Nemo – Marine Design Tools for Rhino

Nemo is a parametric marine design plugin for Rhino 3D and Grasshopper. Its tools help naval architects and marine engineers generate vessel geometry, explore design variations and carry out preliminary analysis within their modelling workflow.

By linking geometry to design parameters, Nemo helps you assess changes to hull forms and marine components. Analysis results depend on the model, inputs and assumptions, and should be reviewed by a suitably qualified designer before being used for engineering or production decisions.

Parametric Hull & Ship Creation

Nemo provides tools for generating vessel geometry from dimensional and shape inputs. Parametric generators cover NACA profiles, hydrofoils, keels, rudders and sail plans, helping you explore alternatives and refine the geometry in Rhino and Grasshopper.

Intact Hydrostatics & Analysis

Hydrostatic tools help you calculate displacement, ship coefficients and other design data as the model changes. Nemo also supports offset tables, linesplan layouts and ship silhouette extraction.

For specialist software exchange, check the supported export format and receiving application's requirements. Test representative data before relying on an exchange workflow for project delivery.

Resistance Prediction & Structural Tools

Nemo includes Holtrop resistance prediction and ITTC frictional resistance calculations. Check each method's assumptions and applicability to the vessel under study rather than treating a prediction as a guarantee of performance.

Profile extrusion and nomenclature extraction tools support structural modelling and project documentation. Manufacturing readiness and regulatory requirements need separate professional assessment.
