The Future of Life on the Water
The most transformative advances in leisure boat technology since steam replaced sail.
For more than a century…
leisurely life on the water presumed boats would be built around internal combustion engines and piloted by a person at the helm competent in a variety of skills not the least of which was engine maintenance and repair.

Hybrid Yacht Propulsion & Electrical Innovations
NO GENSET. NO RUDDER. NO FULL-TIME CREW.
Sobe Sunset is a diesel-electric hybrid boat: a parallel hybrid marine drive pairs highly efficient diesel engines with electric motors fed by a 750V DC yacht battery system of LiFePO4 lithium cells.
The marine lithium batteries charge from the diesels, an 11 kW yacht solar array, a shore power charger at the dock and even tidal currents. And this is only one way the prototype vessel, Sobe Sunset, is a huge leap forward. Other innovations include:
- HVAC system (heating, ventilating and air conditioning) is solar-powered variable-speed
- Helm side-stick controls
- Differential thrusters replace a conventional rudder system
- A custom marine HMI on vessel monitoring touchscreens analyzes performance data onboard; remote boat monitoring sends it ashore by satellite
- Operational commands can be sent back from an onshore operations center via satellite
The result is life on the water that is simpler, safer, less worrisome, less expensive, and less dependent on an onboard mechanically skilled crew.

The propulsion system of the prototype Sobe Sunset is a parallel diesel-electric hybrid. When cruising at up to eight knots, the propulsion — including forward and reverse operation — is all electric; when up to 11 knots, one of two diesel engines comes online; and when up to 14 knots both diesels are employed.
Any time a diesel is running it is also charging the lithium batteries through two generators, which are part of the onboard electric motors attached to the diesels. The lithium batteries are also charged through optional solar collectors and, at anchor, by means of tidal currents.
Sobe Sunset has no rudders. Nor does it have a traditional wheel or helm. It has made extraordinary improvements over both these aged maneuver mechanicals.
The main problem with rudders is that they are a principal source of drag. They add to drag even when aligned with the keel. In a turn, to some extent they add drag so that the bow is brought to a new heading.
Sobe Sunset has eliminated rudders and induces banking more in line with aircraft than seacraft. Sobe Sunset turns are affected by engine thrust differential. For a turn, one engine thrusts more than the other.
Cooling, heating and de-humidification for the interior environments onboard large vessels consume the most energy among all the vessels powered systems. Current systems simply turn on and off to meet air conditioning demands, wasting energy and drawing incredible power from the ships electrical system.
Our HVAC solution is a highly efficient digital scroll compressor controlled by variable frequency drive combined with temperature sensors throughout the vessel. A sophisticated control system regulates the compressor speed to meet the heating/cooling demands of the vessel’s various internal spaces as efficiently as possible, reserving more energy for travel and the other electrical systems onboard.
Our spud pole anchoring system is significantly safer and easier for an operator to deploy and retrieve than a conventional weighted anchor on a chain and allows the vessel to hold its position in a tight anchorage or in a channel.
The spud pole is raised and lowered hydraulically using seawater pumps, typically used for fire extinguishing and water extraction.
While anchored, our hybrid propulsion system can act as a generator using tidal flow to spin the propellers and charge the onboard batteries, supplementing the solar power generation and paving the way for self-sufficient boats.
The top of the spud pole chamber can also serve as an awning for shade on the bow.
Highly Intelligent
Remote Guidance & Operation
predictive maintenance
Our solutions are centered around making semi-autonomous, singlehanded operation a reality for large, complex boats. Our vessel-wide yacht automation system of electric components, sensors, and controllers makes it possible for a crew of engineers to operate remotely while increasing safety and comfort for those onboard. Its boat alarm system sends text alerts: engine alarm monitoring, bilge and high water alarms reach the crew and the operations center by SMS.
Remote monitoring and operation of the vessel’s major navigation, engineering, and maintenance functions greatly reduces the need for onboard staff, resulting in a more intimate travel experience. The same systems used for remote monitoring are used to improve preventative maintenance capabilities, minimizing potential downtime due to unexpected maintenance. Everything aboard was engineered and installed by our own yacht electricians in Miami: a marine electrical contractor team for South Florida covering yacht electrical refits, electric propulsion conversion, marine lithium battery installation, 24V marine battery upgrades, marine solar, shore power conversion, custom yacht monitoring systems and boat alarm systems with text alerts.
