So we saw the photo(s) of Garrett McNnamara and his tow partner Keali’i Mamala surfing giant waves today at Praia do Norte in Nazaré, Portugal. Some claim these waves may have been 100-feet tall. But who knows? All we know is that a video has arrived, in the form of this trailer, and we will indeed watch whatever full-length video arrives in the near future. Because, wow, those are big waves.
