The Fascinating History

Thatcher Island, located off the coast of Rockport, Massachusetts, boasts a rich history that is reflected even in its name. The story behind the island's name is an intriguing tale of exploration, survival, and honor.

The island owes its name to English explorer, sailor, and cartographer, Anthony Thacher. In the early 17th century, as European settlers were beginning to establish their presence in the New World, Thacher embarked on a perilous expedition. Sailing from England, Thacher and his crew found themselves navigating the treacherous waters of the Massachusetts coast.

Sailing from England, Thacher and his crew found themselves navigating the treacherous waters of the Massachusetts coast.

On a fateful stormy night in 1635, Thacher's vessel, the Watch and Wait, was caught in a violent tempest. Blinded by the raging winds and heavy rain, Thacher's ship was mercilessly driven towards the rocky shores. Sadly the Watch and Wait met its fate on the rocky shores. Thacher and his wife survived, his four children from a previous marriage perished along with Thacher’s cousin, his wife and six children. In total 21 people died. The court awarded Anthony Thacher the island at the head of Cape Ann to compensate him for his losses, he originally dubbed the island “Thacher’s Woe”.

Today, Thacher Island continues to draw adventurers and history enthusiasts. Its picturesque twin lighthouses, originally constructed in 1771, stands as a silent sentinel, guiding ships safely through the dark of night. The lighthouses symbolize the importance of vigilance, resilience, and the beacon of hope amidst the storm.

The Role of Twin Lighthouses

Twin lighthouses, a sight not often found along coastlines, play a crucial role in aiding mariners to navigate safely through treacherous waters. These beacons of light not only serve as powerful visual signals but also work in tandem to establish a range and bearing, enabling sailors to determine which side of an obstacle they are on. One of the most significant functions of twin lighthouses is to establish a range. A range is a line of sight created by aligning two or more landmarks, typically lighthouses, that helps ships maintain a safe course. By ensuring the ship remains within the range, mariners can navigate without the fear of straying into dangerous areas. When twin lighthouses are positioned carefully along the coast, their distinct characteristics, such as height, color, or flash patterns, make them easily distinguishable to sailors and aid in establishing a clear range.

Apart from range, twin lighthouses also provide an essential navigational aid called bearing determination. A bearing is the direction in which an object or point is located concerning a frame of reference, usually true north. The towers of Thacher Island were erected on a perfect north/south axis, which enabled sailors to line up the lights to determine true north. Twin lighthouses, when visually identified by a mariner, allow for the determination of a bearing that indicates which side of a particular object, such as a rocky shore or an isolated reef, the ship is positioned on. By comparing the relative bearings of the two lighthouses, mariners can accurately ascertain their location in relation to the obstacle. This information is crucial for maintaining a safe distance and plotting a suitable course.

In summary, twin lighthouses possess a remarkable ability to aid navigation by establishing a range and bearing, which ultimately determines which side of an object a ship is on. Their visual characteristics and strategic placement along coastlines are key to their effectiveness. By relying on these invaluable aids, mariners can safely navigate through perilous waters and avoid potential dangers.
