What is Wetted Surface Area?

Wetted surface area is a measure of the surface area of a boat or ship that is in contact with water. It is crucial for understanding the hydrodynamic properties of the vessel, including resistance and drag.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ WSA = 30 \times (10 + 5) = 450 \text{ ft²} \]

The Wetted Surface Area is 450 ft².

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ WSA = 40 \times (12 + 6) = 720 \text{ ft²} \]

The Wetted Surface Area is 720 ft².
