ABSTRACT:
A pneumatically activated signal flag is used in combination with a first watercraft to provide a visual warning to other watercraft operators of various events which may be occurring around the first watercraft. For example, the signal flag may indicate that a swimmer is in the water adjacent to the watercraft. The signal flag is raised or lowered by activation of a pneumatic activating ram by an operator within the water craft.
