Wareham Fire Department and Marion Harbormaster officials rescued five people early Sunday morning who were “cold, but thankfully uninjured” after their boat ran aground near Little Bird Island in Wareham.

Captain Michael Bird of the Wareham Fire Department said the boat hit rocks during low tide. The people on board were fishing and the rainy, foggy weather led to low visibility, which is the reason they ran aground, said Bird.

He noted those onboard suffered “minor bumps and bruises” and declined treatment once back on land.

Bird said all five were standing in about 1-foot of water when officials arrived to make the rescue. Due to the low tide, the boat didn’t sink completely, said Bird.

According to the Wareham Harbormaster Department, Wareham officials were notified at approximately 5:40 a.m. that the boat was taking on water by Wareham Police.

Officials said the reporting party was unsure of the boat's exact location due to poor conditions. In response, Wareham Harbormaster Marine Units 1 and 2 were dispatched along with other agencies from the Buzzards Bay Marine Task Force Unit for the search.

Officials located the boat at 6:30 a.m. in a shallow, rocky area northeast of Little Bird Island. At that time, a Marion Harbormaster vessel arrived and all five on board were removed from the partially sunk boat and taken to Tempest Knob “cold, but thankfully uninjured,” according to a post on the Wareham Harbormaster Department’s Facebook page. All five were wearing lifejackets, officials said.

The Massachusetts Environmental Police were notified and are investigating. The boat was salvaged later during the day during high tide. Salvage efforts were coordinated by TowBoat US Cape Cod/Plymouth.
