A boating trip off the coast of New Hampshire turned into a heart-stopping ordeal when a whale breached beside a small vessel, flipping it over and sending two people into the water.

The dramatic moment, caught on video by nearby witnesses, shows the massive whale crashing back into the ocean and the boat toppling. Within moments, nearby vessels rushed in, pulling the two passengers to safety. Thankfully, no one was seriously injured.

Marine officials remind boaters to keep a safe distance from whales, whose sheer size and strength can make close encounters dangerous. The viral video has since fueled online discussions about both the beauty—and unpredictability—of sharing the ocean with such powerful creatures.
