Marinanhelmi is a Finnish boating industry expert. We operate from Southwest Finland and our market area covers the whole of Finland. We have a decade of experience with both motor and sailing boats. Our commitment to high-quality and professional service means that we bring only the best to Finnish waters.
That’s why we proudly represent SEA.AI products, the world’s leading AI-based safety system, which brings true peace of mind to your boating experience.
Every mariner's greatest concern is the invisible threat. Traditional navigation systems, such as radar and AIS, are invaluable tools, but they have their limitations. They do not always detect small, poorly reflecting, or untransmitted moving objects. The human eye, on the other hand, tires, and its ability to perceive weakens in darkness, fog, or glare from the sun. SEA.AI offers a revolutionary solution to this safety gap.
SEA.AI is not just a camera; it is your vessel's intelligent and tireless lookout, monitoring your surroundings 24/7. By combining cutting-edge camera technology and artificial intelligence, SEA.AI detects and classifies objects that conventional systems may overlook. These include vessels without an AIS transmitter, drifting containers, garbage rafts, buoys, rubber boats, kayaks, and especially individuals who have fallen into the water. By providing you with complete situational awareness, SEA.AI not only reduces the risk of collisions but also gives you peace of mind to fully enjoy your time on the water.

For a powerboater, speed and freedom are at the heart of the experience, but they also bring with them the responsibility and the need for quick reactions. At high speeds, on busy waterways, or when reaching an unfamiliar harbor as dusk falls, perfect situational awareness is the foundation of safety. The Watchkeeper is designed to meet these challenges. It is more than a safety device; it is a tool that allows you to enjoy your boat's performance without compromising on safety.
watcHkeeper, SAILBOAT | 5630- 31360€ |
Sail with peace of mind, day and night. The Watchkeeper is your tireless watchkeeping companion who never sleeps. It frees you from the constant pressure of lookout duty and allows you to focus on what truly matters – the joy of sailing. Whether you are crossing an ocean or navigating a busy coastline, the Watchkeeper watches over you and alerts you so you can sail with confidence.
Ultra-wide 4K resolution provides a complete image
At the heart of Watchkeeper is its exceptional optics. The system's 4K low-light camera (resolution 3840×2160 pixels) and HDR technology produce a crystal-clear image, but its true advantage lies in the ultra-wide 130-degree field of view. Unlike traditional narrow-view cameras, Watchkeeper gives you a broad picture of the space unfolding in front of the vessel. At high speeds, this is critical, as threats can come from the side—whether it's another vessel, a jet ski, or an unexpected buoy. A wider view means more time to detect, assess, and respond, which directly correlates to increased safety. In daylight, the system can detect, for example, a buoy at 65 meters, a rubber boat at 350 meters, and another leisure boat at up to 900 meters away.
Tireless guardian around the clock
Conditions on the water can change rapidly. Bright sunlight, dusk, or complete darkness pose challenges to human eyesight. The Watchkeeper series offers models equipped with advanced thermal camera technology, ensuring true 24/7 surveillance. The thermal camera does not require visible light; it "sees" the thermal radiation of objects. This allows it to cut through darkness, sun glare, and even light fog, revealing the thermal signatures of other vessels, people, and obstacles when the naked eye cannot see anything.
Seamless integration and ease of use
High technology doesn't have to be complicated. Watchkeeper is designed to integrate seamlessly with your boat's existing systems. It is compatible with all leading multi-function display (MFD) manufacturers, and its images and alerts can be managed and viewed from any vessel using iOS or Android devices. This modern and flexible user interface ensures that critical safety information is always easily accessible. The result is worry-free travel. Watchkeeper is not just a safety device; it is a source of peace of mind that allows you, your family, and friends to relax and fully enjoy the boating experience.

It gives you the freedom and peace of mind to enjoy the journey, whether you are alone or with family.
AI-enhanced vision – even in the dark
The AI-based system of Watchkeeper has been trained to identify objects that can easily go unnoticed by radar, AIS, or a tired human eye. It distinguishes fishing net buoys, drifting debris, unlit small boats, and even icebergs from the water, immediately alerting you to potential dangers. Watchkeeper becomes especially invaluable at night. Its advanced thermal camera technology "sees" in the dark and reveals the thermal signatures of objects, enabling safe navigation even in challenging conditions. In a critical "man overboard" situation, the system's ability to detect a person in the water through thermal sensing can be vital.
Designed for sailors
We understand that sailors value simplicity and reliability. Watchkeeper is designed to be lightweight and easy to install, seamlessly integrating with your boat's existing multifunction displays. The system can be controlled and monitored from a tablet or smartphone from anywhere on the boat, whether you are at the helm or resting in the saloon. Three different alert modes (harbor, coastal, and open sea) allow the system to be customized for each sailing situation. Watchkeeper not only enhances safety but also improves the overall sailing experience. It gives you the confidence and peace to truly enjoy every moment at sea.
