Cannon Glitch

The cannon gltich is the glitch in which when you fire into an oponents port or starboard, the damage goes to the much weaker bow. This allows you to sink an enemy much more easily than if you were to be hitting their port or starboard.

Why Does This Happen?
I imagine something is wrong with the hitboxes for the ships.

How to do it
Although there is no definite way that will allow you to get it right every time, there is something you can do to have a better shot at it. You must pull alongside the ship you are targeting, and make sure that as many cannons as possible will hit her. You must also make sure that your forward cannons will hit her bow. That will give you the best chance of success with this glitch.
