Better systems.
More time on the water.

“Colin is a real professional: knowledgeable and attuned to how I use my boat when he offered options for a replacement lithium battery powering the Oceanvolt electric motor in my Alerion Express 28. The battery installation and sea trial were thorough and thoughtful.

When I had a question (on a Friday evening) about recharging a few months after installation, he responded overnight.  In my opinion this is great ‘service after the sale.’ “

“They were punctual, easy to reach, and did a great job of configuring a somewhat different system. No complaints, I would certainly recommend them.”

“Excellent work by first class, knowledgeable individuals.”

“The guys over at Crescent Yacht are extremely knowledgeable. They were an integral part in the restoration of my beloved fishing vessel. They did a full rewire of my boat and all three systems and even went as far as making plans for the future to switch to lithium having everything in place already. Truly appreciate Kentry's knowledge and guidance through the process. Would definitely recommend to anyone in the market looking for a marine energy system specialist.”

“I’ve got 99 problems but my Victron ain’t one!

I recently had the electrical system on my 1975 Dufour 31 sailboat completely overhauled by Crescent Yacht Systems and I genuinely can’t recommend them enough.

Working with Colin and Kentry was an absolute pleasure. They were highly communicative throughout the entire process, keeping me informed every step of the way. What really stood out was their honesty and expertise—they actually saved me money by helping me understand what I actually needed versus what I thought I needed once the schematics were finalized.

As for the installation… I’ve never seen anything this clean or efficient. Fitting a full Victron Energy setup into a 31-foot sailboat with 500amp hours of Lithium Ion batteries is no small feat, but they approached it methodically. After spending time onboard planning layout and walking me through options, we landed on a solution that maximized space without sacrificing performance.

The install itself took about two days—day one was dedicated to carefully removing and labeling existing components, and day two was a flawless install of the new system. Since then, I’ve had zero issues. The Victron system is incredible—I can monitor everything remotely, receive SMS and email alerts, and have complete confidence in my boat’s power system from anywhere in the world.

If you’re considering upgrading to a modern, self-sufficient electrical system for your boat or yacht, I can’t recommend Crescent Yacht Systems enough. Top-tier work, great people, and a result that exceeded expectations.”

“Colin and team are world class engineers and craftsmen who care about the details and how systems work for users. I’m psyched about the quality of the work, the design, and the responsiveness of the team before, during and after the install of my RV AC and wiring upgrade.”

“These guys did a host of projects on my boat over the past year. It involved a lithium conversion, dc-to-dc charger, solar troubleshooting, and more. As with anything technical, there were a few hiccups, but they were on top of every bump and always very responsive. Spend your money with these guys. You’ll be glad you did.”

“I was introduced to Crescent Yacht Systems the day I purchased my Airstream Basecamp. At the time, I was simply looking to add a single battery to complement the factory solar panels. Two years and several projects later, they have transformed it into a fully capable off grid machine that can operate independently for extended periods. Along the way, they recommended solutions I did not even know were possible and engineered them seamlessly into the build.

The technology now resembles what I can only imagine belongs in a spacecraft. Touch screen controls, real time system data through phone apps, always on Starlink internet, and fully integrated power management have turned this RV into something far beyond its original design.

Their installation work is impeccable and the engineering diagrams they provide are on another level entirely. What has stood out most, however, is the after install support. No matter the hour or where I am on the road, they have consistently responded with clear troubleshooting guidance and practical repair instructions. That level of ongoing support is rare and has been invaluable.

After tens of thousands of miles in the RV lifestyle, I can say that finding a company like CYS is so rare it feels like discovering something you almost want to keep to yourself.”
