Fire Department Marine units were in the “right place at the right time” to help a Goffstown man after he collided with another jet ski on Cobbetts Pond in Windham on July 5, according to Fire Chief Thomas McPherson.

Two firefighters and a deputy chief had been deployed on the pond in the department’s 14-foot boat with a third firefighter on a jet ski in advance of the town’s annual fireworks display when reports began coming in around 8 p.m. that two watercrafts had collided and left multiple victims in the water, McPherson said. Originally scheduled for Friday, July 3, the town’s Fourth of July celebration was postponed until July 5.

“Every year for the fireworks we have a detail on the water to go around and promote boater safety during the fireworks,” McPherson said. “Certainly in this instance it’s proven to be an asset to have that unit. We were able to be in the right place at the right time to immediately render medical assistance.”

Firefighters already on the pond responded to the scene and found 23-year-old Jeffrey LeMay of Goffstown in the water without visible injuries. 19-year-old Jonathan LeMay, also of Goffstown, had already been pulled up into a waiting pontoon boat, according to officials.

McPherson said the younger LeMay was semiconscious and vomiting, suffering from a severe laceration to his head.

Though emergency responders began immediately performing first aid, officials had LeMay transported by ambulance to nearby Griffin Park where he was flown to the Brigham and Womens Hospital in Boston.

Jeffrey LeMay was evaluated, but refused treatment at the scene, according to officials. Authorities have not confirmed whether the two men are related.

According to Sgt. Joshua Dirth of the New Hampshire Marine Patrol, LeMay is in stable condition. The accident remains under investigation and authorities have not yet ruled out alcohol or drugs as a factor in the collision, he said.

The collision is the first accident involving a personal watercraft on record in the state this year.

McPherson said this is the second time the department’s marine unit has responded to an emergency on the pond.

About two years ago a firefighter on the department’s personal watercraft was able to retrieve a young girl struggle in the water and bring her to shore, he said.

The jet ski is kept docked on the town beach during the summer months. According to McPherson, both the boat – fully equipped with medical supplies – and the personal watercraft are inspected on a weekly basis and tested on the water once a month.
