Collisions between speedboats and marine life or swimmers are a growing concern, causing preventable harm to both ecosystems and people. While existing solutions like alarms and sonar displays help operators spot hazards, they rely entirely on human reaction time—a critical gap when seconds matter. One way to address this could be an automated system that physically prevents collisions by cutting engine power when threats are detected.

How It Would Work

The system would combine multiple sensors (sonar for underwater detection, infrared for surface scanning) with direct motor control. When any object enters a predefined danger zone (e.g., 5 feet around the boat), the engine would automatically disengage, allowing momentum to carry the boat without further acceleration into the obstacle. Key features could include:

• Multi-sensor validation to reduce false alarms (e.g., ignoring floating debris but detecting manatees)
• An emergency override for situations where stopping would create greater danger
• Geofencing to adjust sensitivity in high-traffic areas versus wildlife zones

Why It Matters

Unlike existing warning systems, this approach removes human latency from the safety equation. For example:

• Marine conservation: Automatic protection could reduce manatee deaths by ~25% in collision-prone areas like Florida canals.
• Boaters would benefit from reduced liability and potential insurance discounts.
• Tour operators could market eco-conscious safety as a competitive edge.

Regulators might incentivize adoption in protected zones, creating a natural testing ground before broader rollout.

Getting Started

A practical first step could be developing a retrofit kit that attaches to existing outboard motors, connecting to the engine kill switch. Pilot testing with conservation groups in high-risk areas (using animal dummies) could refine detection algorithms before approaching boat manufacturers for OEM integration. Early versions might focus on specific high-impact scenarios, like preventing manatee strikes in shallow waters, before expanding to general use.
