- A vessel's length at the waterline (abbreviated to L.W.L) is the length of a ship or boat at the level where it sits in the water (the waterline). The LWL will be shorter than the length of the boat overall (length overall or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL.

Length at the waterline (LWL) is the length from the forwardmost point of the waterline measured in profile to the stern-most point of the waterline. Length between perpendiculars ( LBP or LPP ) is the length of the summer load waterline from the stern post to the point where it crosses the stem .
If the length of waterline is given in metres and desired hull speed in knots, the coefficient is 2.43 kn·m −½. The constant may be given as 1.34 to 1.51 knot·ft −½ in imperial units (depending on the source), or 4.50 to 5.07 km·h −1 ·m −½ in metric units, or 1.25 to 1.41 m·s −1 ·m −½ in SI units.

They are: Length Overall ( LOA) is the extreme length from one end to the other. Length on the Waterline ( LWL) is the length from the forwardmost point of the waterline measured in profile to the stern-most point of the waterline. Beam or breadth ( B) is the width of the hull.
