Boating is the leisurely activity of travelling by boat, or the recreational use of a boat whether powerboats, sailboats, or man-powered vessels (such as rowing and paddle boats), focused on the travel itself, as well as sports activities, such as fishing or waterskiing. It is a popular activity, and there are millions of boaters worldwide. Types of boats Boats (boat types) can be categorized into 3 different types types of board categories, unpowered, motor boats, and sailboats.Recreational boats (sometimes called pleasure craft, especially for less sporting activities) fall into several broad categories, and additional subcategories.

Protected Areas Of Nebraska
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

Gavins Point Dam
Gavins Point Dam is a long embankment rolled-earth and chalk-fill dam which spans the Missouri River and impounds Lewis and Clark Lake. The dam joins Cedar County, Nebraska with Yankton County, South Dakota a distance of 811.1 river miles (1,305 km) upstream of St. Louis, Missouri, where the river joins the Mississippi River. The dam and hydroelectric power plant were constructed as the Gavins Point Project from 1952 to 1957 by the United States Army Corps of Engineers as part of the Pick-Sloan Plan. The dam is located approximately 4 miles (6.4 km) west or upstream of Yankton, South Dakota. History and background Gavins Point Dam was constructed as a part of the Pick–Sloan Missouri Basin Program, authorized by the Flood Control Act of 1944 by Congress. The dam is named after Gavins Point, a bluff along the northern bank of the Missouri River named for an early settler, now within the western end of Lewis & Clark Recreation Area, which was to be the original locat ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Zebra Mussels
The zebra mussel (''Dreissena polymorpha'') is a small freshwater mussel. The species originates from the lakes of southern Russia and Ukraine, but has been accidentally Introduced species, introduced to numerous other areas and has become an invasive species in many countries worldwide. Since the 1980s, the species has invaded the Great Lakes, Hudson River, and Lake Travis. The species was first described in 1769 by German zoologist Peter Simon Pallas in the Ural River, Ural, Volga River, Volga, and Dnieper River, Dnieper Rivers. Zebra mussels get their name from a striped pattern commonly seen on their shells, though it is not universally present. They are usually about the size of a fingernail, but can grow to a maximum length around . Shells are D-shaped, and attached to the substrate with strong Byssus, byssal fibers, which come out of their umbo (bivalve), umbo on the dorsal (hinged) side.

Waterfowl
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins the galliformes. These two groups only occupied two ecological niches during the Mesozoic, living in water and on the ground, while the toothed enantiornithes were the dominant bird ...

Big-game Hunting
Big-game hunting is the hunting of large game animals for meat, commercially valuable by-products (such as horns/antlers, furs, tusks, bones, body fat/oil, or special organs and contents), trophy/taxidermy, or simply just for recreation ("sporting"). The term is often associated with the hunting of Africa's "Big Five" games (lion, African elephant, Cape buffalo, African leopard, and rhinoceros), and with tigers and rhinoceroses on the Indian subcontinent. History Hunting of big game for food is an ancient practice, possibly arising with the emergence of ''Homo sapiens'' (anatomically modern humans), and possibly pre-dating it, given the known propensity of other great apes to hunt, and even eat their own species. The Schöningen spears and their correlation of finds are evidence that complex technological skills already existed 300,000 years ago, and are the first obvious proof of an active (big game) hunt. ''H. heidelbergensis'' already had intellectual and cognitive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowmobiling
A snowmobile, also known as a Ski-Doo, snowmachine, sled, motor sled, motor sledge, skimobile, or snow scooter, is a motorized vehicle designed for winter travel and recreation on snow. It is designed to be operated on snow and ice and does not require a road or trail, but most are driven on open terrain or trails. Snowmobiling is a sport that many people have taken on as a serious hobby. Older snowmobiles could generally accommodate two people; however, most snowmobiles manufactured since the 1990s have been designed to only accommodate one person. Snowmobiles built with the ability to accommodate two people are referred to as "2-up" snowmobiles or "touring" models and make up an extremely small share of the market. Most snowmobiles do not have any enclosures, except for a windshield, and their engines normally drive a continuous track at the rear. Skis at the front provide directional control. Early snowmobiles used simple rubber tracks, but modern snowmobiles' tracks are usu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Skating
Ice skating is the self-propulsion and gliding of a person across an ice surface, using metal-bladed ice skates. People skate for various reasons, including recreation (fun), exercise, competitive sports, and commuting. Ice skating may be performed on naturally frozen bodies of water, such as ponds, lakes, canals, and rivers, and on man-made ice surfaces both indoors and outdoors. Natural ice surfaces used by skaters can accommodate a variety of winter sports which generally require an enclosed area, but are also used by skaters who need ice tracks and trails for distance skating and speed skating. Man-made ice surfaces include ice rinks, ice hockey rinks, bandy fields, ice tracks required for the sport of ice cross downhill, and arenas. Various formal sports involving ice skating have emerged since the 19th century. Ice hockey, bandy, rinkball, and ringette, are team sports played with, respectively, a flat sliding puck, a ball, and a rubber ring. Synchronized skating ...
