For over one-hundred and fifty years, vessels worldwide have used flags to communicate important messages regarding safety and other related matters to passing ships. The “O” flag is part of the International Code of Signals used for Man-Overboard (MOB) occurrences. Vessels may communicate a MOB situation using the phonetic pronunciation of “O” by calling out “Oscar” so the receiver clearly understands the speaker is communicating “O”. Since Oscar has become synonymous with MOB, it only made sense for our water rescue training dummy to be called “Oscar”. However, you can call our product anything you like, as long as you respect the powerful tool that it is.
