What Is Length To Beam Ratio

The length to beam ratio is a fundamental measurement in ship design. It is calculated by dividing the length of the vessel by its beam (width). A higher ratio often indicates a faster but less stable vessel, while a lower ratio suggests a more stable but slower vessel.

Formulas and Variables

To calculate the Length to Beam Ratio, you can use the following formula:

LBR=LB\text{LBR} = \frac{L}{B}

Variables

Variable Description
LBR Length to Beam Ratio
L Length of the side (ft)
B Length of the beam (ft)

How to Calculate Length to Beam Ratio

  1. Identify the length of the side (L).
  2. Identify the length of the beam (B).
  3. Divide the length (L) by the beam (B) to get the Length to Beam Ratio (LBR).

Calculation Example

1. Basic Example

Variable Value
Length of the Side (L) 50 ft
Length of the Beam (B) 10 ft
Length to Beam Ratio (LBR) 5.00
  1. Enter length of the side: 50 ft.
  2. Enter length of the beam: 10 ft.
  3. Compute LBR: LBR=5010=5.00\text{LBR} = \frac{50}{10} = 5.00

2. Advanced Example

Variable Value
Length of the Side (L) 75 ft
Length of the Beam (B) 15 ft
Length to Beam Ratio (LBR) 5.00
  1. Enter length of the side: 75 ft.
  2. Enter length of the beam: 15 ft.
  3. Compute LBR: LBR=7515=5.00\text{LBR} = \frac{75}{15} = 5.00

How to Use Calculator

Using the calculator is straightforward:

1. Enter the length of the side (in feet) into the input field labeled “Length of the Side (ft)”.

2. Enter the length of the beam (in feet) into the input field labeled “Length of the Beam (ft)”.

3. The calculator will automatically compute the Length to Beam Ratio (LBR) and display it.

Example Input Values

  • Length of the Side: 50 ft
  • Length of the Beam: 10 ft

FAQ

Q: What is the length to beam ratio?

A: The length to beam ratio is a measurement that compares the length of a vessel to its beam (width). It helps in assessing the vessel’s stability and speed.

Q: How do I calculate the length to beam ratio?

A: Use the formula Length to Beam Ratio = Length / Beam for basic calculations or the advanced formula for detailed analysis involving draft and displacement.
