HVO aboard Whisper Yachts: freedom without compromise

5

Whisper Yachts is reinventing responsible cruising: fully electric propulsion powered by solar energy, complemented by a clean backup solution—HVO.

This new-generation biofuel, derived from recycled organic materials, maintains the slow cruising philosophy, even in difficult conditions: extending range and ensuring energy security, without resorting to fossil diesel.

HVO: the most advanced biological fuel

HVO (Hydrotreated Vegetable Oil) is now considered the best sustainable liquid alternative:

  • Up to 90% reduction in CO₂ emissions over the entire cycle
  • No fine particles, virtually zero smoke
  • Biodegradable, sulfur-free, and free of harsh odors
  • Performance equivalent to traditional fuel

It allows Whisper Yacht owners to sail far and wide, while aligning their environmental footprint with their values.

Smart integration on board

The main propulsion remains 100% electric, with solar energy continuously recharging a battery bank sized for long-distance cruising.
HVO is only used when necessary, in order to:

  • Ensure longer ocean transits
  • Supplement solar energy during periods of low sunlight
  • Maintain quiet navigation in all situations

We don't sail "on fuel": HVO protects electric navigation when nature demands it.

Silence, nature and autonomy

Whisper Yachts offers two complementary experiences:

 

Mode of use

Energy consumed

Sound

Footprint

Solar & electric navigation

Sun + Batteries

Totally silent

Zero direct emissions

HVO top-up refill

HVO biofuel

Very discreet

Very reduced carbon

 

This model makes possible:

  • extended nights at anchor
  • exploration of protected areas
  • almost total absence of disturbance to wildlife

HVO: a pillar of sustainable yachting

Why Whisper chose it:

  • Solution now available in more and more marinas
  • Compatible with existing nautical infrastructure
  • Supported by the global energy transition
  • Contributes to an immediate shift towards an oil-free future

It's not the final destination, but a smart step towards absolute zero emissions.
