TankerProa Sailing For most of the trans-ocean voyage the vessel will be propelled in the down wind direction. As the vessel approaches the destination anchoring location the trade winds may not be oriented for pure downwind sailing , this is when the capabilities to sail on a broad reach, and to perform tacking maneuvers can be utilized to get closer to the destination port.
After de-coupling from the tanker vessel the space frame sails to the local anchoring location associated with the destination port.

Ballast Water Elimination Tanker vessels that have delivered their liquid cargo, are significantly more unstable against rolling than when fully loaded.
To offset this problem they take on ballast water at the port where they have made their delivery in order to stabilize the vessel for the return trip.

The use of the space frame for this vessel provides the stability required without the need for ballast water, and also eliminates the need for ballast water sterilization equipment.

CO2 Emission Reductions Reduction of diesel fuel usage from full power to diesel engine idling with in-port diesel fuel, reduces amount of fuel used when under pure sail power and consequently CO2 emissions.

Renewable energy generated by the TankerProa used to control both sails,
as well as rudder and dagger board rotations.
