A 14-foot great white shark circled a boat carrying a family of Australians, terrified them.
According to video of the event, the encounter lasted over an hour, and the shark even took a few nibbles out of the boat's engine.
In his family's 24-foot boat, a massive predator came up to the surface and attacked his son's fish, he added.
A part of the engine was taken out by Tuckfield, who added, "We were spellbound."
It took around an hour for the "huge magnificent beast" to swim away, according to the account.
