Do any of the charter companies do online education and testing? Navigare's screening (or lack thereof) of captains has been discussed, but it seems that online training and a test could improve outcomes. Captains might better absorb information in advance than after a long day's travel while they're worrying about their booze delivery.

Subjects like color coding of flags and bouys would lend themselves to online education, but there are probably many topics which could be included.
