Sailcargo Inc. has chosen Costa Rica as its base for the construction of Ceiba, a 148-foot, three-masted, square-topsail schooner that will be used for carbon-neutral cargo shipping.
The build combines traditional ship architecture and modern technology. She will be powered solely using the wind and a 100 percent electric engine, which will charge all of the ship’s own energy, functions as both a propulsion system and a generator whilst sailing. The engine will be combined with modern batteries and solar panels so that all auxiliary power is renewably sourced.
An advanced variable pitch propeller will convert kinetic energy into stored electrical energy to power the ship’s functions. Due to the high torque efficiency of electric engines, Ceiba’s engine will only need to be about 120 horsepower, which is easy half of what would be required for other engine designs.
Her three masts will provide sufficient sail area to sail in very light winds and enough flexibility and maneuverability for sail changes during heavy weather. Having sail area lower to the deck helps to stabilize the vessel, making her safer. Her three-masts also allow for flexibility when loading or discharging cargo, as her spars double as cranes.
Sailcargo chose Costa Rica for the project because of its commitment to carbon neutrality by 2021 and its favorable geographic position and business environment. Ceiba’s keel is to be made from four storm-fallen mountain tamarind trees uprooted by a hurricane in Upala. A reforestation project is underway to ensure that enough trees are planted on a regular basis to replace the materials used, off-setting the carbon footprint of the project and developing a sustainable system where more working vessels can be built entirely of lumber planted for the purpose.
