Designed to be the greenest cruise vessels ever built—sustainability engineered into the platform.

Engineered. sustainability, not marketing

 

BTY’s
sustainability is built around sail-first propulsion, regenerative power generation, hybrid-electric systems, and battery operation in sensitive areas—supporting both guest perception and long-term regulatory resilience.

 

Sail-first propulsion

Wind is the primary driver
whenever conditions allow, delivering quiet operation and authentic sailing.

Regenerative energy

Power
generation via rotating propellers while under sail, stored in onboard battery
systems.

Hybrid-electric system

Methanol/diesel hybrid-electric
propulsion designed for best efficiency across load profiles.

Battery “whisper mode”

Low-speed
operation (3–4 knots) without generators—ideal for night and sensitive areas.

Future-ready architecture

Prepared for fuel cells and evolving
green fuels as the ecosystem matures.

Responsible materials & waste

Certified wood, eco-friendly
coatings, and advanced waste/grey/black water treatment under strict
regulations.
