skills like Rapid Reload.
