ABC News' Matt Gutman reports:
A pair of Florida fishermen who tested the limits of Mother Nature by driving their boat straight through waterspouts call their decision a "calculated risk."
Kevin Johnsen and Aaron Osters were six miles off the shores of the Florida Keys, near Marathon, Fla., catching lobsters when they spotted a rare system with multiple waterspouts, similar to tornadoes on the water.
Johnsen and Osters decided to chase the twisters, and pulled out their camera to capture it all in an 11-minute video Johnsen posted on YouTube last week. They were not injured.
Johnsen can be seen in the video keeping his snorkel on as he, Osters and their dog, Boede, also on board, settle in right beneath a waterspout.
"We're going to batten down the hatches, put on the waterproof [and] then we're going inside," Johnsen says in the video.
By inside, Johnsen means straight into the waterspout, despite the dangers of their boat possibly flipping over amid the swirling winds.
"These are F0 tornadoes," Johnsen said via Skype. "There was no real danger. It was a calculated risk."
The National Oceanic and Atmospheric Administration (NOAA), defines waterspouts as, "tornadoes that form over water, or move from land to water. They have the same characteristics as a land tornado. They are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning."
Johnsen is the owner of Florida Keys Reel Adventures where he works as a charter captain. This incident is the third time Johnsen has gone through a waterspout on a boat, he wrote on YouTube.
