This design concept involves a solar electric trawler for one family, equipped with active paravane stabilizers. These stabilizers resemble small airplanes or gliders and use tail fins to adjust their angle, altering the pull on the outriggers to stabilize the trawler. The goal is to achieve a stable ride at low speeds (around 4-5 knots) while leveraging solar power to eliminate fuel costs.
Yes, there are underwater-rated actuators designed for marine applications. These actuators can be repurposed or custom-built to control the tail fins of the gliders. They must be durable, corrosion-resistant, and capable of operating in saltwater environments.
The size of the actuators would depend on the force required to stabilize the trawler and the speed of the boat. For a 4-knot trawler, relatively small actuators (e.g., 10-20 cm in diameter) could suffice, assuming the gliders are lightweight and the forces are manageable.
Custom underwater actuators can range from $200 to $1,000 per unit, depending on size, material, and complexity. Off-the-shelf marine actuators may also be available for a lower cost, though they may need modification for this application.
The force required would depend on the size of the gliders, the stroke of the tail fins, and the speed of the trawler. Initial estimates suggest that each glider could generate between 5-20 pounds of force, which would be sufficient to stabilize the trawler without requiring excessive power.
The size of the gliders would depend on the force they need to generate and their aerodynamic efficiency. For a trawler sailing at 4 knots, gliders with a wingspan of 1-2 meters and a length of 2-3 meters could be sufficient. These dimensions would allow for manageable actuation while providing adequate stabilization.
At 4 knots, the power required to pull the gliders through the water would depend on their drag and the force they need to generate. Assuming each glider generates 10 pounds of force and operates at a speed of 4 knots (approximately 3.47 m/s), the power required per glider would be around 10-20 watts. For two gliders, this would total 20-40 watts. Factoring in inefficiencies and the cost of solar panels, this would be a manageable power draw for a solar electric trawler.
Yes, this design is plausible. By combining solar power, lightweight gliders, and underwater actuators, the trawler could achieve a stable ride at low speeds while eliminating fuel costs. The use of sensor feedback and an IMU-based control system would allow for real-time adjustments to the gliders' angles and force output, ensuring optimal stabilization.
The lines connecting the gliders to the trawler would need to carry power, data, and control signals. High-strength, lightweight cables (e.g., Dyneema or Kevlar) would be ideal for this purpose. On the trawler, an IMU and control software would interpret data from the sensors on the gliders to adjust their position and force output accordingly.
Testing the concept with an existing boat is highly recommended to validate the feasibility of the design. This would allow you to refine the system, test the actuators, and gather data on the gliders' performance in real-world conditions before committing to the construction of the solar electric trawler.
