The process of manufacturing a land sailor began with researching sailing, how a land sailor works and what allows for a land sailor to perform well. From the research it was found for a land sailor to maximize performance the land sailor has to be as lightweight as possible but not too light that when applied with wind the land sailor would topple over. In addition to the land sailor, the sail had to reach 45 degrees to the source of the wind where beyond that point the land sailor would not move. Also with the sail battens needed to be used to help keep the shape of the sail and to prevent the sail from flapping uncontrollably.
From the information gathered a rough sketch of the land sailor was produced, which had included rough measurements. From there some of the materials needed were gathered such as the plywood and timber as this

was what we worked on first. A piece of timber, 700 by 35, was cut, which now became the main body of the chassis. Next, two pieces of plywood was cut out to the dimensions of 400 by 35, and two blocks of timber was cut out to square pieces 35 by 35. As seen in the picture to the right the pieces of material cut out were assembled together using PVA glue and 15mm nails. Then a 9mm hole was drilled into the body of the chassis to the far right. However, it seemed impractical to have the hole there, as the flag would be facing towards the bow of the land sailor, thus making us having to make the bow wider creating more weight. Then a second hole was drilled but towards the bow making the flag face towards the stern. Furthermore, another hole was drilled for the wheels at the front. The front of the land sailor was curved to allow for a smoother ride once in motion. From here a dowel rod was cut to 75 and two pipes were cut to 10. As seen in the picture the front wheels were assembled. Need to past picture here. After that, the wheels were drilled out using the drill machine and plywood as the material where the wheels were cut to a 70mm diameter. Once the wheels were cut out garnet paper was used to remove the rough edges of the wheels but leaving the outer circumference to ensure that the wheels would have grip or some sort of friction when in motion. To be able to have the wheel on the side, a drill was used to predrill a hole for the nail to be then screwed on. Once that was done, a washer was put onto the nail, then the wheel and then another washer was used to prevent the wheel from touching either side of the nail and chassis. The screw was tightened enough so that the wheel would not wiggle around too much. The next step in the process was to work on the sail.
Two pieces of dowel rod was cut out to 740 and 385. Next a piece of (material for sail) was cut out to form a simple sail shape of dimensions of, 760 by 400 to account for that the edges would wrap around the mast and boom. Duct tape was used to keep the wrapped edges as tight as possible and also at where the sail meets the mast near the bottom to further secure the sail.
Three battens were used and placed horizontally across the sail and secured with duct tape. Then the outer edge of the sail was stapled down to make prevent the flapping of the sail as seen in the picture. In addition to making the sail stronger, two pieces of plywood, find dimensions, as seen in the picture were attached near the tack of the sail to strengthen the boom and to also ensure that the sail does not blow away when wind is applied.
The final step of the process was the drill another hole for the key where it was serve as an attachment of the flag to the rear of the chassis through string. Here, then the flag was placed into the hole and that was the process of creating the land

“The Boat”, narrated by a Mid-western university professor, Alistar MacLeod, is a short story concerning a family and their different perspectives on freedom vs. tradition. The mother pushes the son to embrace more of a traditional lifestyle by taking over the fathers fishing business, while on the other hand the father pushes the son to live more autonomously in an unconstrained manner. “The Boat” focuses on the father and how his personality influences the son’s choice on how to live and how to make decisions that will ultimately affect his life. In Alistair MacLeod’s, “The Boat”, MacLeod suggest that although dreams and desires give people purpose, the nobility of accepting a life of discontentment out weighs the selfishness of following ones own true desires. In the story, the father is obligated to provide for his family as well as to continue the fishing tradition that was inherited from his own father. The mother emphasizes the boat and it’s significance when she consistently asked the father “ How did things go in the boat today” since tradition was paramount to the mother. H...
‘’The only easy day was yesterday’’, is a famous saying for recruits that are doing physical training and mental challenges to become Navy Seals. Who are the Navy Seals? What do they do? Well, the name Navy Seal is named after the environment in which they operate, sea, air and land and there are the foundation of Special Warfare combat forces. They are organized, trained and equipped to conduct a variety of special operations missions. (Navy SEALs: Special Operations for the U.S. Navy. )
This paper investigates why Donald McKay is the father of American clipper ships. He was born in Shelburne, Nova Scotia, September 4, 1810.2 When Donald was sixteen years old he had the desire to learn the trade of ship building, so he went to New York. In 1826 New York was the worlds best shipbuilder and shipbuilding was America’s leading industry. McKay decided that in order to learn the trade he must obtain an apprenticeship. So he became an apprentice to Isaac Web who has appropriately been called the “Father of Shipbuilders”. This is because more successful master shipbuilders came out of Web’s shipyard than from any other place in America.3 At the conclusion of his apprenticeship he went on to work for Brown & Bell. In 1832 packet building was the best and most readily available work in New York. The majority of these ships were built at Isaac Web’s, Brown & Bell’s, and Smith & Dimon’s. At this time McKay was what would be called a free lance ship wright. McKay then married Albenia Martha Boole the eldest daughter of John Boole.4 At this time McKay then went to Newburyport and formed a partnership with William Currier.
As the propeller rotates (fig 3-1) it forces water down and back as this is happening water must move into the void created by the spiraling blades. This creates a pressure differential across the blade- Low pressure on the back side and high pressure on the front side. This causes water to be sucked into the propeller and accelerated out the back (fig 3-3) much like a house-hold fan (fig 3-2). This action creates the thrust that drives a boat.
Actually the idea is quite simple really, it consists of a floor above the hull with open drain plugs in the rear of the boat and above the water line. By this simple method as water comes in to the boat it will drain right out of the back. If too much weight is in the boat then water will simply come in through the drain holes. This is no worry to me because I can always just put some plugs in the drain holes when carrying a heavy load. I made the decision to build the aluminum skiff 17ft long and strong enough to hold an outboard motor with a mass of 141kg (approx. mass of 90Hp Mercury).
number for your traps, you need a large flat bottom boat with a powerful motor.
Bjorn Ericksen and his team have embarked on a long and expensive project designed to help them win the next Whitbread World Sailboat Race. Using the above proposed plan, the team should be well prepared to design, build and sail their vessel to victory. Although they are certain to experience setbacks, problems and delays, having a priority matrix, a project network, and a Gantt chart will provide a solid plan that will easily keep their project on track. Once they have finished the race and reviewed their performance, defending their championship will become next year's objective.
When used on sail boats, hydrofoils can increase the top speed by quite a bit. Once the hull of the sail boat is out the the water the drag from the water is much less. Simply explained, there is less surface area "rubbing" on the water to slow the boat down. This means that even with gentle winds, a small boat can really get moving.

How does a sailboat sail? One might be able to explain how a sailboat sails down wind, because almost everyone has seen some debris, such as a plastic bag drifting through the wind. The cause of this is the force of the wind pushing the bag and this force of the wind is greater than the force of resistance so the result is the movement of the bag. But, how does a sailboat sail against the wind and how does a sailboat sail faster than the wind? Aerodynamics and lift allow this to occur.
Who would've thought that 94 percent of life on Earth is aquatic, that makes us land occupants a very small portion of the overall life on Earth. With this being said, ocean exploration is essential in gaining knowledge on what we are sharing our planet with. The oceans continue to provide many medical benefits with their many plants and animals.
Boat builders use many materials to build the actual boat and also many techniques. One technique is the "Stitch and Glue" construction. It uses high grade marine plywood, simple wire sutures, f...

Sailing has been around for millennia, and is considered to be one of the earliest and most environmentally friendly methods of water transport. Sailboats act as a method of transportation, exercise, and entertainment. These now more structurally developed and masterfully modeled ships have been engineered for efficiency, and these advancements have ensured durability and speed among modern sailboats. The great strength and ability of sailboats has given competitive owners the opportunity to participate in races, but generally sailboats have come to exist as more of a relaxed hobby. The expensive activity of sailing is demanding both physically and mentally, as it tests anticipative abilities and endurance. To understand the physics concepts at work in a sailboat is immensely advantageous, as it can generally improve one’s performance.
