Green Ruby is built around verifiable sustainability rather than slogans: solar power, a seawater cooling system designed to cut energy use significantly, advanced wastewater treatment, and plastic-free operations - combined with quieter, lower-impact routes through Lan Ha Bay.

We have begun the path toward Green Globe certification - the independently audited, GSTC-accredited, EU-recognized standard. The on-site audit takes place once the vessel is operational, and we'll share our certification status transparently as it progresses.

A rooftop solar array supplies an estimated ~25% of onboard power during daylight hours, working alongside our generators to reduce fuel use, while a seawater cooling system is designed to lower cooling energy. We'll publish verified figures once the vessel is in service.

All onboard wastewater passes through advanced biological treatment before discharge. We're also eliminating single-use plastics across the vessel - refillable glass bottles, bulk amenities, and plastic-free supplier packaging - so nothing from your stay ends up in the bay.

Green Ruby is committed to sustainable tourism and environmental protection. Conservation and community engagement activities may be offered periodically as part of our sustainability initiatives.

Our AI concierge - currently in development - is designed to help guests with requests, recommendations, and information in their own language, before and during the cruise. We'll share its full capabilities as the service launches with the fleet.

We're building multilingual support focused on English, Chinese, Korean, Japanese, French, and Vietnamese, so international guests feel at home throughout their journey.

Connectivity in the bay is traditionally weak, so we're equipping our vessels with Starlink satellite internet to provide reliable WiFi where most boats can't - though we also encourage guests to unplug and enjoy the bay.

Mobile coverage can be patchy among the karst islands. Our onboard WiFi is designed to keep you connected when you need it.
