About Nautical Solver
Practical naval architecture and marine engineering calculators, built for clarity, speed, and real-world use.
What is Nautical Solver?
Nautical Solver is an independent web platform providing free-to-use calculators for naval architecture and marine engineering. The site focuses on commonly used engineering relations applied in preliminary design, operational analysis, and technical verification.
The tools are organised by discipline — including hull design, resistance, propulsion & power, stability, and regulatory metrics — and are intended to support both learning and professional workflows.
Unlike black-box software, Nautical Solver emphasises transparency. Inputs, assumptions, and calculation steps are presented clearly so users can understand, verify, and adapt the results.
Who is this for?
- Students studying naval architecture or marine engineering who want to understand relationships between principal dimensions, coefficients, and performance.
- Marine engineers and naval architects who need quick preliminary estimates or independent cross-checks.
- Operators and technical staff performing operational calculations related to speed, power, fuel consumption, or stability.
The platform is free to use and does not require registration, subscriptions, or paid access.
Scope & limitations
Calculations provided on Nautical Solver are intended for educational use and preliminary engineering assessment. While the methods implemented are widely accepted and documented, results should not be used as the sole basis for final design decisions.
Users are encouraged to verify outputs against detailed hydrostatics, class rules, model tests, CFD analyses, and applicable regulatory requirements where appropriate.
