Re: What is it called when a boat leans side to side

If you're talking about a sail boat, while underway, its called heeling. Its from the wind acting against the sails. For any boat, with no other external factors involved, say the boat is on a mooring and she starts to "tilt" its called a list and is a very bad thing.

Rolling. Forward and aft is pitching. Not really a calculation thing I think. Round bilges with wineglass crossection may roll more than a more beamy boat with a sharper turn at the beam and leading into the keel. maybe google boat rolling and see what pops up as examples....

here is a comparison, the flatter bottom (B, C) will roll less, but have a quicker, more snappy action. Of course it's not that simple...

Boats yaw,roll,and pitch. Just like a plane (airship). A naval architect has standard calculations to estimate as does the Coast Guard.

In fact, software exists to compute the rolling motion of a ship (as well as pitching, yawing, heaving swaying and surging), taking into account the hull shape (including appendages), the mass distribution, the wave spectrum of energy, the control algorithm for the rudders/stabilizing fins... Just google "seakeeping software".

Finally, someone with some sense!

Sometimes my buckets are amused by Chucklet's comments, other times they're scared!

It's just awful the amount of abuse they have to go through when trolls attack!
