At Makai Yachts, we believe that a true cruising catamaran should offer more than just exceptional performance—it should also deliver unmatched comfort, efficiency, and independence. That’s why we developed our advanced Hotel Mode electrical system, designed specifically for life at sea, without the noise and hassle of a generator.
Engineered with the modern off grid catamaran lifestyle in mind, this system ensures quiet, reliable, and self-sufficient onboard power. Whether you’re anchoring in a remote bay or enjoying a marina-free weekend, Hotel Mode enables full luxury living without compromise.
The Heart of Hotel Mode: Lithium-Powered Freedom
At the core of Makai’s Hotel Mode system is Makai’s Mastervolt MLI Ultra 12/6000 lithium-ion battery option. This high-capacity, fast-charging battery pack provides all the energy storage needed to run every onboard system—including air conditioning, lighting, refrigeration, and entertainment—completely silently and without relying on shore power or a generator.
Charging is handled by two powerful Mastervolt Alpha 130A alternators, installed on each of the twin Yanmar diesel engines. Together, these alternators provide an impressive 260 amps of charging power while motoring. As your power catamaran cruises between destinations, it’s efficiently generating and storing energy for later use.
This system supports all onboard systems, even optional features like our Velair reverse-cycle air conditioning, which offers both cooling and heating with remarkable energy efficiency.
A Fully Integrated Off Grid Solution
For modern off grid catamaran owners, control and awareness are key. That’s why the entire Hotel Mode system is fully integrated with the CZone digital switching platform—a central hub that lets you monitor and manage your yacht’s electrical systems with ease.
From the intuitive CZone touchscreen display, owners can view real-time battery levels, power consumption, charging status, and switch onboard systems with a tap. The system is powered by the following advanced components:
- Mastervolt MLI Ultra 12/6000 Li-ion Battery
- Ultra Connection Kit 12V for safe, efficient connections
- Dual Alpha 130A Alternators (260A total)
- Mac Plus 12/12-50 CZone DC-DC Charger
- CZone-Mastervolt Bridge Interface for seamless integration
- CZone Digital Switching and Display Units
These components work in harmony to deliver a reliable, silent, and future-proof solution tailored for long-range cruising and off-grid catamaran adventures.
Comfort Without Compromise
Hotel Mode redefines what’s possible in a cruising catamaran. Owners can now enjoy all the comforts of home—from air conditioning and chilled beverages to ambient lighting and fully charged electronics—without running a generator.
The Velair reverse-cycle air conditioning system, designed for ultra-low energy consumption, is a perfect match for this setup. It allows for climate control even at anchor, without the hum and fumes of traditional power generation. When combined with Makai’s efficient hull design and lithium-powered electrical system, you get a power catamaran capable of truly self-sufficient operation.
Built for Exploration, Engineered for Efficiency
The Hotel Mode system is more than a convenience—it’s a cornerstone of Makai’s commitment to sustainable, intelligent yacht design. By removing the need for a diesel generator, reducing emissions, and leveraging engine-generated charging, we deliver an onboard experience that is:
- Quieter
- Greener
- Simpler to maintain
- More enjoyable for long-term cruising
Whether you’re exploring far-off islands or simply enjoying a quiet anchorage, this is the power solution that lets your cruising catamaran go farther, stay longer, and live better.
