    Analysis Of Honest Trailers: What I Learned In Boating School

    The premise of Honest Trailers depict movies in an overtly literal way; by that statement, the creators of Honest trailers can categorize their work and type of work as being New Critics. Through this type of criticism, more focus is put on the movie and its “intrinsic” values versus director’s purpose, representing the historical period or presenting psychological factors (Mays 2333). Main ideas played out by the movie trailers depict the artists’ styles throughout the production of the movies, the artists’ use of figurative language, and the organic unity that further represents universal, human themes.…

    The Open Boat Personification

    The universe that humans currently exist in is so enormous that our minds cannot grasp how immense it is. There are terms that were invented to help us understand it more efficiently, however, even with our modern technology, we only get about half way to comprehending our universe. For example, the nearest star is Alpha Centauri, it is approximately twenty-five trillion miles away from Earth. Light travels over one-hundred and eighty thousand miles per second, even then, it would take light over four years to arrive there if it left from our planet. Does this not make you feel small and insignificant? This is precisely how the narrator felt in Stephen Crane’s, “The Open Boat”, as he and his men were floating among the vast sea, in a thrilling yet dangerous experience. One of the most fervent metaphysical questions about life and the universe is the notion explored in this…

    Open Boat

    Determination was what the sailors from “The open boat had,” with their drive into finding land and there hope into finding shore would they not give their lives into the cold heartless ocean. Days after days of seeing the ocean at its worst and days with no food could they only have hope and determination to finding land and being safe? As weak as they were they relied on each other to get through it. With the captain being emotionally distraught about losing his ship he still had the strength to lead the few men he had left into unknown of the sea. The men of the open boat had a lot of trouble they had to face together with losing one of their members of the crew in the process of getting to shore, but with their faith and persistence led them to find land.…

    Comparing The Return And A Marker On The Side Of The Boat

    Nothing in this world is permanent, changes are brought into our lives and how we deal with it depends upon ourselves. Whether we accept it or not, changes affect who we are in the future. Both Kamau in The Return and the narrator in A Marker on the Side of the Boat portray how they dealt with changes around them as a result of a war that occurred in their beloved home places. Their passive decision to accept reality lead to a positive outcome that has not made their lives miserable, but instead those depraved memories remain as an experience to move on and find more meaning with life.…

    The Boat

    In “The Boat” by Alistair Macleod, the boat, and the ill-fitting clothes he wore significantly represent the confinement and the father’s inability to break free from tradition, reinforcing that tradition can suppress one’s dream for greater things. To begin, the boat itself is a symbol of the fathers bounding to the sea, showing his obligation to follow customs. The boat is categorize with a “marine clutch and a high speed reverse gear and was painted on an oblong plate across her stern. Jenny Lynn had been my mother’s maiden name and the boat was called after her as another link in the chain of tradition”(Macleod 3) The high speed reverse gear depicts how the father is not moving forward along with the light green name of Jenny Lynn that demonstrates the father’s sacrifice for the fishing custom to support his family. The Jenny Lynn that he receives through tradition gives him a constant reminder that his way of life may never change and that his dreams are out of his reach. Furthermore, the clothing in his closet symbolizes the father’s imprisonment with tradition. The narrator mentions “his ill-fitted serge suit, the two or three white shirts that strangled him and the square black shoes that pinched” (Macleod 4) The square black shoes that pinched him means that the life of fishing that he inherits does not fit, the life he lives is simply to overpowering that it damages him. The white shirts that suffocates him shows the struggles he faces everyday that he is unable to separate from. His attire is so inflexible that it was leaving him trapped in one place incapable to grasp his own desires. Lastly, at the father’s death his departure speculates that it is suicide to liberate his son and himself from an unhappy future bringing the fishing tradition with him. When the father’s body is discovered “the white green stubble of his whiskers had continued to grow in death. Physically as he lay there with the brass chains on his wrist and seaweed in his hair”(Macleod…

    The Open Boat

    "None of them knew the color of the sky." This first sentence in Stephen Crane's "The Open Boat" implies the overall relationship between the individual and nature. This sentence also implies the limitations of anyone's perspective. The men in the boat concentrate so much on the danger they are in, that they are oblivious and unaware to everything else; in other words, maybe lacking experience. "The Open Boat" begins with a description of four men aboard a small boat on a rough sea. The central theme of this story is about confronting Nature itself. "The Open Boat" is Stephen Crane's account from an outsider's point of view of the two days spent in a small boat. The correspondent is autobiographical in nature; Stephen Crane was shipwrecked off the coast of Florida while working as a war correspondent. The correspondent in "The Open Boat" portrays the author. Mainly through the correspondent, Crane shows the power of nature and how one man's struggle to survive ultimately depends on fate.…

    The Row-Row Your Boat Philosophy

    One of the first topics that we discussed in my English class is the “Row Row Row Your Boat” philosophy. In a video posted by Prince Ea, this idea is presented. Many valuable points are made by him, although three main points, which are applicable to life, stood out to me. Firstly, take control of your own life and remember that you are the one “rowing your boat.” Likewise, it is crucial that you remember to move with the flow of life and do not try to force things in life. Lastly, the video discusses the potential we possess to influence others and their future. Considering how easy it is to forget our purpose in life, this video is used as an inspiration and a reminder for all of us, including you and I, to keep on rowing our…

    Boat People

    The Vietnamese Boat people are refugees who have fled their country in the late 1970’s and early 1980’s. Refugees from Laos, Cambodia, and especially Vietnam are referred to as “boat people” because they fled their respective countries. Refugees from these countries were fleeing shortly after the Vietnam War had ended. The Vietnam War was a cold war which took place from November 1st, 1955 until April 30th, 1975. On April 30th, 1975 was the day that the fall of Saigon took place, essentially this means that communists took power of the government. The Communist government set up “re-education camps” for people who still believed in the old government, in these camps 165,000 people died, 1 to 2 million people was imprisoned for no apparent reason when the communist government took over, no formal charges or trials were given. Furthermore, at least 200,000 southern Vietnamese were executed, and tens of thousands of Vietnamese people committed suicide when the communist government took over. Essentially, these countries became so poor they were unable to feed themselves and this resulted in famine which led to many deaths in the 1980’s. With all these occurrences it ultimately led to the destruction of Vietnam and caused many people to become refugees “Boat People”.…

    Comparing The Open Boat And To Build A Fire

    Nature is indifferent to humans, nobody is important to the universe, and everybody is subject to fate -- all ideas that are strongly supported by naturalists. Naturalists have a very realistic and grim view of life: Naturalists believe that all humans are unimportant because there is no god. “The Open Boat” by Stephen Crane and “To Build a Fire” by Jack London, both short stories written by naturalist authors, share a common theme: nature is completely indifferent to the suffering of humans. “The Open Boat” follows a group of men that are stranded in the ocean on a lifeboat after they have survived a shipwreck. The men’s main focus throughout the short story is to reach land safely, and they eventually do after having a few very close calls…

    The Open Boat

    Symbolism allows writers to suggest their ideas within a piece of literature. This is found in most types of writing. Stephen Crane expresses this in his short story, The Open Boat. Through symbolism and allegory, it is demonstrated that humans live in a universe that is unconcerned with them. The characters in the story come face to face with this indifference and are nearly overcome by Nature's lack of concern. This is established in the opening scenes, the "seven mad gods" and in the realization of the dying soldier. The descriptions that Crane uses in the opening scenes illustrate nature's lack of concern for their tragedy. He discusses the waves in the ocean that continually roll and crest. The waves are problems or situations that are unavoidable; moreover, the "waves" continue to flow one after another towards the poor rowers. Also, the "birds sat comfortably in groups, and they were envied by some in the dingey" because the birds were indifferent towards the sailors' situation. They were sitting happily as if nothing was going on around them. The sailors were envious of this because they were forced to confront nature's trials. The sun continues to rise and set daily, maintaining this routine regardless of what occurs in the world. The shore is also "lonely and indifferent." This indifference causes the men to feel a certain isolation from nature. The men feel as if fate (the "seven mad gods") controls their destinies. Their thoughts are given: "If I am going to be drowned…why, in the name of the seven mad gods who rule the sea…If this old ninny-woman, Fate, cannot do better than this…" However, the men realize that there is no "fate" and that there is no purpose for where they are. There is also a shark that is "playing around" near the boat; curiously, it does not seem to even acknowledge their presence. The realization that they have no purpose brings them to the brink of despair. In the beginning of the story, the author describes the "dawn…

    Fairplay 22 is a Tug Vessel; a tug vessel is used to assist a seagoing vessel whereas the vessel who needed assistance may be encountering technical problems or to assist difficult manoeuvres for example mooring.
