Wetted Surface Area Calculator

Introduction

In naval architecture and ship design, understanding the wetted surface area (WSA) of a vessel is essential for assessing its hydrodynamic characteristics and overall performance. The Wetted Surface Area Calculator provides a valuable tool for maritime professionals and enthusiasts to quickly and accurately determine this critical parameter. In this article, we’ll explore the significance of wetted surface area, the formula used by the calculator, and how to effectively use this tool in ship design and analysis.

The Significance of Wetted Surface Area

The wetted surface area of a vessel refers to the portion of its hull that is in contact with the water. This area plays a crucial role in determining resistance, drag, and the overall efficiency of the vessel’s movement through the water. Calculating the wetted surface area is fundamental for naval architects, ship designers, and engineers involved in optimizing vessel performance.

The Wetted Surface Area Formula

The formula to calculate the wetted surface area (WSA) is expressed as:

$WSA=WLL\times (B+D)$

Where:

• $WSA$ is the wetted surface area in square feet.
• $WLL$ is the water line length in feet.
• $B$ is the beam (width) of the vessel in feet.
• $D$ is the draft (submersion depth) of the vessel in feet.

This formula illustrates that the wetted surface area is proportional to the water line length and the sum of the vessel’s beam and draft.
