How Much Weight Can Your Boat Float?
How much is your boat able to hold? A boat can only hold so much weight before it starts to sink. Too much weight on a boat can cause the boat to sway back and forth or roll over. It is very important to make sure that the load of your cargo is balanced or the chance of capsizing a boat is greatly increased.
When weight is added to a vessel, the boat will start to lower in the water, but it will not sink because of the shape of the hull. Many boats are designed with a flat-bottom because they are able to hold more in their cargo hold. The only problem with the flat-bottom design is weight distribution. If there is too much weight on one side than another, your boat is prone to capsize. Balance is a major priority for the flat-bottom. Too much weight on one size causes the boat to rock and tip. There is also a problem with overloading the vessel and making the boat sink because of its short side walls. The flat-bottom is also good for boating in shallow waters, they are very agile, and cheap to build. Smaller versions of these boats are called Jon boats. The bigger styles of the Jon boats are barges.
The second type of vessel bottom is a round with keel design. The keel design is a narrow V-shaped hull that extends underneath to create a centerline to keep it from rolling over in rough waters. A few problems with the rounded keel hull are that it cannot travel in shallow waters. This type of boat is also more expensive to build than a flat-bottom Jon boat.
The last type of boat hull is a multi-hull vessel. A multi-hull boat is the most expensive style of boat to build. The reason for this is that the hulls you want for your boat will depend on what you will use the boat for. If you are ...

Finally you will analyze the graphs you made by telling about the relationship between buoyancy and volume of the different boat hulls.
In the end, this experiment should have taught you how the different shapes of boat hulls effect how well your boat will be stable out on the water. The results from the experiment also have shown you that certain boat hull styles can support more weight than others. Another important finding was how weight distribution was a major factor because it can mean the difference between keeping your boat afloat or tipping over and capsizing. Now you know how a boat’s hull style affects how it floats.

In The fall of 2004 I purchased a boat and outboard. The company that built the boat also had the responsibility of mounting the out board. Unfortunately the company built the transom of the boat to high and this had a major effect on the boats performance. With the prop so close to the water’s surface the out board would ventilate ever time I tried to get the boat up on step. It would also ventilate on tight turns at high speeds. Unless I wanted to ship the boat back down to Seattle for modifications I would have to find a propeller that would operate effectively near the surface. The follow is some of the things I learned while solving this problem.
The paddle wheels were mounted either on the side or back of the boat. After the Civil War, the stern (back of the boat) paddle wheel was most popular. Although the paddle wheel is very large it draws just a few feet of water. The wheel spins about 18 times a minute with only four planks in the water for best speed. A steamboat travels about 15 miles an hour and 16 to 17 miles an hour on a swift river.
Ships do not sink because of displacement; the ship moves more water than the ship actually weighs.
On both the old "Clinton's Ditch" and in the early years of the Enlarged Erie Canal, both passenger boats (called "packets" or "packet boats"), usually horse-drawn, and working boats (also called "line boats" or "freighters"), drawn by either horses or mules, were common. Originally intended as a more comfortable alternative to the bone-jarring stagecoach, the packet boat fell out of favor as railroad travel improved, and basically disappeared by the latter half of the 1800s. On the current Erie (Barge) Canal, there being no towpath, line boats were replaced by tugboats ("tugs" or towing boats) with their attached barges, as well as motorized freighters. Today, the most common boats are recreational boats, although commercial traffic still
Their boats were long, but thin, so they were able to use the boats in rivers and in the ocean. Since the Hufflepuffs often lived in islands surrounded by swamps or the ocean the Hufflepuffs used their boats often. The boats had huge sails, sometimes bigger than the boats themselves, and when the wind was low they had oars so they were able to row their boats. Their boats did have a negative feature, which was capacity. He boats at the most were able to carry 20 people, so they often had a smaller amount of people during their trips, or traveled in multiple
Personal Watercrafts or "jet skis" are basically Personal Watercraft (PWC) are basically small inboard boats able to travel at high speeds due to large amounts of power and very light weight. Alomst all PWC's are under 600 lbs and most of todays PWC's have at least 90 hp.Not only are PWC's some of the fastest water vehicles they are also some of the most maneuverable water vehicles. This is because PWC's propultion is based on a jet that also is it's turning mechanism. When the driver turns the handlebars the jet (via cables) turns in the direction of the handlebars so the stern is pushed in the opposite direction. This allows the driver to turn at a much tighter angle than traditional boats with keels and rudders.The main drawback to this maneuverability is the fact that if there is no thrust coming from the engine the ability to turn is effictively zero meaning that anytime the driver presses the kill switch (a large red button) they lose all ability to steer. This is extremely dangerous whenever an inexperienced person may drive the PWC back to dock or into shore. PWC's have no brakes and have no ablilty to stop other than turning around. They have an extremely efficient ability to hydroplane (when most of the PWC is above water) and it takes most PWC's a few hundred feet to come to a stop after being at full throttle. This is because 600 lbs + a rider is traveling at a very high speed with only minimal friction to slow them down (since PWC's are made to travel with very little friction).
The Titanic worked like you would expect. Just like any other boat or ship, it floated because it weighed less than the amount of liquid it displaced. However, many factors contributed to the sinking of the Titanic. Rivets are very

As the water flooded into the first five compartments, the water would pass the water line. Once it passed the water line, the water would start to flood into the rest of the compartments like falling dominos. Since one-half of the ship kept flooding in with water, the water would slowly start to break the ship in half. Once one-half of the ship went under the other half that was floating above the water would snap and break off. Thus separating the Titanic into two pieces laying at the sea floor. The Titanic would ultimately sink on April 15, 1912. With the ship sinking, there are three factors on why the Titanic sank. The three factors are human error, corporate negligence, and design error. The three factors are equally responsible on why the ship sank.
As it filled with water, the bow submerged, raising the stern out of water. When the stern reached an angle of about 45 degrees, the stresses in the ship's midsection (15 tons per square inch) caused the steel to fail and the bow to rip loose and sink [Gannon, 1995].

The Titanic was the largest ship ever built back in the year of 1912. With the ship weighing 46,000 tons and almost 900 feet long it was deemed to be unsinkable. On April 12, 1912, the ship pulled away from the dock with 2,200 passengers of all different classes from rich to poor. On its maiden voyage, tragedy struck when it hit an iceberg along its travel. How did this ship that was declared to be unsinkable sink exactly? Human factors and the way the ship was built caused the tragedy of the sinking of the Titanic.
waves. The waves at the front of the boat are compressed and are shorter than the longer, spread out waves at the back of the boat.
Boat Building- Caribs’ canoes might have been up to 6 metres long. It was made out of tree trunks. The trunk was charred then hollowed with stone axes and left to season, after which it was buried in moist sand. Bars were placed across the opening to the force out the sides and it was left in place until wood had dried and hardened. Then triangular boards were wedged at the bow and stern so that the water could not enter the boat, and the sides were raised by fastening sticks bound with fibres and coated with gum to the upper edges.
Whether we are planning to build a boat or hoping to write a good essay, the only way to go about these tasks is to make a detailed plan of all the steps that need to be taken in order to get the desired result. If you spontaneously decide to build a boat, the result may be a plywood tub that leaks from all sides, let alone hold anyone in it.
