The SEA.AI Watchkeeper series , designed to bring powerboats and sailboats a whole new level of security on the water. With advanced AI-powered object detection, ultra-wide 4K optics and optional thermal imaging technology, Watchkeeper offers an intelligent surveillance system that works 24/7 – even at high speeds and in challenging light and weather conditions.
The system identifies early on things that are often missed by both eyes, radar and AIS: drifting objects, buoys, unmarked boats and people in the water. The rapid analysis and clear alarms give the crew valuable seconds to make the right decisions and avoid dangerous situations.
The Watchkeeper series is available in several versions, from the entry-level model with low-light optics for day and twilight to more advanced models with long-range thermal imaging for full nighttime capability. Regardless of model, the system offers a wide field of view and fast response time that is suitable for both coastal tours and offshore passages.
The system integrates seamlessly with existing navigation screens thanks to support for most multifunction displays. No additional external screen is needed – the Watchkeeper app appears directly on your existing chartplotter and becomes a natural part of your navigation flow.
With its robust construction, smart alarm functions and high image quality, Watchkeeper acts as an extra, tireless lookout that always keeps an eye out – day or night. The series is designed for boaters who want to enhance both safety and the experience on board, without compromising on simplicity or performance.
Model overview - Watchkeeper series
SEA.AI Watchkeeper is available in several levels adapted to different types of boats, speed profiles and night vision needs. The series is modular and ranges from a simple day/twilight model to full-fledged thermal systems for night navigation with long range. Below is a summary of models and their functions. All models are then available for motor and sailboats and in black or white.

Watchkeeper Lite (Compact and cost-effective)
Designed for smaller boats, limited installation space, and users who want a simpler yet AI-powered surveillance system, Watchkeeper Lite combines optical and thermal imaging in a compact form factor, providing basic yet reliable detection of obstacles and hazards.
Watchkeeper 320 (Thermal – Entry-level model for night use)
The Watchkeeper 320 is the first thermal level in the series and provides basic night vision thanks to a 320x256 px thermal sensor with a 24° field of view for powerboats and 34° for sailboats. It is adapted for safe homecomings in the dark and at lower speeds, and provides a clear thermal image that makes it possible to detect small objects at shorter distances even in completely blacked-out environments. Perfect for smaller boats and for those who need a simple but reliable thermal solution.
Watchkeeper 640 (Thermal – Mid-range with longer range)
The Watchkeeper 640 is equipped with a higher resolution thermal sensor of 640×512 px with a 24° field of view for powerboats and 50° for sailboats. The improved night vision, higher detail and longer range mean that objects are visible earlier and clearer – even at higher cruising speeds. This model is ideal for boaters who often operate at dusk or in the dark and need a more advanced and responsive night vision solution.
Watchkeeper 1280 (Thermal – The flagship with maximum performance)
The Watchkeeper 1280 is the top model with a powerful 1280×512 px thermal sensor and an extra wide field of view of 48° for powerboats and 50° for sailboats. The system provides exceptionally good image quality and maximum detection capability on all types of floating objects, even at high speed and in difficult weather conditions. For offshore navigation, fast powerboats and demanding night environments, there is simply no better choice in the series.
