why do boats return to an upright position after a gust of wind??

Question

i need a website that explains why.... thanx

Answer 1

People are right, this does have to do with buoyancy, but there are some other factors that can be discussed if you want a thorough explanation.

For a website that explains some basics about ship stability try Wikipedia.
The second link (below) is a presentation from UC Berkeley about ship stability - in case you have some other questions that the Wiki page isn't clear about.

For some real in depth study you can check out the reference books sold at http://www.sname.org - the official website for the Society of Naval Architects and Marine Engineers. Most of my text books for my B.Sc. in Naval Architecture & Marine Engineering were SNAME publications.

Answer 2

Boats are designed with a low center of gravity to make them stable and keep them upright. Sailboats have a lower center of gravity to counter the force of the wind acting on the sails. The lower the center of gravity, the greater the righting moment, the ability to return to an upright position.

Answer 3

Buoyancy and balance. If no or poor center of balance they wont return to an upright position. If the are to top heavy they will continue to roll over and not return to an upright. Balance is an important part of design. So is buoyancy . If displacement is such that your boat floats like a rock the slightest wave or wind can tip it and sink. Degree of pitch and roll characteristics vary considerably and again are an important part of design.

Answer 4

I'll explain why. Because the bilateral symmetry of the hull causes the water to be displaced evenly to the starboard and port. If you tilt the ship in one direction or the other, one side will be displacing more water than the other. When that happens, the law of entropy (the second law of thermodynamics) states that unequally balanced energetic state will right itself by sending the more complex (higher energy) state in the direction of the less complex, lower energy state. Ie, the ship tilts back the other way. In this way, the ship acts like a pendulum until it resonates itself down to a point where the friction of movement in the water exceeds the energy of the last resonance cycle, and then the ship is standing upright in the water.

Answer 5

I don't know a website in particular, but boats return to neutral because of ballast and keel, centerboard, etc.. Also, the way that the boat is shaped contributes to how high or low it sits in the water and it's balance.

Answer 6

Assuming you're talking about a sailing boat... the weight of the keel gives them a very low centre of mass, which keeps them upright - most of the time :-)

Answer 7

cause they have rudders that go deep into the water that serve as stabilizers. Also, the boat is designed in a way that makes it want to stay upright.

Answer 8

I don't know of any websites.....but the boat is just returning to it's natural state before it was acted upon by an outside force.

It'sjust physics.

Answer 9

It the way the boats are designed they are built so that if it rolls over that is will right its self
