What is the difference between list and heel?
A list reduces the stability of the vessel. When a list is corrected by increasing the displacement mass, the additional weight should be placed as low as possible in the vessel. A vessel is said to be heeled when it is inclined by an external force, e.g. from waves or the wind.
What is the difference between list and loll?
Angle of loll is the state of a ship that is unstable when upright (i.e. has a negative metacentric height) and therefore takes on an angle of heel to either port or starboard. Angle of list is caused by unequal loading on either side of centre line of vessel.
How much can a ship list?
In fact, in extreme cases, a ship can actually list 60 degrees and recover, according to Burke. An angle of 90 degrees would be the ship lying on its side. This figure is not arbitrary, it’s based on complex computer modelling and wave pool tests.
What is trim and list of ship?
LIST is defined as transverse inclination of vessel due to weight of cargo on ship( generally uneven distribution of cargo in ship’s cargo hold) either direction. This is transverse inclination of the vessel. Whereas TRIM is the transverse inclination of the vessel due to wind, Current and other natural factors.
How do you correct an angle in a list?
An angle of loll can be corrected only by lowering the centre of gravity, not by moving loads transversely. This can be done by moving weight downwards, adding water ballast in double bottom tanks or removing weight above the ship vertical centre of gravity.
What is a trim on a ship?
The trim of a ship describes its floating position in length direction, namely if the bow or the aft of the ship is deeper submerged into the water. The trim can have a significant impact on a vessel’s energy demand for propulsion during sailing.
What does it mean when a ship is listing?
“Listing” is a nautical term to describe when a vessel takes on water and tilts to one side. A ship can list either to port (left) or starboard (right). By contrast, a ship is said to be “trimming” when she tips forward or backward.
What is another name for a boat?

Is it a boat or a ship?
A boat is a small to mid-sized vessel, which has much lesser cargo carrying capability as compared to a ship. Ships are specifically made to carry cargo or passengers or boats, whereas boat is a generic term used for a variety of water crafts. Oct 4 2019
What are the different yacht parts?
Anchor: An anchor is a heavy item that is dropped down into the water, touching the bottom of the body of water and securing the vessel. Fenders: Made of plastic or rubber, the fenders prevent a vessel from moving onto a pier. Gunnel: Also known as the gunwale, this is an edge along the side of a boat.
