Watchkeeper can be equipped with a total of three cameras.
Watchkeeper is an essential upgrade for greater safety on sailing yachts. The system acts as a digital co-pilot and supports sailors during the day and at dusk - even at night.

Safety on the water is a top priority - especially when visibility is limited or long passages have to be negotiated. With the Watchkeeper, the company Sea.AI is marketing a new series of camera systems designed to warn of collisions when mounted in the masthead. Sea.AI has already equipped ocean-going regatta boats with this technology under the old name Oscar. The Offshore One version, which was previously available for sports boats, cost well over 10,000 euros. The new Watchkeeper series starts at 5,000 euros, bringing it into the price range of conventional radar systems. Watchkeeper is available in two versions for motorboats and sailing boats. There are also versions with and without infrared technology, which is essential for night-time sailing. Here the price rises again to well over 5,000 euros. Watchkeeper is a digital co-pilot for motorboats and sailing yachts. The system promises consistent monitoring of the surroundings and helps boaters to make safer decisions when avoiding collisions. Whether on day trips, at dusk or in challenging visibility conditions, Watchkeeper is designed to ensure greater safety and a more relaxed driving experience by recognising other vessels and objects in the water and warning them in good time.

Versatile use on various waters

Depending on the version, the system is equipped with daylight infrared cameras that monitor the water surface in front of the bow even in the dark. The AI-supported analysis is designed to recognise and mark obstacles in real time and warn the crew. Watchkeeper was developed to adapt flexibly to different requirements. Boat owners can choose the configuration that best suits their vessel and their preferred sailing style. The system is suitable for both near-shore voyages and longer offshore passages. This versatility makes Watchkeeper an interesting option for different boat types and operational scenarios. The consistent monitoring of the environment is designed to help boaters make the right decisions even in challenging situations, making their time on the water safer and more enjoyable.

Different variants for day and night

The Watchkeeper is available in several versions. The first decision is for sailing or motorised boats. This is about the length of the cables. The motorboat version is 10 metres long. For sailing yachts, there are various lengths from 30 metres. The system can then be ordered in black or white. However, the major differences become apparent when choosing whether to sail by day and at dusk or day and night. In the latter version, an infrared camera is installed. Here again, you can choose between different resolutions: 320 x 256, 640 x 512 and 1024 x 640 pixels. The resolution determines how far in front of the bow the Watchkeeper can recognise boats and objects. At the lowest resolution, a buoy can be recognised by the system at a distance of 80 metres, a RIB at 350 metres and a yacht at 900 metres. At the highest resolution, these values shift to 170, 750 and 2000 metres for the same targets. However, this wider range of visibility also comes at a price. While the system without infrared camera costs 5,080 euros, the system with night vision and a resolution of 320 x 256 pixels costs 8,880 euros. With the highest resolution (and correspondingly the widest view), the Watchkeeper costs 25,580 euros.
