About this gig

Is your vessel missing reliable hydrostatic or intact/damage stability calculations? Are you struggling with displacement, drafts, trim, GM, GZ/KN curves, or stability documentation?


I prepare professional hydrostatic, intact stability and damage stability calculations for ships, boats, yachts, barges, workboats and offshore vessels using your vessel data and project requirements.


You can get:

  • Hydrostatic calculations and principal particulars
  • Displacement, drafts and trim analysis
  • GM, GZ/righting-arm and KN curves
  • Intact stability assessment
  • Damage stability and loading-case analysis
  • Stability tables, curves and clear reports


My focus is not simply producing numbersit is delivering organized results useful for design review, documentation and decision-making.


Clients keep coming back because I pay attention to vessel details, check calculation logic and communicate clearly instead of delivering generic files.


Have vessel dimensions, a lines plan, 3D model, loading conditions or previous calculations? Send them over. Ill review what you have and identify what is needed.


Message me today with your vessel details and requirements. Lets turn your stability problem into a calcs.

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.
