El largo viaje, Moitessier

On board a sailboat, especially when sailing in remote areas, it will often be necessary to perform repairs and maintenance on many vital systems, such as the electrical system, the engine, the rigging, the galley, etc.

Nigel Calder’s “Boatowner’s Mechanical and Electrical Manual” is the most comprehensive and detailed manual I know of, and it has helped me maintain and improve many pieces of equipment on board. It’s an essential book to have readily available on any sailboat.
