With its Virtual Anchor packs, BlueNav introduces a positioning solution based on electric propulsion, presented at the Nice Boating Tomorrow show from March 19 to 22, 2026.
Anchorless positioning for intermediate units
Maintaining position remains a common need, whether for fishing, diving or certain professional operations.
Existing solutions fall into two categories. On the one hand, electric trolling motors, limited to small units and sheltered conditions. On the other, thermal dynamic positioning systems are heavier, with higher fuel consumption and associated nuisances.
Between these two segments, boats from 7 to 22 meters have few alternatives. BlueNav has positioned itself in this niche with an electric solution capable of maintaining power for several hours.
Architecture based on controlled electric propulsion
The principle is based on an electric outboard motor coupled to an automated steering system. The boat continuously adjusts its position according to wind and current.
The system is based on GPS positioning and automatic corrections. The whole system maintains a defined zone without the need for a physical anchor. Control is via a 3D joystick, with a logic similar to dynamic positioning systems, but adapted to electric motorization.
Integrated packages to simplify installation
Virtual Anchor Packs are available in complete configurations. Each package includes an 8 kW or 11 kW electric motor, a lithium IonBase battery system and associated power electronics. Power capacities are based on one or two 3.4 kWh batteries. Standby time is around 8 hours, depending on conditions.
The package also incorporates the assisted navigation functions developed by BlueNav, with maneuvering and positioning aids. Two versions are available. The 8 kW pack targets units from 1 to 7 tons. The 11 kW pack is aimed at boats of up to 10 tons or requiring a higher energy reserve.
Suitable for use in restricted areas
The development of this type of solution is taking place against a backdrop of changing practices. Some areas limit or prohibit anchoring to preserve the seabed.
In Nice, the creation of a marine protected area in the Baie des Anges illustrates this trend. Anchorless positioning becomes an operational alternative. The absence of contact with the seabed avoids the damage caused by anchors and chains, particularly to seagrass beds.
Real-life demonstration at the show
The technology is presented on a demonstration boat developed with AtlantiCraft, a BlackPearl 7 equipped with the BlueNav system.
The tests enable us to observe how the boat behaves when held in position, and how responsive the system is to variations in wind and current. This type of demonstration remains central to the evaluation of these solutions, which are still in the process of being launched on the yachting and light professional craft markets.
