The lamp was a catadioptric apparatus of the fourth order, commonly called the Fresnel light. The light was first exhibited December 10, 1856. In 1900 a fixed red lens-lantern beacon light was installed at the extremity of Brant Point, 600 feet from the tower, it having been found necessary to move the light outward, owing to changes in the channel leading into the harbor of Nantucket. This was the ninth light to be located on the Brant Point site. In 1901 a new tower, the tenth light and seventh tower, was built at the extremity of the point, and the light exhibited there for the first time on January 31, 1901. This is still in use as a white cylindrical (wooden) tower, with foot bridge to shore on which is a 1300 candlepower, fourth-order electric light, fixed red, 26 feet above the water, visible 10 miles. This is the lowest lighthouse in New England. It is located on the west side of the entrance to Nantucket Harbor. A fog bell completes the equipment at this station. A long-standing dispute begun in 1887, over the boundaries of the land constituting the lighthouse site, which belonged to the United States, was finally settled in 1901 when five lots, embracing 5.9 acres, on which three summer dwellings and part of a hotel were located, were sold, as no longer needed for lighthouse purposes and the proceeds paid into the Treasury. (5) _MASSACHUSETTS_ BUZZARDS BAY LIGHTHOUSE In 1960 the Coast Guard announced that it was replacing certain lightships with fixed offshore structures. The structures they noted, would provide more efficient optics and would provide greater luminous range than was possible with lightships. The first lightship to be replaced was the Buzzards Bay Lightship located in Buzzards Bay approximately five miles south of Gooseberry Neck, Mass., in 61 feet of water. The station was commissioned on November 1, 1961. The underwater portion of the structure is a framework consisting of four 33 inch steel pipe members cross braced with 16 inch and 18 inch diameter steel pipe horizontally and diagonally. Through each of the 33 inch main pipe members, 30 inch cylindrical steel piles were driven and seated to bed rock at a depth of 268 feet below mean low water. A portion of the piles is filled with concrete. The platform above water rises 66 feet above mean low water. The platform is two decks high, the lower deck housing fuel and water tanks and the upper deck consisting of quarters for the five Coast Guardsmen who man the station. The structure is equipped with a helicopter landing deck. The light at the station is 101 feet above water. A light of 5,000,000 candlepower is shown during periods of low visibility while a 400,000 candlepower light is normally in operation. The light can be seen for 16 miles. The station is also equipped with a radiobeacon and a fog horn. The piles are floodlighted from sunset to sunrise.
