STONINGTON, Conn. — The Stonington Harbor Management Commission is opposing a U.S. Coast Guard proposal to make a foghorn on the Stonington Harbor Outer Breakwater radio-activated rather than automatically sounding around the clock.

The Day of New London reports that boaters complained that changing how the fog signal is activated would be unsafe for small boats that don’t carry the radio systems needed to activate the signal.

The Coast Guard is converting Maine and New Hampshire foghorns that are automated to activate in the presence of fog. It says newer technology activated by mariners via marine radios is safer and more cost effective.

Stonington resident Tom Castle was alone in his opposition to the foghorn. He says it makes a lot of noise and nine months of the year no one is present.
