Harry Jr
About this gig
Your workboat or barge project should not be held back by unclear drawings, stability concerns, incomplete calculations, or USCG compliance requirements.
I provide professional naval architecture, USCG-compliant workboat design, barge design, hydrostatics, stability calculations, and marine engineering documentation for clients who need practical, technically sound results they can confidently use for their project.
Whether you are developing a workboat, deck barge, utility boat, tug, landing craft, pontoon, or commercial vessel, I can help turn your requirements into an engineering package.
You can get:
- Workboat & barge design
- USCG compliance support
- General Arrangement (GA) drawings
- Hydrostatic calculations
- Intact & damage stability calculations
- Trim, draft & displacement analysis
- Freeboard calculations
- Structural/strength calculations
- Lines plans & technical drawings
- 3D vessel modeling
- Professional calculation reports
Clients keep coming back because I communicate clearly, pay attention to technical details, deliver organized engineering work designed around the actual vessel.
Have a vessel concept, or a specific USCG requirement? Send me the details before ordering.
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.

I'm a Naval architecture engineer specializing in ship and boat hull design, deck layout, hydrostatics, and stability analysis. I calculate GZ curves, intact/damage stability, and build class-compliant stability booklets (IMO, SOLAS, ABS, DNV, Lloyd's, BV), not just 3D renders. From concept hull fairing to production-ready models, every deliverable is engineered to actually pass review, not just look finished. Boat builders, shipyards, and marine engineers hire me when the numbers have to hold up.
Message me with your vessel specs, I'll scope it accurately.

FAQ
Can you design a workboat or barge based on my existing drawings?
Yes. I can review your existing GA, dimensions, lines, loading conditions, and design requirements, then develop or refine the engineering package accordingly.
Can you provide USCG compliance support?
Yes. I can prepare design calculations and technical documentation aligned with applicable USCG requirements, including stability, freeboard, loading conditions, and vessel particulars. Final regulatory approval remains with the applicable authority.
What stability and hydrostatic calculations can you provide?
I can provide hydrostatics, displacement, draft, trim, KG/GM, righting-arm (GZ) curves, intact stability, and applicable damage-stability assessments based on the vessel and operating conditions.
