What else can I help you with?
Which of these hulls is a displacement hull?
a displacement hull is like a canoe's hull... it displaces water
What is the Maori word for Hull?
In Maori the hull of a canoe is called 'Kohiwi'.
What does the hull do on a boat?
Basically, the hull on a boat keeps out the water, and displaces the water to create buoyancy, which enables the boat to float.
What is the main frame or body of a ship?
The main frame or body of a ship is called the hull. It is the watertight body of a ship that provides structure and buoyancy. The hull determines the ship's stability, strength, and seaworthiness.
Why don't kayaks sink?
Same way as anything else - displacement, in that the mass of water displaced by the canoe's hull is greater than the mass of the canoe itself. This means the canoe is effectively less dense than water and so has positive buoyancy and will float.
What is a characteristic of a catamaran a hull?
A catamaran hull is one having either dual hulls or a main hull and secondary hull (three hulls is a trimaran). Like an outrigger canoe, having a dual base in the water means that a catamaran is usually more stable than a single hull. The reduction in the "roll" of the hull can result in a smoother ride.
Why would a canoe sink if there is a leak in it?
B/ the hull would no longer displace water - as waster would be inside.
How submarines float on water?
The air trapped in the hull (this includes the buoyancy tanks) make it lighter than the water it displaces. The buoyancy tanks surround the main hull (where the people and machinery are), and can be flooded to allow the ship to sink. Refilling them with air (from compressed air tanks) allows it to return to the surface.

What makes the shape of a speed boat float?
A speed boat floats due to its hull design, which is shaped to displace water and create buoyancy. The hull shape allows the boat to stay afloat by pushing water aside as it moves through the water, creating an upward force that counteracts the force of gravity. Additionally, air compartments in the hull provide added buoyancy, helping the boat stay on the surface of the water.
Why is the boat floating in the sea?
Its called buoyancy When a solid surface such as a boats hull is placed into water, it will only sink if first is heavy enough to fall into the water and second, if the water is able to fill it up and make it heavy in the first place.
Where was the copper sheathing fitted on the HMS alarm and why?
It was fitted on the hull. This is because copper is an antifouling material so marine organisms have great difficulty attaching. Without marine organisms (fouling) there is less resistance and the boat can go much faster.
