Seaman Status in Wilander's Wake

In the Wilander Court's limited wake, three areas of seaman status law remain unsettled and continue to generate confusion and conflicting decisions in the lower courts. It is unclear what effect Wilander will have on the issues it failed to resolve. First, should seaman status extend to traditional seamen, such as pilots and divers, who spend most of their time working on numerous vessels, but have no permanent assignment to a vessel? Second, does Robison's “substantial work” alternative to “permanent assignment” survive Wilander's “employment-related connection to a vessel” requirement? Third, what is the test for determining whether a floatable structure is a Jones Act vessel?
