Problem: Information: - A schooner / skunr / is a type of sailing vessel with fore - and - aft sails on two or more masts , the foremast being shorter than the main and no taller than the mizzen if there is one . Originally gaff - rigged , modern schooners typically carry a Bermuda rig . Such vessels were first used by the Dutch in the 16th or 17th century . They were further developed in North America from the early 18th century , and came into extensive use in New England . The most common type , with two masts , were popular in trades requiring speed and windward ability , such as slaving , privateering , blockade running , and offshore fishing . In the Chesapeake Bay area several distinctive schooner types evolved , including the Baltimore clipper , bugeye , and pungy . Schooners were also popular among pirates in the West Indies during The Golden Age of Piracy , for their speed and agility . They could also sail in shallow waters , and while being considerably smaller than other ships of the time period ( such as frigates and galleons ) , they could still hold enough cannons to intimidate merchant vessels into submission . Schooners were popular on both sides of the Atlantic in the late nineteenth and early twentieth centuries , long dominating yacht races such as the America 's Cup , but gradually gave way in Europe to the cutter . - A Bermuda rig, Bermudian rig, or Marconi rig is a configuration of mast and rigging for a type of sailboat and is the typical configuration for most modern sailboats. This configuration was developed in Bermuda in the 17th century; the term "Marconi" was a much later reference to the inventor Guglielmo Marconi whose wireless radio masts resembled the wires that stabilize the mast of a Bermuda rigged ship. - Guglielmo Marconi, 1st Marquis of Marconi (25 April 187420 July 1937) was an Italian inventor and electrical engineer known for his pioneering work on long-distance radio transmission and for his development of Marconi's law and a radio telegraph system. He is often credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy". - Bermuda is a British Overseas Territory in the North Atlantic Ocean. It is approximately east-southeast of Cape Hatteras, North Carolina; south of Cape Sable Island, Nova Scotia; and north of San Juan, Puerto Rico. The capital city is Hamilton. Bermuda is an associate member of CARICOM. - Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts"standing rigging", including shrouds and staysand which adjust the position of the vessel's sails and spars to which they are attachedthe "running rigging", including halyards, braces, sheets, vangs and halliards. - A sailboat or sailing boat is a boat propelled partly or entirely by sails smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture. Given the information, choose the subject and object entities that have the relation of 'subclass of'.
