About Nautical Solver

What is Nautical Solver?

Nautical Solver is an independent web platform operated and maintained by an engineering-focused developer, providing free-to-use calculators for naval architecture and marine engineering.

The platform was created to simplify access to commonly used engineering relationships applied in preliminary design, operational analysis, and technical cross-checking—without relying on opaque or black-box software.

Tools are organised by discipline, including hull design, resistance, propulsion & power, stability, navigation, and regulatory metrics, supporting both learning and professional workflows.

Who is this for?

• Students studying naval architecture or marine engineering who want to explore relationships between principal dimensions, coefficients, and vessel performance.
• Marine engineers and naval architects who need quick preliminary estimates or independent calculation cross-checks.
• Operators and technical staff performing operational evaluations related to speed, power, fuel consumption, trim, or stability.

The platform is publicly accessible, free to use, and does not require user registration, subscriptions, or paid access.

Scope & limitations

Calculations provided on Nautical Solver are intended for educational use, research, and preliminary engineering assessment only. While the implemented methods are widely accepted and documented, results should not be used as the sole basis for final design, construction, or operational decisions.

Users are encouraged to verify outputs against detailed hydrostatic calculations, classification society rules, model tests, CFD analyses, and applicable regulatory requirements where appropriate.

Supporting the project

Nautical Solver is offered as a free and open-access engineering tool. There are no subscriptions, paywalls, or paid features.

If you find the site useful and would like to support its ongoing development and maintenance, you may optionally do so via Buy Me a Coffee. Contributions are entirely voluntary and do not affect access to any features or content.
