This is a project where traditional craftsmanship meets modern technology. This sailing cargo ship will mainly be using the wind to transport their cargo. There will be a high tech fully electric propulsion system on board. During sailing by the wind, the batteries will be charged by controlable pitch propellers that are driven by the speed of the boat. The generated power stored in the batteries will be used when there is no (favourable) wind and for manoeuvring in harbours.

The dedicated team behind this project has setup a completely a new 'eco' shipyard 'AstilleroVerde' in the rural community of Punta Morales, Costa Rica. Their preferred building method using wood is based on a very clear mindset to build in a sustainable way. Costa Rica’s strict forestry laws, along with Sailcargo's ethical standards and their sustainable partner network, ensure that all lumber is sustainably harvested. Next to their sustainable timber sourcing practices they have ongoing tree planting and reforestation programs. These programs help offset carbon emissions of the project, reforest exploited land and supply shipbuilding lumber for future generations. The AstilleroVerde Shipyard is one of the biggest employers in the area.

Sigma Plus Associates from Switzerland is developing the electic regenerative system based on experiences with Schooner Opal from North Sailing in Iceland.

The mission of SAILCARGO INC:
"We will build and operate a cargo sailing vessel by synthesizing old-world ship building techniques with avant-garde energy and propulsion systems design. Our vision is to create a prosperous regenerative model that meets the ecological, ethical, and economic requirements of our rapidly changing world. Our objective as Costa Rica's Flagship is to demonstrate that a carbon neutral shipping company can not only be financially competitive, but can inspire change and educate."

Currently the construction of the vessel is in full swing in Costa Rica. You can be part of this project and even become a shareholder of the ship. There is lot's of information, blogs, photos, videos available through the channels of Sailcargo if you like to follow this project.


Below you can see 2 full interactive 3D models. The first one gives an impression of the finished vessel. The last one gives a rough idea of the primary wooden structure.
You can rotate and zoom to have a good look at the model. You may need to practice a bit to move around the model the way you want. In the lower right corner of the window showing the model, has some options and settings that can be changed. For example go to full screen and you can set the 'navigation' to 'first person', this way you can use your arrows on your keyboard. If you have a 'VR' headset, you should be able to use this as well. I hope you enjoy it.
