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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chine (boating)
A chine in boat design is a sharp change in angle in the Cross_section_(geometry), cross section of a hull (watercraft), hull. The chine typically arises from the use of sheet materials (such as sheet metal or marine ply) as the mode of construction. Rationale of chines Using sheet materials in boat construction is cheap and simple, but whereas these sheet materials are flexible longitudinally, they tend to be rigid vertically. Examples of steel vessels with hard chines include narrowboats and widebeams; examples of plywood vessels with hard chines include sailing dinghies such as the single-chined Graduate (dinghy), Graduate and the double-chined Enterprise (dinghy), Enterprise. Although a hull made from sheet materials might be unattractively "slab-sided", most chined hulls are designed to be pleasing to the eye and hydrodynamics, hydrodynamically efficient. Hulls without chines (such as Clinker (boat building), clinker-built or Carvel (boat building), carvel-built vessels) u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheer (ship)
The sheer is a measure of longitudinal main deck curvature, in naval architecture. The sheer forward is usually twice that of sheer aft. Increases in the rise of the sheer forward and aft build volume into the hull, and in turn increase its buoyancy forward and aft, thereby keeping the ends from diving into an oncoming wave and slowing the ship. In the early days of sail, one discussed a hull's sheer in terms of how much "hang" it had. William Sutherland's ''The Ship-builders Assistant'' (1711) covers this information in more detail. The practice of building sheer into a ship dates back to the era of small sailing ships. These vessels were built with the decks curving upwards at the bow and stern in order to increase stability by preventing the ship from pitching up and down. Sheer on exposed decks also makes a ship more seaworthy by raising the deck at fore and aft ends further from the water and by reducing the volume of water coming on deck.

Ralph Munroe
Ralph Middleton Munroe (April 3, 1851 – August 20, 1933) was an American yacht designer and early resident of Coconut Grove in south Florida. His home, now The Barnacle Historic State Park, is the oldest house in Miami-Dade County still standing in its original location. Early life Munroe was born to Thomas and Ellen Middleton Munroe at their family home on 22nd Street near 4th Avenue in New York City on April 3, 1851. Munroe's grandfather was William Munroe who made the first American lead pencils in 1812. In 1854, the Munroe family moved to Clifton, Staten Island where Munroe spent his childhood. He lived in a large home at 104 Townsend Avenue. Growing up near the sea, he became fascinated with the boats that were essential to island life. The New York Yacht Club America's Cup Race was held near his childhood home in Clifton. While a student at Eagleswood Military Academy, near Perth Amboy, New Jersey, from 1861 to 1864, he purchased the "Hornet" for a mere $2.00, the fir ...

Schooner
A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner. The origins of schooner rigged vessels is obscure, but there is good evidence of them from the early 17th century in paintings by Dutch marine artists. The name "schooner" first appeared in eastern North America in the early 1700s. The name may be related to a Scots word meaning to skip over water, or to skip stones. The schooner rig was used in vessels with a wide range of purposes. On a fast hull, good ability to windward was useful for priv ...

Gaff Rig
Gaff rig is a sailing rig (configuration of sails, mast and stays) in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) called the ''gaff''. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays. The gaff enables a fore and aft sail to be four sided, rather than triangular. A gaff rig typically carries 25 percent more sail than an equivalent Bermudian rig for a given hull design. A sail hoisted from a gaff is called a gaff-rigged (or, less commonly, gaff rigged or gaffrigged) sail. Description Gaff rig remains the most popular fore-aft rig for schooner and barquentine mainsails and other course sails, and spanker sails on a square rigged vessel are always gaff rigged. On other rigs, particularly the sloop, ketch and yawl, gaff rigged sails were once common but have now been largely replaced by the Bermuda rig sail, which, in addition to bei ...

The Carolinas
The Carolinas are the U.S. states of North Carolina and South Carolina, considered collectively. They are bordered by Virginia to the north, Tennessee to the west, and Georgia to the southwest. The Atlantic Ocean is to the east. Combining North Carolina's population of 10,439,388 and South Carolina's of 5,118,425, the Carolinas have a collective population of 15,557,813 as of 2020. If the Carolinas were a single state of the United States, it would be the fifth-most populous state, behind California, Texas, Florida, and New York. The Carolinas were known as the Province of Carolina during America's early colonial period, from 1663 to 1710. Prior to that, the land was considered part of the Colony and Dominion of Virginia, from 1609 to 1663. The province, named ''Carolina'' to honor King Charles I of England, was divided into two royal colonies in 1729, although the actual date is the subject of debate.

Ohio
Ohio () is a state in the Midwestern region of the United States. Of the fifty U.S. states, it is the 34th-largest by area, and with a population of nearly 11.8 million, is the seventh-most populous and tenth-most densely populated. The state's capital and largest city is Columbus, with the Columbus metro area, Greater Cincinnati, and Greater Cleveland being the largest metropolitan areas. Ohio is bordered by Lake Erie to the north, Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Ohio is historically known as the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes". Its state flag is the only non-rectangular flag of all the U.S. states. Ohio takes its name from the Ohio River, which in turn originated from the Seneca word ''ohiːyo'', meaning "good river", "great river", or "large creek". The state arose from the lands west of the Appalachian Mountai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Lake Superior, Superior, Lake Michigan, Michigan, Lake Huron, Huron, Lake Erie, Erie, and Lake Ontario, Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Lake Michigan–Huron, Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water ...

Chesapeake Bay
The Chesapeake Bay ( ) is the largest estuary in the United States. The Bay is located in the Mid-Atlantic (United States), Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula (including the parts: the Eastern Shore of Maryland / Eastern Shore of Virginia and the state of Delaware) with its mouth of the Bay at the south end located between Cape Henry and Cape Charles (headland), Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of District of Columbia. The Bay is approximately long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
