I single out TU simply because having been in NOLA he's probably familiar with maritime stuff.
I got into a disagreement with an instructor a week or so back. We were discussing USL&H and Jones Act requirements, and she gave a definition of "navigable water" that I disagreed with.
Her definition: "Any body of water connected to the Pacific or Atlantic Oceans."
My definition: "Any body of water that is either subject to tidal activity or can be used for the transport of interstate commerce."
A quick Googling shows that I'm right-however, are there some common law rulings I don't know about that affect this that would make her correct? She's somewhat an expert on Work Comp and related issues, so I would usually take her word for it on USL&H and Jones Act stuff.
