The innovative and remote-controlled rescue robot FASTY allows you to quickly and safely save people from drowning. FASTY enables initial rescue operations while the rescue team is getting ready. FASTY sometimes even does the rescue without the rescuers having to enter the water.

The Maren FASTY Lifeguard Robot. A water rescue multi-talent, when it becomes too dangerous for humans

FASTY enables safe and very fast rescue of drowning persons. The self-propelled water rescue robot reaches endangered persons at up to 15 km/h, i.e. many times faster than a lifeguard or a boat or ship. With the Maren FASTY, there is a high chance of water rescue within the golden rescue time. With FASTY, the chances of a successful rescue within this required rescue time increase. With FASTY, the rescue time can ideally be reduced from over 10 minutes to about 2 minutes.
The conditions in open and stormy waters are extremely dangerous not only for the victims but also for the rescue forces. By using FASTY, you accordingly also increase the safety of your rescue team and save important resources that can be used for the search at multiple locations. FASTY is not only safe for the rescuers but also for the victims. Internal propellers and padding prevent injury to those being rescued. Rescuers using the water rescue robot can operate it either manually or remotely. FASTY helps to avoid risks and/or accidents during rescue work.
FASTY is easy to operate. The control with remote control is easy to learn and intuitive. After a few minutes, FASTY can be operated without any problems. No expensive training is required. FASTY is extremely robust and constructed of fiberglass and can be thrown into the water from a 20-meter-high place like a bridge or from boats. This is especially critical if you do not have direct access to water. The FASTY will bring your victim to a place where you have safe access to the injured person.
Normal and ordinary lifebuoys require you to approach the casualties with your boat. Lifebuoys must be thrown correctly and with pinpoint accuracy and appropriate distance in order to actually help drowning victims. The entire process, from locating to actual rescue, can take much more time than is actually available for the rescue. With FASTY, your boat does not have to approach the victim, only the remotely operated rescue vehicle. And exactly this circumstance saves a lot of time. With a FASTY you have the possibility to rescue up to 2 people at once. With a long deployment time of up to 60 minutes, you can perform several missions in a row or transport rescue equipment to the victims.
Due to its design with 2 powerful drives, the FASTY can also be used in bad or stormy weather without any problems. FASTY is used where you do not want to send your rescue team into the water at first. FASTY is equipped to withstand larger waves due to its larger dimensions and anti-tip construction. Avoiding tipping over in waves saves valuable rescue time. It can also be used in slow-flowing rivers or in floodwater. The drives of the FASTY are equipped and constructed in such a way that flotsam or seaweed can be removed in an easy and safe way, should a blockage occur.
The FASTY water rescue robot transmits important information for the rescue mission to the remote control. For example, the charge status of the battery or whether overheating is imminent. This allows you to cleanly control the progress of the rescue at any time. FASTY can be further upgraded. For example, cameras or additional lights can be carried, or an intercom system. If the electronics should fail or there is no connection to the remote control, FASTY can also be controlled manually.
At the scene of an incident, every second counts. For the victim as well as for the rescuers and also for the potential victims. The equipment that supports this rescue must therefore be reliable and quickly ready for use. The focus should be on the rescue and rescue tactics, not on the equipment setup. FASTY is designed so that it can be used quickly by any rescuer at the scene, even without explanation. FASTY can be operated without explanation and is therefore also suitable for use in hotels, beach resorts, and on yachts.
FASTY lifebuoys are designed for low operating costs. On the one hand, the FASTY offers a very high mechanical quality combined with a very long service life even in tough use. It is made of materials as that have been successfully used in sea rescue for years. The availability of FASTY spare parts and corresponding service & warranty plans further reduce your operating costs. Components of the highest and tested quality are installed, such as state-of-the-art and reliable battery technology. So that rescuers do not experience any surprises when it counts.
FASTY is not only used to rescue drowning victims. FASTY is also happy to provide shuttle services for divers who have drifted from the boat. FASTY also delivers material to dive sites if you don’t want to take the big boat off the anchor. Even if your victim is unresponsive, the Fasty will bring your divers to the scene. So FASTY partly takes over tasks of a normal scooter, but this remote controlled

Water rescue drones can reach people in distress quickly and deliver flotation aids or rescue equipment—without putting a lifeguard at risk. Especially in stronger currents, cold water, or hard-to-reach areas, they offer a life-saving alternative. Even at night or in poor weather conditions, drones enable fast and safe initial response while human rescuers prepare or follow up.
Equipped with cameras and sensors, water rescue drones provide critical real-time visuals for situational assessment—such as during ship accidents, floods, or search operations. With additional aerial or thermal imaging, they help locate missing persons and identify hazards early. They also allow for full documentation of rescue operations for post-mission analysis or legal purposes.
Rescue drones can assist divers on their way to or from the mission site—especially over longer distances or when fatigue sets in. Divers can conserve energy by being towed, and the drone can also support their return after a dive. During underwater missions, the drone can remain nearby, ready to assist or respond in case of emergency.
Drones are well-suited for targeted delivery of supplies across water. They can carry medical equipment like medications, or bandages to otherwise inaccessible locations. In flood situations, they can transport essentials such as food, drinking water, or communication tools. They’re also ideal for delivering tools or spare parts to boats, platforms, or remote responders.

The unmanned mini-ROV SAGA-PRO can dive to a depth of 300 meters. ROV means Remotely Operated Vehicle, i.e. a remotely controlled underwater vehicle. These ROVs are mostly available as cabled underwater vehicles. Such professional underwater vehicles and underwater drones are mainly used in the fields of industry, research, and science as well as by the police, fire department, and military.
SAGA-PRO enables instant image transmission from the water with its high-resolution front and rear cameras and lighting systems that can move together with the camera. SAGA-PRO can be operated without a time limit as the power is supplied by cable. With the help of the robotic arm and various grippers, it can transport the detected objects from the underwater world to the surface. SAGA-PRO can perform appropriate search and detection activities even in waters without visibility thanks to the advanced sonar units that can be attached to it.
SAGA-PRO offers ease of operation with its high maneuverability and advanced autopilot features and can accelerate up to 3 knots. The system, which additionally has lightweight and easy-to-transport equipment, allows operations to be conducted even from a Zodiac boat. The SAGA-PRO model, which has a higher payload capacity compared to SAGA, offers the possibility of integrating additional equipment such as a metal detector, underwater location system, and 360-degree dome camera, in addition to the usual temperature, depth, and compass sensors.
