A New Hampshire teen was seen on video leaping from a jet ski to stop a runaway boat after its sailing instructor was knocked overboard last week.

Brady Procon, 17, jumped into action after his father, Jeremy, told him that an unmanned boat was speeding in circles in Smith’s Cove on Lake Winnipesaukee.

“I was sitting on the porch and my dad yelled that there was an out-of-control boat in the wake zone,” the teen told WMUR-TV.

Procon told the outlet that the operator of the boat, which is part of a local sailing association, is a sailing instructor who was teaching kids how to sail at the time.

Video captured Procon jumping onto the speeding boat and bringing the vessel to a stop.

“I’m a little, I’m realizing what I did, a little bit scared, but it was fun, I’d do it again,” Procon told the outlet.

There were no immediate reports of any injuries related to the incident.

Lake Winnipesaukee, the largest lake in New Hampshire, is located in the foothills of the White Mountains in Belknap and Carrol Counties.
