Nordhavn 40/II - tawler:
Beam: 14' 6"
Draft: 5' 2"
Hinckley T40 - jet boat:
Beam: 12' 5"
Draft: 2' 3"
I would say that these are the extremes. A semi displacement hull would run anywhere between these two.

The beam of a boat is the measured width of the broadest part of a vessel
Beam...the widest part of a boat
The definition of beam is the widest part of the boat
that is where the water level is when the boat is in the water.

It is the boat's draft.
The term you are referring to is "draft". The draft of a boat is the depth of water needed for it to float clear of the bottom.
The distance between the bottom and the keel of a boat is the draught (British English).
To calculate the draft of a boat, measure the vertical distance from the waterline to the bottom of the hull (keel) when the boat is in the water. This measurement can be taken using a sounding line or by checking the boat's specifications if available. The draft can vary based on factors like load and water conditions, so it's important to take measurements under typical operating conditions. Additionally, ensure that the boat is level, as an uneven load can affect the draft.
