Water Rescue Training with SARA in Lydney

At Crest Marine Services, safety on and around the water is at the heart of what we do. Last week, I had the opportunity to join a day’s water rescue training in Lydney with the Severn Area Rescue Association (SARA) an invaluable experience that deepened both my skills and respect for those who dedicate their time to saving lives.

The course took place under blue skies and bright sunshine, with my fellow trainees being a team from the Environment Agency. While the conditions were calm, the training scenarios were designed to prepare us for the far more challenging situations that real incidents can bring.

We began the day with discussions on how to approach a water rescue, covering scene assessment, hazard awareness, and coordination with other emergency services. A key focus was on personal protective equipment, including the correct selection, inspection, and use of lifejackets and buoyancy aids, ensuring both rescuers and casualties remain as safe as possible during an incident.

First aid was also a central part of the morning, in many real-life rescues pulling someone from the water is only the start. We explored best practice for first responders and how to provide immediate care until further help arrives.

The afternoon moved into practical training, putting the theory into action with the deployment of lifebuoys, throwlines, and reach poles. These hands-on exercises allowed us to test techniques, work under time pressure, and gain confidence in using specialist rescue equipment effectively.

Preparedness doesn’t stop when the training ends. My own van carries a rescue throwline ready for immediate use in an emergency part of our ongoing commitment to being able to assist quickly and effectively should the unexpected happen.

It was an excellent day of learning, made even better by the expertise and professionalism of the SARA trainers. Whether it’s responding to emergencies, maintaining safe operations, or simply being prepared for the unexpected, training like this ensures we’re ready to help keep people safe on the water.

A big thank you to the SARA team for their dedication and knowledge and to the Environment Agency staff for being great training partners.

Powering Up for a 10 year Circumnavigation

At Crest Marine Services, we pride ourselves on delivering reliable, safe, and creative solutions for complex electrical issues afloat. One of our recent callouts came from the skipper of Shadowfax, a yacht preparing for a ten-year circumnavigation, and just three days from departure.

The problem? The vessel’s inverter wouldn’t run the calorifier’s immersion heater. The setup worked fine from shore power and the generator, but the inverter refused to cooperate, despite the live being properly connected. It was clear this wasn’t a basic fault.

The skipper had already spoken to a few marine electricians, who suspected a neutral issue but declined to get involved. That’s understandable. Neutral faults can be notoriously tricky to diagnose and fix. With a fault on the live, you can easily verify voltage and track the problem. On the neutral side, though, things are far less straightforward. Fault finding gets technical very quickly, and with time running short, mistakes weren’t an option.

After a detailed discussion with the skipper about how the system was originally designed, how it needed to function, and what protections were in place, we got to work. We spent time fault finding and carefully evaluating the wiring setup. Once we confirmed that all necessary protections were present, we re-wired the relevant circuits so the immersion heater could run safely from the inverter when needed.

To help protect the house battery bank, we also installed a timer module — a simple but effective safeguard to prevent the heater being accidentally left on and draining power when underway or at anchor.

We wish the skipper and his family the very best as they begin their ten-year voyage around the world aboard Shadowfax. It was a pleasure to help them get one step closer to departure.

Fair winds and following seas.
