Cannon (facility)

A cannon is a boat facility that can be built and is involved in boat combat. Cannons have a 7 tick attack speed and can only fire cannonballs up to their own tier (e.g. an iron cannon can fire bronze and iron cannonballs, but not steel cannonballs). Cannons must be positioned on the same side of the boat as the target to attack. It is possible to attack with both cannons simultaneously by building both cannons on the same side of the boat, or if the target is positioned directly in front of or behind the boat with a cannon on either side.

When a player operates a cannon, both Sailing and Ranged experience is gained. When a crewmate operates a cannon, only Sailing experience is gained.

A visible Sailing boost can be used to build a higher tier cannon. Visible boosts for Sailing and Ranged levels can also be used to fire from cannons.

While an anchor is dropped and either the player or a crewmate is manning the helm, the boat can be turned on the spot while another character mans a cannon to allow the ship to quickly face new targets. Cannonballs can be recovered with the use of a ballistic attractor, which automatically recovers 60% of cannonballs fired.

When a player mounts a cannon, the damage of the cannonballs are affected by the type of cannon used, the type of cannonballs used, Ranged-boosting prayers such as Rigour, and the player's visible Ranged level.

Preferred cannonballs can be set by using them on a cannon to avoid automatically using the highest tier you are carrying.

Due to an update, the information in this article may be out-of-date. Reason: The crewmate formula doesn't account for the player's Sailing level anymore. The exact formula is currently unknown. You can help improve it by updating the information.

• Cannons benefit from the player’s ranged accuracy and strength bonuses. Ranged strength bonuses from the weapon, shield, and ammunition slots are excluded from this calculation.
  • Take precaution with items where the applied strength bonus is conditional, eg. a charged Dizana's Quiver.
