System voltage is more than just a technical spec—it’s the foundation of your onboard experience. From the universal compatibility of 12V to the 'silent-living' potential of 48V, we explore how choosing the right voltage creates a more composed, capable boat.

Modern onboard electrics are evolving quickly, and a question that comes up more and more is how far a boat can run in a DC-led way — and when AC naturally becomes part of the mix. In reality, most boats are a hybrid. Still, it’s useful to have two clear reference points, because they describe how a system is organised and the day-to-day “feel” that comes with it.

Offshore power isn’t about one perfect source - it’s about matching generation to the way a yacht actually consumes energy on passage. Learn a realistic, crew-tested mix that keeps the baseline covered day and night: continuous underway hydrogeneration, supportive solar and wind, and deliberate top-ups from alternator/generator when it suits the day.

Want the benefits of lithium without a major refit? Add a compact lithium bank alongside your existing system for more reliable power, easy charging upgrades, and a future-ready path to full lithium when you’re ready.

When your boat is moored in harbour, one of the most important functions of the shore mains connection is to safely and reliably charge your batteries while distributing AC power throughout the boat. That’s exactly what Cristec Shore Power Units are designed to do — combining multiple essential systems into a single, compact enclosure.

When planning a new trip or winter upgrades, it’s common to guess your yacht’s power needs based on past experience. However, a better way is to do a power audit. This shows exactly how much energy your yacht uses in 24 hours. With this info, you can size your batteries and charging system properly. Power audits also help you see how much energy your renewable sources will provide and how much extra charging you’ll need.

When Mike Hutchinson sailed from Falmouth on his Oyster 53, Distraction, he embarked on a full circumnavigation. After more than 31,000 nautical miles and crossing three oceans with the ARC+ and Oyster World Rally fleet, Mike and Distraction exemplify the power of careful preparation and smart equipment.

Yachting is about more than just reaching your destination - it’s about enjoying every mile along the way. For bluewater cruisers and coastal adventurers alike, comfort, reliability, and ease of use are the true essentials. We see first-hand how the right onboard systems can transform the cruising experience, whether you’re preparing for an Atlantic crossing or planning a summer of UK coastal exploration.

Ben and Alastair secured a last-minute spot in the ARC+ Transatlantic Rally. Their family-owned Bavaria Vision 46, initially for local cruising, required major upgrades for long-distance ocean sailing. With little time to prepare, they sought expert guidance from Osmotech and Advance Yacht Systems to create a self-sufficient, reliable setup for their Atlantic crossing and beyond.

The world of yacht power systems is evolving rapidly, driven by technological innovation, growing environmental consciousness together with a demand for smarter, quieter and greener solutions. As we enter 2025, yacht owners are looking at more sustainable power options to enhance their cruising experiences, whether navigating calm coastal waters or tackling more demanding long-distance journeys.

With extensive sailing experience, Hallberg-Rassy owner Richard Sharp will embark on the World ARC rally from St. Lucia this January. She will be more than prepared, not only with extensive provisioning and forward planning, but with a number of powerful pieces of equipment onboard, notably the Remoran hydrogenerator; a reliable partner in sustainable power.

When sailing away from shore, quickly and efficiently charging batteries is crucial to save fuel and reduce charging time. When planning for offshore sailing and long trips, improving your charging system can significantly cut the time needed to recharge batteries, making the process much easier.

Understanding the power consumption that your boat is likely to use daily can help you prepare for a long passage. By having a clear idea of your boat's energy needs, you can ensure that you have an adequate size battery bank on-board as well as sufficient power generation sources.

A good battery monitor is one of the most important devices you can invest in on-board your boat. Battery monitors are crucial to understanding the true state of charge of your batteries on a real-time basis and can provide you with real world benefits.

Mike Hutchinson, having completed the ARC+, plans to join the Oyster World Rally in his Oyster 53, “Distraction.” To reduce engine and generator use, he installed a Remoran Wave 3GS from Advance Yacht Systems in Falmouth. Mike chose Remoran because it’s a “beautifully made bit of kit” liking the looks of the unit compared to that of its competitors. “It looks so much nicer”, he says.
