Phil Bolger
Philip C. Bolger (December 3, 1927 – May 24, 2009) was a prolific American boat designer, who was born and lived in Gloucester, Massachusetts. He began work full-time as a draftsman for boat designers Lindsay Lord and then John Hacker in the early 1950s. Bolger's first boat design was a 32-foot (9.75 m) sportfisherman published in the January 1952 issue of ''Yachting'' magazine. He subsequently designed more than 668 different boats, from a 114-foot-10-inch (35 m) replica of an eighteenth-century naval warship, the frigate '' Surprise'' (ex-''Rose''), to the 6-foot-5-inch (1.96 m) plywood box-like dinghy Tortoise. Although his designs ranged through the full spectrum of boat types, Bolger tended to favor simplicity over complexity. Many of his hulls are made from sheet materials — typically plywood — and have hard chines. A subclass of these designed in association with Harold Payson called ''Instant Boats'' were so named because they were intended to be easily built b ...

Gloucester, Massachusetts
Gloucester () is a city in Essex County, Massachusetts, in the United States. It sits on Cape Ann and is a part of Massachusetts's North Shore. The population was 29,729 at the 2020 U.S. Census. An important center of the fishing industry and a popular summer destination, Gloucester consists of an urban core on the north side of the harbor and the outlying neighborhoods of Annisquam, Bay View, Lanesville, Folly Cove, Magnolia, Riverdale, East Gloucester, and West Gloucester. History The boundaries of Gloucester originally included the town of Rockport, in an area dubbed "Sandy Bay". The village separated formally from Gloucester on February 27, 1840. In 1873, Gloucester was reincorporated as a city. Contact period Native Americans inhabited what would become northeastern Massachusetts for thousands of years prior to the European colonization of the Americas. At the time of contact, the area was inhabited by Agawam people under sachem Masconomet. Evidence of a village exis ...

Dovekie 21
The Dovekie 21, often called just the Dovekie, is an American sailing dinghy, named for the Little auk, sea bird. It was designed by Phil Bolger as a Cruising (maritime), cruiser and first built in 1978.Sherwood, Richard M.: ''A Field Guide to Sailboats of North America, Second Edition'', pages 114-115. Houghton Mifflin Company, 1994. Production The design was built by Edey & Duff in the United States. It was reported in 1994 that 152 examples had been completed, but it is now out of production. Design The Dovekie is a recreational sailboat, built predominantly of fiberglass over an Airex foam core. It has a catboat rig with an aft-raked mast and a wishbone boom. The hull is flat-bottomed, with a raked stem, a canoe stern, a spade-type rudder controlled by a tiller and dual retractable leeboards, with a retractable bow centerboard. It displaces and carries no ballast. The boat has a Draft (hull), draft of with a leeboard extended and with it retracted, allowing Beaching (n ...

Trimaran
A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") which are attached to the main hull with lateral beams. Most modern trimarans are sailing yachts designed for recreation or racing; others are ferries or warships. They originated from the traditional double-outrigger hulls of the Austronesian cultures of Maritime Southeast Asia; particularly in the Philippines and Eastern Indonesia, where it remains the dominant hull design of traditional fishing boats. Double-outriggers are derived from the older catamaran and single-outrigger boat designs. Terminology The word "trimaran" is a portmanteau of "tri" and "(cata)maran", a term that is thought to have been coined by Victor Tchetchet, a pioneering, Ukrainian-born modern multihull designer. Trimarans consist of a main hull connected to outrigger floats on either side by a crossbeam, wing, or other form of superstructure—the traditional Polynesian terms f ...

Sustainable Fisheries
A conventional idea of a sustainable fishery is that it is one that is harvested at a sustainable rate, where the fish population does not decline over time because of fishing practices. Sustainability in fisheries combines theoretical disciplines, such as the population dynamics of fisheries, with practical strategies, such as avoiding overfishing through techniques such as individual fishing quotas, curtailing destructive and illegal fishing practices by lobbying for appropriate law and policy, setting up protected areas, restoring collapsed fisheries, incorporating all externalities involved in harvesting marine ecosystems into fishery economics, educating stakeholders and the wider public, and developing independent certification programs. Some primary concerns around sustainability are that heavy fishing pressures, such as overexploitation and growth or recruitment overfishing, will result in the loss of significant potential yield; that stock structure will erode t ...

Lewis Francis Herreshoff
L. (Lewis) Francis Herreshoff (November 11, 1890 – December 1972), was a boat designer, naval architect, editor, and author of books and magazine articles. Early in his career he worked for the Herreshoff Manufacturing and for naval architect Starling Burgess. Biography Herreshoff was born on November 11, 1890, in Bristol, Rhode Island, to Clara Anna DeWolf (1853–1905) and Nathanael Greene Herreshoff (1848–1938). In 1926, after naval service and work for Starling Burgess, he went into business for himself in Marblehead, Massachusetts, as a designer of racing and pleasure yachts, canoes, kayaks and other small craft. Herreshoff died December 1972. Herreshoff was inducted into the National Sailing Hall of Fame in 2014.

Howard I
Howard is an English-language given name originating from Old French Huard (or Houard) from a Germanic source similar to Old High German ''*Hugihard'' "heart-brave", or ''*Hoh-ward'', literally "high defender; chief guardian". It is also probably in some cases a confusion with the Old Norse cognate ''Haward'' (''Hávarðr''), which means "high guard" and as a surname also with the unrelated Hayward. In some rare cases it is from the Old English ''eowu hierde'' "ewe herd". In Anglo-Norman the French digram ''-ou-'' was often rendered as ''-ow-'' such as ''tour'' → ''tower'', ''flour'' (western variant form of ''fleur'') → ''flower'', etc. (with svarabakhti). A diminutive is "Howie" and its shortened form is "Ward" (most common in the 19th century). Between 1900 and 1960, Howard ranked in the U.S. Top 200; between 1960 and 1990, it ranked in the U.S. Top 400; between 1990 and 2004, it ranked in the U.S. Top 600. People with the given name Howard or its variants include: Given ...

Hull Speed
Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, and usually its crest-to-trough dimension (height) increases as well. When hull speed is exceeded, a vessel in displacement mode will appear to be climbing up the back of its bow wave. From a technical perspective, at hull speed the bow and stern waves interfere constructively, creating relatively large waves, and thus a relatively large value of wave drag. Ship drag for a displacement hull increases smoothly with speed as hull speed is approached and exceeded, often with no noticeable inflection at hull speed. The concept of hull speed is not used in modern naval architecture, where considerations of speed/length ratio or Froude number are considered more helpful. Background As a ship moves in the water, it creates standing waves that oppose its movement. Thi ...

Sharpie (boat)
Sharpies are a type of hard chined sailboat with a flat bottom, extremely shallow draft, centreboards and straight, flaring sides. They are believed to have originated in the New Haven, Connecticut region of Long Island Sound, United States. They were traditional fishing boats used for oystering, and later appeared in other areas. With centerboards and shallow balanced rudders they are well suited to sailing in shallow tidal waters. Traditional sharpies New Haven sharpies Sharpies first became popular in New Haven, Connecticut, towards the end of the 19th century. They came into use as a successor to the dugout log canoe and most likely were derived from the flatiron skiff. In an 1879 edition of Forest and Stream, a man named James Goodsell of the Fair Haven neighborhood claimed to have built the first sharpie with his brother in 1848. His claim was never contested. The Goodsell & Rowe Oyster Barn is shown on Front Steet in an 1850 Map of Fair Haven which is now in Yale's Beine ...
