Fleet visibility
Your guests remember smooth journeys.
Weather is one of the most common sources of charter disruption. With MWI Yachts, it becomes one of your greatest competitive advantages. Consistent ETAs, proactive communication, and journeys planned around comfort: the details that drive 5-star reviews and repeat bookings.
Proactive communication
Your guests are informed before they need to ask. Weather decisions are explained, not just made.
We know what's at stake
Weather is the most common source of disruption in yachting.
And the least controlled. Here's why that matters for every passage and every programme.
02 Planning
Unpredictable ETAs break the charter programme
Port reservations, provisioning, guest schedules, everything depends on a reliable ETA. When weather forces a deviation, without expert support, captains navigate alone under pressure.
03 Charter experience
Weather disruptions cost 5-star reviews and repeat bookings
Your guests remember rough journeys. Charter companies with the best weather intelligence convert first-time clients into repeat bookings, and bad weather into a competitive advantage.
04 Cost & efficiency
Suboptimal routes inflate fuel bills by 20–30%
Fuel is one of the largest variable costs in yachting. Weather-optimised routing doesn't just protect safety, it directly reduces consumption without compromising comfort or schedule.
Ocean racing expertise
The same expertise that wins ocean races: at your captain's fingertips.

Testimonials
What captains say.
Several times during our family trip around the world, we requested Christian's advice. Global weather systems are changing, and even in good seasons we sometimes faced tricky forecasts. Christian's knowledge and analysis gave us the confidence we needed to set sail. He then maintained a constant watch, which allowed us to enjoy the highest level of serenity at sea. Thank you so much, Christian, and thank you Marine Weather Intelligence! Christian's knowledge and analysis gave us the confidence we needed to set sail.

As our Nordic tour comes to an end, I would like to extend my sincere thanks to the MWI team for the quality and reliability of your routing and advice. Covering more than 7,500 nautical miles through unfamiliar and challenging regions, the successful completion of the final leg from Brittany to LGM, without incident and within a very short timeframe, would not have been possible without your highly effective support.
