The dangers of rogue waves

A rogue wave is defined as being at least 2.2 times as high as the average waves which have come before. They are described as coming out of nowhere and their consequences can be deadly. 
In her documentary, The Wave, Joan Webber chronicles swimmers struck by these potentially deadly maritime phenomena. Though rogue waves themselves are not infrequent, it's considered rare that a person is hit by one. But rare .… is not never.
We also bring you another story about the sea titled, When I Came to Canada. It’s Hon Lou’s harrowing account of fleeing Vietnam by boat as a child following the end of the Vietnam war. 
The Wave was produced by Joan Webber with help from Liz Hoath and originally aired on The Current. 
When I Came to Canada first aired on Living Out Loud and was produced by Steve Wadhams.
