Shipyard processes and pollutant sources

The shipbuilding and repair industry processes include surface preparation, painting and coating, metal plating and surface finishing, solvent cleaning and degreas- ing, machining and metal working, welding, vessel cleaning, and fiberglass operations. They consume various types of products and produce solid, liquid, and gaseous pollutants. Many different production processes employed in shipbuilding and repair require a vast amount of material inputs and generate huge amounts of waste and considerable emissions. Raw material inputs to the shipbuilding and repair industry are primarily steel and other metals, paints and solvents, blasting abrasives, and machine and cutting oils. In addition, a variety of chemicals are used for surface preparation and finishing such as solvent degreasers, acid and alkaline cleaners, and plating solutions containing heavy metal and cyanide ions. Pollutants and wastes generated include volatile organic compounds (VOCs), particulates matter (PM), waste...

Best Management practice BMP study in a Turkish shipyard

Best Management Practices are needed to reduce and prevent contamination of the aquatic environment and to improve air quality. Some BMP examples in shipbuilding industry are the treatment of paint washing water containing toxic metallic components cleaning of drydock and vessel before floated usage of alternative raw material such as tin-free, TBT-free, or low-VOC paint and filtration of volatile organic pollutants of main processes such as blasting, welding, and painting. A Best Management Practice (BMP) on a selected shipyard in Tuzla region was carried out as part of a postgraduate thesis (Celebi, 2008). Several meetings with the shipyard management were held. First the current situation in European shipyards was presented to the management in order to convince them of the benefits of BMP. After persuading, the management's first step was to examine the general situation of the shipyard. The project was completed successfully with the support of the management.

Early Human Environment Relationships

Humans migrating across the Bering Strait have occupied the Aleutian Islands for over 8000 years. The first stage of occupation by the Aleuts began in 6000 BP. Much debate exists on whether the Aleut civilization developed in relative isolation, or in contact with communities from the larger Bering Sea region. The Aleuts, however, became a sophisticated marine civilization, creating the bidarka, a kayak-like vessel suited to long hunting trips. The numbers and distribution of these early Aleuts fluctuated in response to volcanic activity, which would periodically alter the local ecology upon which they depended. By the time Russian explorers began colonizing the region in the 18th century, the Aleut population, dispersed throughout the chain, reached approximately 16,000, with principal settlements on islands that included Umnak, Unalaska, Atka, and Attu in the far west.

Factors Affecting Feasibility of Increased Nuclear Generation

The designs are also intended to be easier to build and less susceptible to construction delay through the use of modular construction techniques. Here, the approach is to construct many of the piping systems, platforms, and structures that make up the reactor systems in a factory remote from the construction site. Construction at the site is then limited to installing these systems and interconnecting them. Modular construction methods have long been in use in the shipbuilding industry and found to minimize schedule risk and improve quality, since much of the work is done in a factory environment not subject to the vagaries of weather. Using modular construction also enables the subassemblies to be fabricated anywhere in the world, making more facilities available. Such an approach is widely used in the aircraft industry for the construction of airliners such as the Boeing 757 and later aircraft.

Landscape diversity and productivity

A loose global network of free market economies is the backdrop against which much of today's science is being done. Utility of system components is therefore usually a strong motivation for conservation. In the case of biodiversity, landscapes which offer a stable mosaic of opportunity for human exploitation are considered desirable and worthy of conservation, in the Mediterranean basin, humans have for hundreds of years derived sustained benefit from functional attributes of ecosystems, and have been responsible for the maintenance of biodiversity for this reason. Blondel and Aronson (1995) refer to the long tradition of mixed agricultural production where rural communities historically combined cultivation with animal husbandry and the harvesting of products from natural forests in what the ancient Romans called the ager-saltus-siha (field-pasture-forest) system. These integrated systems relied on the diversity of terrains and climates which could support them. Such stable systems...

Evaluating Ecosystem Services Provided By Oyster Reefs

Second, improvements in water quality in general are valued by the general public who use estuarine habitats for activities such as swimming, boating, and sportsfishing. For instance, Bockstael et al. (1988, 1989) surveyed residents in the Baltimore-Washington area in 1984 and determined that their annual aggregate willingness to pay in increased taxes for moderate (i.e., 20 ) improvements in water quality (i.e., decreased nitrogen and phosphorous loading and increased sportsfish-ing catches) was over 100 million. The National Research Council (2004) used the consumer price index to adjust estimates reported in the preceding studies to 2002 price levels and reported that a 20 improvement in water quality along the western shore of Maryland relative to conditions in 1980 is worth 188 million for shore beach users, 26 million for recreational boaters, and 8 million for striped bass sportsfishermen. Although there are several potential sources of error in these estimates, they may be...

Challenges And Conclusions

Given that the value of augmented commercial fish landings surpasses oyster harvest values, the entire suite of ecosystem services that are sustained by intact reefs probably greatly exceeds the value currently derived from oyster harvests. Oyster restoration efforts at larger scales that enhance water quality potentially result in even larger benefits such as increased recreational use, heightened willingness to consume seafood, and reduced need for construction of wastewater purification systems. Water quality improvements from oyster restoration efforts and their economic values are more difficult to quantify however, current estimates of the willingness of boaters, beach users, and recreational fishermen from the Chesapeake Bay to pay for local improvements in the Bay's water quality suggest that oyster restoration efforts capable of achieving significant gains in water quality will result in economic returns derived from these changes that far exceed the value of current oyster...

Solvent cleaning and degreasing process and wastes

Shipyards use solvents in a variety of cleaning and degreasing operations including parts cleaning, process equipment cleaning, and surface preparation for coating applications. Some of the major solvents used are petroleum distillates, oxygenated solvents, and halogenated solvents. Most common cleaning and degreasing operations include cold cleaning and vapor degreasing (Kura et al., 1998).

Air Flotation Systems

Air Floatation And Precipitation

Air flotation is one of the oldest methods for the removal of solids, oil & grease and fibrous materials from wastewater. Suspended solids and oil & grease removals as high as 99 + can be attained with these processes. Air flotation is simply the production of microscopic air bubbles, which enhance the natural tendency of some materials to float by carrying wastewater contaminants to the surface of the tank for removal by mechanical skimming. Many commercially available units are packaged rectangular steel tank flotation systems shipped completely assembled and ready for simple piping and wiring on site. Models typically range from 10 to over 1000 square feet of effective flotation area for raw wastewater flows to over 1000 gallons per minute. Complete systems often include chemical treatment processes. A dissolved air flotation (DAF) system can produce clean water in wash operations where reduction of oil and grease down to 2 mg 1 is achievable in certain applications. In...

The Mesopotamians Southwest Asia 3700 bce to 1600 bce

Militarization and imperial endeavors also played a major role in the destruction of Mesopotamia's primary forests. The progressive deforestation of the region was closely correlated with the steadily growing capacity of Mesopotamian states to consume timber both for construction and for military purposes, in particular for naval shipbuilding.66 Massive quantities of wood were also required for commercial shipbuilding, bronze and pottery manufacturing, and building construction, including palaces and administrative offices.67 Thus, environmental sociologist Sing Chew argues that the crisis in agricultural productivity has to be understood within a wider context of the political-economic and ecological relations of Mesopotamia. The stratified centers of Mesopotamia pursued intensive socioeconomic activities to produce a surplus for domestic consumption as well as for export (in the form of grains and woolen textiles) to the Persian Gulf and beyond. The scale and intensity of economic...

Welding and cutting process and wastes

The primary raw material for ship construction is steel plates. All types of metal arriving at the shipyard are in standard size and length plates, shapes, and sections that may need customized sizing based on different requirements. Therefore, before welding, fabrication, and ship construction or repair, the material must be cut to required sizes, shapes, and lengths. Metal cutting in the shipyard is performed by either mechanical or thermal hot metal cutting operations (Kura et al., 1998). Various types of welding processes are used to join the different types of metals used in the construction of ships. Fusion welding, in particular, is performed at almost all locations in the shipyard. An important factor in welding processes is shielding. In most welding processes, this shielding is accomplished by addition of a flux, a gas, or a combination of the two.

Environmental and Economic Issues from Changing a Major Fuel Type as Energy Resource in an Industrial City in Korea

Ulsan is the largest industrial city of Korea with a population of more than 1.1 million people and national-scale industrial complexes (ICs) including non-ferrous metallic IC, petrochemical IC, automobile and shipbuilding IC. Main sources of air pollutants in major metropolitan cities are traffic emissions (Mamane et al., 2008). However, they are quite different from the main sources from industrial cities. According to the recent study of air pollution source apportionment (Koo and Kim, 2007), 77 , 66 , 87 , and 58 of the total sulfur oxides (SO*), nitrogen oxides (NO*), PM10, and volatile organic compounds (VOCs), respectively, are from point sources such as power plants and manufacturing plants in Ulsan. In Seoul, the capital city of Korea, with a population of 12 million people, however, 72 and 63 of the total emissions of SO* and VOCs are from area sources. Mobile sources are responsible for 16 , 83 , 93 , and 35 of the total emissions of SO*, NO*, PM10, and VOCs in Seoul,...

Universal City, and the Long Beach Naval Shipyard.

The Planet As Sacrifice Zone

The Bikini Atoll hydrogen bomb explosion, the largest ever, produced a mushroom cloud that rose 15 miles into the stratosphere. The fallout exposed some 229 Marshallese Islanders on Rongelap Atoll, including some US servicemen, and a crew of 23 workers on the nearby Japanese fishing boat Lucky Dragon, many of whom developed severe radiation sickness and died associated premature deaths. The Rongelapese were not evacuated from the islands until two days after the hydrogen bomb test. Using declassified government archival films and contemporary interviews, the Australia-based investigative journalist and cinematographer Dennis O'Rourke produced a film documentary titled Half Life (1986), presenting the restrained but chilling picture of a cynical radiation experiment on human populations sponsored by the military-industrial complex and condoned by Washington.

Archaeology Of The Arctic Scandinavian Settlement Of The North Atlantic

At the close of the 8th century, a link was established through the Baltic with northwestern Russia and further southward, thereby linking the North to the rich Islamic world. Thousands of Islamic silver coins reached southern Scandinavia in a few decades, and from around AD 800 the Scandinavian societies, situated on the fringe of continental Europe, all became part of a world system of exchange. This development, which brought the pagan Scandinavian societies to the scene in the following centuries, introduced an expansive period of Scandinavian history that, among other things, included the colonization of the North Atlantic. This phase in Scandinavian history is sometimes termed the Viking Age. The background for the expansion was partly the economical, social, and political development within late Iron Age societies in Scandinavia, including the development of a superior shipbuilding technology.

The Oceanic Realm Bering

The elders were from small-dot places like Kwigillingok, Quin-hagak, Mekoryuk, Toksook Bay, and Kipnuk, and they talked together about changes they had seen. Most had long histories of hunting and fishing in the Bering Sea, going back to the time of kayaks and harpoons and knowing how to navigate by reading the ocean currents. They had been told how things were by their own elders.

Archbishop Innocent Ivan Veniaminov

Veniaminov was received principally by the Aleut toion (chief) of Akun and Tigalda Islands in the district, Ivan Pan'kov. Bilingual, and a generation older than the young priest, Pan'kov became his mentor with regard to Aleut culture and language. Together, they traveled by kayak from village to village. Pan'kov served as translator until Veniaminov had learned Aleut. Eventually, they translated the Gospel according to Matthew into the Unalaska dialect of the Aleut language. They constructed an alphabet, based on Cyrillic letters with new characters introduced to represent special sounds in Aleut phonetics. Also,

Implications for international shipping

In 1993, Moscow commissioned a special research study with Norway and Japan to carefully explore the viability of using the Northern Sea Route, but its findings, published 6 years later, were very disappointing. Although the route had obvious advantages, ran the report of the International Northern Sea Route Programme, they were heavily outweighed by the sheer cost of building and operating ice-strengthened vessels, which would have to be used even if a Russian icebreaker travelled in front. Assuming these icebreakers would be available, the ships would have to be particularly small in order to get through the shallow straits in the New Siberian Islands and to keep strictly within the path cut by the Russian icebreakers. Such small ships would only be capable of carrying relatively small cargoes and were therefore far less commercially viable than their much bigger counterparts that made their way through the Suez Canal. The report also argued that, in...

Future RD Efforts

R& D efforts are aimed at overcoming technical barriers related to wave and tidal technologies and to salinity gradient. The main focus is on wave behaviour and hydrodynamics of wave absorption structure and hull design methods mooring power take-off systems and deployment methods. Typical research on tidal stream current systems can be divided into basic research that focuses on areas such as water stream flow pattern and cavitations and into applied science, which would examine supporting structure design, turbines, foundations and deployment methods.

Background

Water resource users, people such as fishermen, boaters, and swimmers, who use water in its natural settings lakes, streams, rivers, and estuaries. This category might even be assumed to encompass the fish, waterfowl, and other living things that depend on clean water to live, reproduce, and thrive. These users can be directly affected by the return flow of wastewater from water supply users.

Eliminating waste

The most straightforward and economical way to deal with waste would appear to be elimination. For example, any producers who can sell their product whole will not have a waste problem and, in some cases, can achieve the highest price for the product. Restaurants and markets in Asia often sell seafood live. But while this is relatively straightforward for crab and lobster, it becomes more difficult for suppliers of live fish. Fishing boats will need holding tanks, the fishermen must be taught how to handle the catch without harming it, and facilities and transport on land will need to be altered to accommodate live catch. Those who can enter this market most easily are aquaculturists who raise relatively small fish such as tilapia or flounder, since they start out with the facilities to maintain the fish alive, have collecting systems that cause minimum trauma to the animals, and offer species that are recognized and valued by Asian markets.

Egede Poul

Poul Egede, a Danish-Norwegian missionary to Greenland, is sometimes known as the Apostle to North Greenland because of his missionary activities in that region among the native Inuit population. Poul Egede was the son of Hans Egede (see Egede, Hans), himself styled the Apostle to Greenland. He moved to Greenland with his parents and brother Niels (1710-1782) at the age of 13 in 1721. He assisted his father in missionary activity, since he quickly learned Greenlandic, as well as Greenlandic ways of hunting and handling kayaks. In 1728, he moved to Copenhagen (in Denmark). Despite a personal leaning toward a maritime career, he accepted his father's guidance and took a degree in theology in 1734, as well as holy orders, the same year that his brother Niels became a merchant and bookkeeper in Godthab (in Greenlandic, Nuuk) until he too returned to Denmark, in the company of his father, in 1736. That same year, Poul again traveled to Greenland where, from 1736 to 1740, he served as a...

Ellis Henry

In 1748, a year after their return, Ellis published his description of the land and its people at H. Whitridge in London. The same year the clerk of the California, Theodore Swaine Charles Drage, also published his own account of the voyage. Drage's book only includes one engraving of an Inuk in his kayak, but Ellis's original report was richly illustrated with two maps and nine copperplate engravings depicting the Arctic landscape, the animals, and Inuit involved in everyday activities such as fire drilling, sealing, and kayaking. Even though Drage's book supplements Ellis's observations, because several times they searched in two separate groups, it never received the same attention as Ellis's report. In his report, Ellis attempted exhaustive descriptions of the Esquimaux Indians (Ellis, 1748) they had encountered on several occasions. He especially admired the kayak, described their warm fur clothing, the different hunting equipment, their winter and summer dwellings, and also...

Previous situation

A visit was paid to the shipyard in order to see the general situation of the shipyard before the application of BMP. Safety issues, threats to workers' health and environmental risks were obtained. Scrap metal sheets and used paint boxes were lying around the production area (see Fig. 39.4) the used grid blasting abrasives were not removed from the area. Also welding workers were not using necessary protective equipment during their work. When production processes such as painting and blasting, which are main cause of waste and pollutants, were observed, it was seen that there was no waste management policy of the shipyard. As a first step for waste management, a waste material billboard (see Fig. 39.5) was located in the shipyard where workers could easily see. production processes going on mutually, it is a difficult task to make workers change their habits as to waste management. However, it is good to see in the shipyard that the workers know what to do...

Industrial Changes

In the nineteenth century there was a flourishing trade in ice between the USA and India. In the winter, blocks of ice were cut from the frozen lakes in New England, packed in wood shavings and taken by sailing ship to Calcutta. Surprisingly enough, sufficient ice survived the journey to be available to make ice cream during the hot summer. This useful commercial activity was killed stone dead as soon as refrigerators were invented. Another example is provided by indigo, a dye that was highly prized from ancient times. In India, two million acres Another type of difficulty arises when the Government or the industry itself insists, for good reasons, on new safety precautions. These inevitably increase the price of the product and may make it uncompet-itive compared with similar industries in other countries, which are not subject to the same regulations. This situation may be worsened if the workers in the other countries are willing to work for longer hours for lower wages. It is then...

Iceland

The history of fishing in the waters around Iceland goes back hundreds of years, but is mainly centered round Atlantic cod, the preferred species in northern waters in olden times. Demersal fisheries at Iceland fall into two categories the local land-based fisheries conducted by Icelanders, and those of distant water foreign fleets. Until the late 19th century, the Icelandic fisheries were primarily conducted with open row-boats, while the distant water fishing fleets consisted obviously of much larger, decked ocean-going sailing vessels. Until the last decade of the 19th century, almost all fishing for demersal species at Iceland, whether from small open rowboats or larger oceangoing sailing vessels, was carried out by hand lines. It has been estimated that the combined landings by Icelandic, Dutch, and French fishing vessels were in the order of 35,000 t annually in the period 1766-1777. One hundred years later, the combined French and Icelandic catches averaged about 55,000 t....

University of Miami

The teaching research facilities include chemical laboratory instrumentation, a laboratory onboard a cruise ship for collecting marine and atmospheric data, a 90-ft. research catamaran, and a simulation wind and wave tank for observation of specific air sea interactions. RSMAS's library holds an extensive marine science collection.

Frobisher Sir Martin

Frobisher spent a fortnight exploring the first 40 leagues of Frobisher Bay and trading with the Inuit, until they captured five of his crew. Reduced to a crew of 13, and deprived of their ship's boat, Frobisher responded by taking an Inuit hostage, but failed to negotiate an exchange before weighing anchor for England with the captive and his kayak. Although the Inuk died soon after reaching London on October 9, he was a public sensation. A greater sensation attended a black stone that Frobisher presented to Lok, who consulted three assayers before finding one who declared the stone laden with gold. A second expedition was organized to return to

Aron From Kangeq

Rink probably selected a key group of manuscripts and sent them to Aron so that the artist might choose which stories to illustrate. Scholars know from the two men's correspondence that Rink provided Aron with his materials, which were scarce in Greenland at that time. Rink supplied paper, pencils, and pigments from Godthab to Kangeq via kayak. In late 1858, Rink introduced Aron to wood carving as a printmaking method. The first two volumes of Kaladlit Oqalluktualliait Gronlandske Folkesagn (published in 1859 and 1860) as well as the newspaper Atuagagdliutit (started in 1861) featured Aron's woodcut illustrations. He earned national recognition for these and the picture book Pr0ver af Gr0nlandsk Tegning og Trykning 1857-61 Examples of Greenlandic Drawing and Printing , a gift to King Frederik VII of Denmark.

Common Harbor Seal

In earlier days, Inuit hunters harpooned various species of phocids on the ice and in the water, but with the introduction of firearms they resorted to the more efficient method of shooting them. Unlike the ringed or bearded seals, harbor seals do not use breathing holes, but climb out of the water on sandbars or icefloes. They must be approached carefully because the first shot often drives the whole group into the water. Unlike other seals, which attempt to escape when wounded, harbor seals sometimes turn on the hunters or dive deeply, and are considered dangerous to hunt. Where the ocean surface does not freeze solid, seals come to open spaces between ice-floes for air in these areas, Inuit hunters pursue the seals in kayaks or stand by the floes, hoping for a chance to throw their harpoons. After the Inuit hunter locates such a space, he stand with a poised harpoon, awaiting the quivering of a small, slender piece of baleen, or whalebone, stuck through the thin ice surface, which...

Bearded Seal

The only country to have ever had commercial harvesting of this species is Russia, where in the Sea of Okhotsk and Bering Seas annual catches exceeded 10,000 animals in some years during the 1950s and 1960s. Quotas were established to reduce hunting, and catches dropped to a few thousand bearded seals annually in the 1970s and 1980s in these regions. However, bearded seals are an important subsistence resource for coastal peoples throughout much of the Arctic. Their meat is a favorite food in some northern communities, and their thick leather has in the past been used for covering kayaks and making rope.

Chlorinated solvents

39.2.3 Waste management in shipyards Waste management practices differ for developed and developing nations, for urban and rural areas, and for residential and industrial producers. Management for non-hazardous residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for non-hazardous commercial and industrial waste is usually the responsibility of the generator. The methods for shipyard waste management are described below.

The pulse

The Arctic pack ice extended so far south that Eskimo fishing boats landed on the northern coast of Scotland. They didn't meet much opposition, because the hungry Highlanders had abandoned their crofts after grain harvests had failed for seven straight years, and had gone raiding for food in the lowlands to the south. In the 1690s temperatures in Scotland were more than 3 F below normal snow lay on the ground long into the summer. Those who stayed behind were reduced to eating nettles and making bread from tree bark. The political repercussions of this Scottish turmoil are still with us today. The king became so worried by fears of insurrection that he shipped off angry clansmen and their starving families to set up Presbyterian colonies in Catholic Northern Ireland. And eventually, after widespread famine in the 1690s brought despair about the future for the Scots as a nation, the clan chiefs forged a union with England. fell by up to 3-6 F in northern Europe, and the Eskimos reached...

Doldrums

The location of the ITCZ can have dramatic effects on rainfall in equatorial locations, resulting in wet and dry seasons in the tropics, rather than the cold and warm seasons characteristic of higher latitudes. Regions in the ITCZ receive precipitation more than 200 days per year. Within the ITCZ surface winds are slight, unlike the zones north and south of the equator where the tradewinds blow. For this reason, sailors named this belt of calm the doldrums due to the stagnation they found their sailing ships in after days of no wind, high heat, and humidity.

Aleutian Tradition

One of the most spectacular aspects of the Aleutian Tradition is the ancient Aleut skill at mummification of the dead. Many of these mummies were individuals of high status, and when interred in caves they were perfectly preserved for up to 2000 years. This preservation allowed archaeologists to investigate many aspects of the Aleutian Tradition that are not preserved in the ancient village sites. These include baskets, mats, clothing, hats, masks, bags, shields, armor, spears, bows and arrows, kayaks, and many other aspects of perishable material culture.

Why study glaciers

Some are personal, some academic, and some socially significant. To me, the personal reasons are among the most important glaciers occur in spectacular areas, often remote, that have not been scarred by human activities. Through glaciology, I have had the opportunity to live in these areas to drift silently in a kayak on an ice-dammed lake in front of our camp as sunset gradually merges with sunrise on an August evening to marvel at the northern lights while out on a short ski tour before bedtime on a December night and to reflect on the meaning of life and of our place in nature. Maybe some of you will share these needs, and will choose to study glaciers for this reason. I have found that many glaciologists do share them, and this leads to a comradeship which is rewarding in itself.

Trade Winds

Winds, or easterlies, carried air from east to west at low latitudes and are less regular over land areas than they are over the oceans. The trade winds meet at the Intertropical Convergence Zone. The doldrums (downward branch of the Hadley Cell, named for George Hadley, whose 1735 paper linked rising air and the Earth's rotation in causing the trade winds) are the calm winds at the Intertropical Convergence Zone in the area between latitude 5 degrees N and latitude 5 degrees S, where a sailing ship might not move because of the calm winds. In satellite imaging, the Intertropical Convergence Zone appears as a band of clouds. The strength and position of the Intertropical Convergence Zone influences tropical and global weather patterns.

Piracy

Various governments are encouraging this trend. The European Commission, for example, wants to help 'maintain the competitive lead of European shipyards in developing technology required for Arctic conditions', and thinks that that 'the potential to provide specially designed, environment-friendly ships, including icebreakers, is an important asset for the future'. It also wants to 'improve maritime surveillance capabilities in the far north' and is working closely with the European Space Agency to build a polar-orbiting satellite system that can pick up signals from anywhere in the world. 'If successful', the Commission claims, then 'this would allow a better knowledge of ship traffic and mean that emergencies could be responded to more quickly. The Galileo satellite navigation system will also play an

Fulmar

The Icelandic name fulmar means foul gull. Fulmars are petrels and the name undoubtedly was given because of their superficial resemblance to gulls, and in reference to the bird's oil-spitting habit. All petrels defend their individual distance by spitting stomach oil, and the northern fulmar is particularly dextrous, shooting gobs of oil with sudden lunges of its open beak. The Russian name glupysh means foolish, and refers to the birds' trustfulness. The birds are easily caught even by landing-net from the boat while they feed on offal from fishing boats. The Norwegian name is havhest.

How To Have A Perfect Boating Experience

How To Have A Perfect Boating Experience

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
