Try a test rander without focal blur nor radiosity.
In that render, use a partly transparent texture for your media container. You 
may discover that those lines are where the media container intersect the sails.

If that's the case, try altering the container's shape or position so that it 
never intersect the sails. If you use a plane, just place it higher so that it's 
placed over the masts.

For your focal blur, try a smaller aperture.
You may also do away with it and use a blured transparency just for the lower 
part. In that kind of scene, focal blur should be minimal, if present at all, 
and only visibly affect the extreme foreground.
