Source-derived summary

The Greenport Basin and Construction Company, known by various names throughout its history, but most recently named the Greenport Yacht & Shipbuilding Company, is a shipbuilder in Greenport, Suffolk County, New York. It was established in the 19th century by brothers Pliny C. Brigham and Theodore W. Brigham. One local history relates:

Greenport prospered due to the menhaden industry; 64 boats were in service and seven under construction in 1879. By this time, shipbuilding (pleasure craft, cargo vessels, fishing vessels) boomed in Greenport. The Greenport Basin and Construction Company, famous yacht builders, became a large repair and docking facility for menhaden vessels. (Today, the company is known as Greenport Yacht and Shipbuilding.) Menhaden vessels or "bunker boats" were said to have lined the shoreline along Main and Front Streets.

The company built dozens of ships for the United States Navy during World War I and World War II, as well as building yachts for private customers. In 1917 the company became involved in a tax case against the United States, in which it protested the assessment of an "excess profits" tax. The case made its way to the U.S. Supreme Court, where the company finally lost the decision in 1923. In 1970, the company was acquired by Stephen Clarke, and thereafter turned its attention from ship construction to ship maintenance and repairs, and historic preservation of ships.

Editorial analysis

Why this record matters

“Greenport Basin and Construction Company” is worth following because a concise public description often conceals a longer documentary argument. Here, Greenport, Basin and Construction provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Oct 29, 2025. The linked authority identifier is Q16975294. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1879, 1917, 1923 and 1970.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
