A boat overturned off Sea Girt Saturday morning, submerging two beach replenishment surveyors in the frigid ocean when air temperatures were six degrees.

Both crew members were in the water for about ten minutes and were suffering from hypothermia, according to the Asbury Park Press.

Authorities said two waves struck the boat, the first hitting its stern and the second causing the vessel to overturn and take on water before 9 a.m.  One of the passengers was thrown into the water while the driver was trapped in the cabin.

One of the victims reportedly was driven by private vehicle to Jersey Shore University Medical Center in Neptune for treatment. The other was taken to a private home.

A beach replenishment worker in the area drove her equipment into the surf to pull the boat out of the water, police said.

The incident did not result in any fuel or oil leaking from the capsized boat, according to authorities.
