Milton, NH (July 16, 2025) – A boat explosion on Townhouse Pond left one person injured Sunday afternoon and prompted a large-scale emergency response from multiple agencies. The incident occurred at approximately 1:18 p.m. on July 13 in the area behind 832 White Mountain Hwy, according to the Strafford County Communications Center.
Milton Fire-Rescue units arrived on the scene within two minutes to find a fully involved boat fire with risks of spreading to nearby vessels and docks. Witnesses told officials that the explosion occurred as the boat’s owner attempted to start the engine while the vessel was tied to a dock. The occupant managed to escape and was transported to a local hospital for treatment of injuries sustained in the blast.
Good Samaritans nearby acted quickly to prevent the fire from spreading to adjacent boats before fire crews brought the blaze under control. Firefighters successfully extinguished the flames by 2:24 p.m. and contained all immediate hazards.
Officials reported that approximately 30 gallons of gasoline were either consumed by the fire or released into Townhouse Pond. The New Hampshire Department of Environmental Services Spill Response team was activated to manage the environmental impact of the fuel spill.
A fire investigation revealed that the explosion was likely caused by the buildup of combustible vapors within the boat’s bilge and engine compartment—an all-too-common risk in gasoline-powered watercraft.
Crews from Frisbie EMS, Rochester Fire Department, Wakefield Fire/Rescue, and New Hampshire Marine Patrol assisted on scene. Cleanup and boat removal operations continued through the afternoon, with all units clearing the scene by 7:06 p.m.
We extend our best wishes to the injured individual and commend the responders and bystanders who worked quickly to prevent a larger disaster.
Boat Explosions and Safety Hazards on New Hampshire Lakes
Sunday’s explosion on Townhouse Pond highlights the hidden dangers that can arise even when boats appear to be operating normally. Fuel vapor accumulation, particularly in older vessels or those lacking proper ventilation, poses a serious threat when ignition sources—like a turning key or spark—are introduced in a confined engine compartment.
In this case, the owner was attempting to start the boat while it was docked, a routine action that instantly turned hazardous due to unseen flammable gases. Boat explosions like this often result in not only physical injuries, but environmental damage and property loss as well.
Boating is a popular activity across New Hampshire’s lakes and ponds, but safety protocols must be followed meticulously to prevent catastrophic outcomes. Pre-start ventilation, regular maintenance of fuel lines and tanks, and routine inspections are vital. Operators are also advised to keep a fire extinguisher onboard and conduct vapor checks before starting their engines—especially after refueling.
This incident also demonstrates the importance of coordinated response efforts. Firefighters, EMS crews, marine patrol officers, and environmental specialists worked in unison to contain the fire, evacuate the injured, and manage the gasoline spill, minimizing wider harm to both people and the ecosystem.
Recovery from such an event involves more than physical healing. Injured boaters may face medical costs, emotional distress, and loss of personal property. In cases involving fuel explosions, detailed investigations are necessary to determine if equipment failure, lack of maintenance, or other factors played a role.
