HIGHLANDS - The Coast Guard has recovered the capsized boat of a missing clammer off the Monmouth County shore, but there is still no sign of the missing captain.

Authorities say Edward Broderick was last heard from at around 6 p.m. Saturday, when he told a friend that his vessel was en route to a clamming facility in Highlands.

"It's a dangerous business," says Marina owner Fred Rosiak. "It was rougher than all get-out on Saturday, in retrospect, it was questionable whether they should have worked."

Broderick was reported missing about four hours later when he didn't show up for dinner with friends, and Broderick's submerged vessel was found and identified outside the marina where he originally intended to end his trip.

A rescue boat crew from Coast Guard Station Sandy Hook spent most of Sunday searching for Broderick, along with the state marine police and a helicopter crew from Coast Guard Air Station Atlantic City. The search was suspended at dusk Sunday and resumed shortly after daybreak today.

Water temperatures where the Shrewsbury River meets the Sandy Hook Bay measured about 41 degrees Saturday night. Authorities say it's unclear if someone could survive in water that cold for very long.

Anyone with information about the whereabouts of Broderick is urged to contact Coast Guard Sector New York Command Center at 718-354-4353.
