I will do stability analysis, gz curves and hydrostatics for your boat or usv
Mohammad Arham
About this gig
Is your boat or USV stable enough? I run proper intact stability analysis so you know before you build or launch.
WHAT YOU GET:
- Hydrostatic tables: displacement, draft, trim, LCB, LCF, KB, BM, GM, TPC
- GZ (righting arm) curves up to 90 degrees heel
- GM and range of stability for each loading condition
- Check against common intact stability criteria (IMO/ISO style)
- Weight and centre of gravity estimate from your CAD or parts list
- Clear PDF report with plots and plain-language conclusions
IDEAL FOR: USVs, drones, RC and model boats, catamarans, small workboats, student and research projects.
RECENT WORK:
- 1 m Series 64 catamaran: GZ curves comparing two hull shell weights (GZmax 0.16 m at 20 deg, GMt 0.56 m)
- WAM-V 16 catamaran: hydrostatics from lightship to full load, drafts matched to published values
EXTRA: CFD resistance study available as an add-on.
Please message me before ordering with your hull geometry (CAD, lines plan or dimensions) and weights.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

Hi, I'm Arham, a naval architecture and mechanical design engineer.
I design and check small boats, USVs and catamarans: hull sizing, hydrostatics, intact stability (GZ curves), resistance and power prediction, and CFD/FEA studies. I build accurate Rhino, SolidWorks and Creo models ready for manufacturing, 3D printing or simulation.
Recent work: a 1.4 m survey USV catamaran and a 204-part WAM-V 16 model accurate to 0.1% of spec.
Clear reports, real engineering, on-time delivery. Message me before ordering!

FAQ
What do you need from me to start?
Your hull shape (CAD file such as STEP/IGES/3DM, a lines plan, or main dimensions), the weights of the main components and where they sit, and the loading conditions you care about.
Can you check a boat that is already built?
Yes. With measured dimensions, photos and weights I can rebuild the hull and check its stability, then suggest where to move ballast or equipment if it is tender.
