I don't recall where I the post is, but I remember someone saying 19'6" as a max height and 6' as a max draft. What are the consequences for violating this? Four or five open ocean runs of 40 miles or less? Or does it make the loop almost impossible?
May have been answered, but that 19'6" is absolute - if you can't get under that, the Great Loop becomes the Great U-turn. Its a fixed bridge west of Chicago. (actually was once a movable bridge, but became inoperable many years ago and IL is too broke to repair it)
