Recommended Open Source Software

FreeCAD

Parametric 3D CAD modeler with ship design workbench. Excellent for structural design and weight calculations.

OpenFOAM

Computational Fluid Dynamics (CFD) tool for analyzing hydrodynamic performance of hulls/foils.

SALOME

CAD/CAE integration platform for structural analysis and meshing.

QCAD

2D CAD for creating detailed construction drawings and schematics.

LibreCAD

2D CAD alternative with good DXF compatibility for structural drawings.

Estimated Weight Breakdown

Note: This tool provides estimates based on standard marine aluminum construction. For detailed structural design, use CAD/CAE software like FreeCAD with the ship design workbench. Weight calculations assume 6061-T6 aluminum alloy with standard structural sections.

Consider adding 15-20% weight contingency for connections, fasteners, and secondary structures.

``` ## How to Use This Tool This HTML tool provides a visual interface to adjust your seastead design parameters and estimate structural weights. Here's what it includes: 1. **Interactive Controls** - Adjust key dimensions using sliders 2. **Visual Representation** - See how changes affect the overall design 3. **Weight Estimation** - Calculate approximate structural weights based on marine aluminum construction 4. **Software Recommendations** - Open source tools for detailed design work ## Recommended Software for Detailed Design For actual structural design and detailed weight calculations, I recommend these open source tools: 1. **FreeCAD with Ship Design Workbench** - Perfect for parametric 3D modeling of marine structures with weight calculation capabilities 2. **OpenFOAM** - For hydrodynamic analysis of your NACA foil floats 3. **SALOME** - For structural analysis and meshing 4. **QCAD or LibreCAD** - For 2D construction drawings To use this tool, simply copy the entire HTML code into a file with a `.html` extension and open it in any web browser. You can adjust the sliders to explore different design options and see how they affect the estimated weight.
