If you’re considering living aboard while continuing to do knowledge work — not switching careers to full-time maintenance — this guide helps you avoid the two mistakes that cost the most money and time.
Electric Displacement Speed on Large Hulls
A physics-grounded analysis of electric propulsion limits on large displacement hulls, calibrated against real on-water GPS data from a ~24-ton vessel. No hype, no despair — just honest bounds. Includes the full Markdown write-up (ElectricDispSpeed.md), a formatted PDF (arpeggio-calc-report.pdf), and supporting figures, packaged as a single ZIP.
