The Light

What is a lightship?

A lighthouse that floats, it serves the same function such as:

  • A light to aid navigation at night
  • A horn to warn mariners in fog
  • A radio beacon for longer range identification

Lighting the way
The Overfalls main aid to navigation was a 375 mm dual electric lantern located 57 feet above the water line. Rated at 15,000 candle power, (approximately 1,000 watts), it flashed every 3 seconds from dusk until dawn. On a clear night it could be seen for 12 miles.

The ship also had a dual diaphone fog horn with a range of 5 miles that sounded every 30 seconds in foggy weather.

A radio beacon with a range of 25 miles transmitted the call letters of the ship (NMJF) in Morse code. In foggy weather it was synchronized with the horn and broadcast every 30 seconds.

We've Made It!

This site tells the story of the eleven-year project to save and preserve one of America’s maritime treasures.  It’s a story of tens of thousands of volunteer hours of dirty work bringing one of the few remaining lightships back from the brink of ruin and all of the behind the scenes tasks that made it a reality.  It’s a story of community support that maintained the momentum when any rational person would have thrown in the towel.  And, it’s how this infectious community support spread farther afield raising the $1.2 million necessary to complete the project,
