A naval architect makes sure a ship floats, stays upright, is strong enough, and goes where it should without wasting fuel or money. You will learn this in three stages. First comes the physics and math of floating bodies. Then come the tools and rules that employers hire for: hull modeling, stability calculations, class rules and USCG regulations. Last comes specialization and licensure. Most US jobs ask for a bachelor's degree in naval architecture and marine engineering, mechanical or ocean engineering. If you do not have one, this roadmap gives you the free knowledge, but be realistic: a d

Stage 1 of 3 · about 16 weeks
Understand why ships float and stay upright, and be able to do the basic hydrostatic and stability math by hand and in a spreadsheet.
Math and mechanics core
Every ship calculation is statics, calculus and fluid mechanics in disguise. If you can take moments about a point and integrate an area, you can do hydrostatics.
Fluid mechanics and Archimedes' principle
Buoyancy, pressure and resistance all come from fluid mechanics. Displacement equals weight for a floating ship, and this is the first thing you check in any design.
Ship geometry and hydrostatics
A hull is described by a lines plan (sections, waterlines, buttocks). From it you get displacement, LCB, KB, waterplane area, and the coefficients Cb, Cp, Cm and Cwp that compare hull forms.
Initial stability: GM and the righting arm
GM = KB + BM − KG tells you whether a ship returns upright. Getting this wrong sinks ships, so it is the heart of the job.
Excel and basic MATLAB or Python
Naval architects constantly build quick calculation sheets. Clean, checkable spreadsheets are a daily skill.
