First, find the volume of displacement, then multiply the ship’s length, beam, and draft. Divide the displacement by this product to find the block coefficient.

A Block Coefficient Calculator helps estimate the block coefficient of a ship, an important measure of its hull shape. This tool is used in naval architecture to assess the ship’s design and performance in water.
Formula:
Where:
| Variable | Meaning |
|---|---|
| CB | Block coefficient |
| V | Volume of displacement (m³) |
| L | Length of the ship (m) |
| B | Beam (width of the ship, m) |
| T | Draft (depth of the ship, m) |
Example Calculation:
Let’s say a ship has a displacement volume (V) of 12,000 m³, a length (L) of 100 meters, a beam (B) of 20 meters, and a draft (T) of 10 meters. Using the formula, we can calculate the block coefficient (CB).
| Step | Calculation |
|---|---|
| Volume of displacement (V) | 12,000 m³ |
| Length (L) | 100 meters |
| Beam (B) | 20 meters |
| Draft (T) | 10 meters |
| Block coefficient (CB) |
Answer: The block coefficient is 0.6.
What is a Block Coefficient Calculator?
A block coefficient calculator is used to calculate the block coefficient (CB), which represents the fullness of a ship’s hull shape.
The block coefficient is the ratio of the volume of displacement to the volume of a rectangular block with the same overall dimensions of length, beam, and draft. It is an important parameter for naval architects and ship designers, as it helps determine the ship’s resistance and performance in the water.
This calculator helps answer questions such as “how to calculate block coefficient?” and “what is meant by block coefficient?”. It is widely used in designing different types of ships, including bulk carriers and tugs.
The block coefficient varies depending on the shape of the ship, with bulk carriers generally having a higher block coefficient compared to faster, more streamlined vessels.
