An Alaska man on a paddleboard escaped a close encounter with a humpback whale, not even getting wet during a tense few seconds caught on camera by friends and family as the giant creature surfaced right in front of him then glided under his board.

"It’s just so massive. You’re puny against this whale," Kevin Williams of Anchorage said Thursday, a week after his adventure with an adult humpback whale in Prince William Sound. Adult females can weigh up to 70,000 pounds and average about 49 feet in length, according to the Alaska Department of Fish and Game. Males are a little smaller.

Williams said anyone who claims they wouldn't be afraid in that situation is crazy.

"If you have a whale that doesn’t know you were there and is that close, that’s not a good situation," he said. One flick of the animal's fin "or anything it does could be the end of my life."

Williams, his son Brian and a couple other friends were paddleboarding or kayaking in the sound just off Whittier, located about 60 miles southeast of Anchorage.

They had seen the whale in the fjord, which is about 2 miles wide. Williams said he was slower than his friends, who were about 200 feet ahead of him.

The whale began to approach his friends, but they were close to the shoreline so he figured the whale would run out of room and reverse course. He thought he was in the safest spot since he was trailing the group.

The whale went underwater for about 45 seconds, longer than he had noticed it dive before.

"And it surfaced right in front of me, coming towards me," Williams said. "Whoa! I love to see whales up close, but I'm on a paddleboard."

As the whale slipped below the water again and turned on its side, he could see the white of its belly slowly gliding underneath, about 3 feet under the surface.

The whale's pectoral fin was sticking a few feet out of the water, and Williams feared the creature might flip over as it swam below him, or he might topple off the board and land on its stomach.

"If I fell down, you know, my feet could have easily been on that whale — tickling that whale or whatever," he said.

To steady himself in case the fin hit, he braced his knees together, kneeled, then lowered himself on all fours.

As the whale passed under him "there was hardly any turbulence, and I didn’t get wet," he said, adding that it’s rare for people to get hurt by whales.

Still, the experience won’t keep Williams off the water. He plans another paddleboarding trip later Thursday.

"I’ll never stop, and this is once in a lifetime," he said.
