Chemistry 730 – 3D Empty Hull Geometry Model (STEP + PDF)

Accurate hull geometry for builders and designers who want a clean, professional starting point.

Designed by Manufacture Arnout

20 years of manufacturing and welding experience.

This model is built from real fabrication knowledge — not academic theory.

Design intent & operating envelope

The HM730 hull was designed primarily for inland and in‑water use, with an emphasis on:

• Low planing speed
• Good stability
• Low wake when operating in non‑planing conditions

The hull can be taken offshore on calm days, but it is not designed for absolute top speeds or rough offshore conditions.

This design prioritizes efficiency, control, and reduced wake over high‑speed performance in heavy seas.

What this product is

This product contains the 3D hull geometry only of the HM730.

It is intended as a base model for:

• Boat designers
• Metal boat builders
• DIY projects
• Anyone who wants to develop their own structure and layout

You receive a clean, usable hull shape that you can adapt to your own design and construction method.

What’s included

• STEP (.stp) file – hull plates geometry
• PDF file – reference views and window plans

File sizes

• STEP: ~6 MB
• PDF: ~5 MB

What’s NOT included

To avoid confusion, this product does not include:

• Construction drawings
• Structural framing or internal layout
• Scantlings or engineering calculations
• Welding instructions
• Performance, stability, or seaworthiness guarantees

You are expected to design and engineer the structure yourself.

Who this is for

This is for you if:

• You want a solid hull geometry as a starting point
• You understand basic boat design or construction
• You want freedom to design your own structure and layout

This is NOT for you if:

• You expect a ready-to-build kit
• You want step-by-step construction plans
• You have no intention of doing your own engineering or design work

Disclaimer

This 3D model is provided for design reference purposes only.

The designer is not responsible for:

• Construction errors
• Structural failure
• Injury, damage, or death
• Vessel performance, stability, or seaworthiness

By purchasing this product, you accept full responsibility for all design, engineering, and construction decisions.
