Lift Ocean Develops Retrofit Hydrofoil System for Conventional Boats
The ONE system enables existing boat hulls to achieve efficiency gains through hydrofoil technology.
1Retrofitting Existing Marine Vessels
Norwegian firm Lift Ocean is developing ONE, a hydrofoil system designed to upgrade conventional boats without requiring a new hull. Unlike typical hydrofoil vessels that demand specialized construction, this system integrates into existing designs. It offers a path to improved efficiency for boat owners who wish to retain their current vessels.
2Mechanical Wing Configuration
The hardware layout features one foil assembly at the bow and two at the stern, positioned around a single outboard motor. Each assembly utilizes a movable underwater wing attached to a vertical mast. As the boat accelerates, these wings generate lift, effectively raising the entire hull above the water to reduce drag.
3Active Control and Stability
Maintaining stability while foiling is managed by an active control system that automatically adjusts wing angles. This technology handles ride height and banked turns, allowing the driver to operate the boat using standard steering and throttle inputs. By automating balance, the system removes the need for operators to learn complex manual piloting.
4Retractable Design for Maintenance
The system includes retractable wings, which allow the boat to operate in a conventional planing mode when necessary. This feature simplifies maintenance, reduces the accumulation of marine growth on the foils, and ensures the vessel remains compatible with standard boat trailers. These practical design choices address the realities of long-term boat ownership.
5Propulsion and Engine Integration
ONE is compatible with both gasoline and electric outboard motors, ensuring users are not forced to change their energy source. An automatic engine lift bracket adjusts the motor vertically to keep the propeller submerged as the hull rises. This mechanical synchronization ensures that propulsion remains consistent throughout the entire transition to flight.
6Projected Efficiency Gains
Lift Ocean reports that testing indicates a roughly 50 percent reduction in fuel consumption for equipped vessels. While the company notes that actual results vary depending on the specific boat model, the potential for energy savings is significant. This approach shifts the focus toward optimizing how a boat travels through the water.
7Industry Availability Timeline
The system is currently limited to boat manufacturers and fleet operators rather than individual retail consumers. Shipping for these initial units is expected to begin in 2027. This B2B focus ensures that the integration process is handled by professionals capable of managing the necessary structural modifications required for different vessel types.
8Engineering Realities of Integration
CEO Petter Mørland Pedersen emphasizes that while the system is modular, it is not a universally effortless bolt-on solution. Manufacturers must perform specific integration work based on the unique structure and proportions of each vessel. This realistic assessment of engineering requirements adds credibility to the company's long-term product development strategy.
