At midday Monday, there were only a few people out enjoying the ocean at Kaimana Beach, after the weekend sighting of a tiger shark believed to be 10-to-12-feet long.

Lifeguard Ryan Moniz was on duty Sunday afternoon when a group of divers alerted him about their close encounter with a tiger shark in about 20 feet of water just off of the natatorium.

"They did tell me they were being circled because they did have fish on their float. The shark wouldn’t leave them alone," said Moniz.

Troy Maeda and his two friends had been out spearfishing when he said he felt something pull on his float.

"As soon as I felt the pull, I turned around and saw the shark 20 feet behind.  I just unclipped my tag line," said Maeda.

Maeda was able to videotape the shark briefly from a distance.

“It swam within 10 feet of us just a couple feet off of our spears. We were all kind of huddled together, and we were like that for about a half an hour or so," said Maeda.  "From a distance you couldn't see the thrashing but we could see the tail coming out of the water and the float being taken out multiple times."

Maeda also shared snapshots of teeth marks on his spear and photos showing how the shark bent the metal as it was trying to get free, after getting tangled in the dive float.

Maeda and his friends were able to swim to safety, glad to have lost only their fish and car keys.

After the Sunday 3:30 p.m. encounter, lifeguards posted shark warning signs on either side of the natatorium and used bullhorns to warn beachgoers of the threat about a mile down the beach.
