the main conflict in the book the perfect storm
The main conflict is defeating the storm--actually a convergence of three storms onto one geographic location. Yikes!
Other conflicts include the shrimpers' need to make more money by taking one last trip out to sea even though it was the dangerous season.
The shrimper's wives obviously don't want them to go out again as they worry and don't like to be alone.
The shrimp boat owner encourages one last trip as he wants more money as well.
The shrimpers risk losing their jobs if they refuse to make the last trip.
