Yantrah runs published naval architecture methods — resistance & powering, propulsion, intact and damage stability, structural screening, regulatory compliance, outfitting and machinery — and returns grounded numerical outputs with full method citation. 17 engines across six groups. It sits between a designer's first sketch and the class drawings.
Several engines reference standards that carry copyright: ISO 12217, IACS Unified Requirements, SOLAS, and classification rules. Yantrah holds only the method and citation — never the standard text itself. If you intend to use a result for regulatory purposes, you need a licensed copy of the cited standard to verify it at source. This is a condition of use, not a platform limitation.
Every result is qualified — it follows a published engineering method, names the source, and states the method's applicability limits. It is not certified. Not reviewed by a classification society. Not approved for regulatory submission. Not a substitute for a competent naval architect's judgement. Use every output as a screener that tells you where to look and what to size — not as a document you sign off on.
Concept explanations grounded in naval architecture fundamentals. No sign-in required.
Full engine access — resistance, powering, stability, structural screeners, compliance and outfitting at concept stage.
Concept stage and parametric pre-design only. Not for final design, structural drawings, production planning, or class submission. Not applicable outside the stated limits of each method's source. Confirm all results with a qualified naval architect or classification society surveyor before acting on them.
