Nemo – Marine Design Tools for Rhino

Nemo is the leading parametric marine design plugin for Rhinoceros 3D and Grasshopper, specifically engineered for naval architects and marine engineers who leverage computational design for rapid vessel iteration. By providing a dedicated suite of tools for automated hull generation, ship silhouette extraction, and performance analysis, Nemo enables you to explore complex vessel designs with absolute geometric precision and responsiveness.

In the modern maritime industry, Nemo bridges the gap between traditional naval architecture and algorithmic design. It allows for the creation of information-rich models where every component—from hull form to structural profiles—is driven by parametric relationships, ensuring that your vessel remains manufacture-ready and technically sound throughout the entire design process.

Advanced Parametric Hull & Ship Creation

Nemo introduces specialized tools for generating 3D vessel geometry based on specific dimensional and shape constraints. Its library of parametric generators includes NACA profiles, hydrofoils, keels, rudders, and sail plans, allowing for the rapid creation of performance-oriented marine components. The software is optimized for the fairness and smoothness required for high-end naval design, providing the parametric control to fine-tune your NURBS surfaces for optimal hydrodynamic performance.

Integrated Intact Hydrostatics & Analysis

One of the core value-add features of Nemo is its efficient hydrostatic solver, providing immediate computing of ship coefficients and hydrostatic data as you modify your design. Nemo excels in hull analysis by automating the generation of offset tables and linesplan layouts directly within the Rhino workspace. Its unique ability to extract ship silhouettes and export data to specialist maritime software—including IGES for Maat Hydro (Sistre) and points for Mars 2000 (Bureau Veritas)—makes it a critical link in the professional maritime engineering pipeline.

Resistance Prediction & Tooling

Nemo includes a suite of tools for predicting vessel performance, including Holtrop resistance prediction and frictional resistance calculations (ITTC 57' and 78' models). Beyond analysis, Nemo provides specialized structural tools for the automatic extrusion of profiles and the extraction of nomenclature for project management. This integrated approach ensures that your marine designs are not only technically verified but also optimized for structural weight and manufacturing efficiency.
