Steering the Boss Battle Question

[Elizabeth Love Heart]

Last night I actually finished off the soldiers and ships solo but the bridges are where I get hung up.

I went in a second time with my friend and he didnt die so we both got to work on the bridges and we passes the first set but died about half way through the second ones.

Now my question: I been searching everywhere for hints ideas and what to do as the driver of the boat when it comes to the bridges. DO I keep the red in my compus parralel like I do when I sail? I hate the view I have when driving verses shooting cannons. Anyone have pictures or Utubes I can see from a driver vantage point? So I stop the boat and start cannoning myself or does my broadsides do anything? I have passed the boss battle by accident helping another friend. I now am learning to sail it through a friend currently on it. Any ideas and help would be so great!! I searched the forums and Google and find so much about cannoning but nothing about being the driver.
