Project Sea-Volt: Converting a Sailboat to Electric

The journey of ripping out a diesel engine and embracing a silent, sustainable electric propulsion system.

The heart of my classic C&C 35 sailboat was a noisy, smelly, and unreliable diesel engine. The decision to convert to electric was driven by a desire for silence, simplicity, and sustainability. This project, "Sea-Volt," is a complete documentation of that transformation. It's more than just an engine swap; it's a complete systems overhaul. This series chronicles the entire process, from the initial energy audit and battery bank calculations to the physical removal of the old engine, building the custom motor mount, and wiring the new electric motor. We'll dive into the nitty-gritty of battery chemistry (LiFePO4 vs. lead-acid), solar charging integration, and the joy of sailing silently out of the harbor for the first time. This is a story of engineering, problem-solving, and redefining what a sailboat can be.
