01 Safety
Extreme weather endangers crew, guests, and vessel
Convective zones, fronts, large swells and gusts don't announce themselves with enough warning for a captain relying on generic apps. At sea, or at anchor, the margin for error is zero.

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 passages. 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.
The Platform
Built the way captains actually work.
Not a generic weather app. A dedicated routing intelligence layer, human experts backed by AI, accessible at any hour from anywhere.
Each route is built around the yacht's specific characteristics and technical constraints.
Optimised consumption without compromising comfort or safety, reducing costs by up to 25%.
Supporting guest experience, port coordination, and fleet planning with precision timing.
Routings are continuously refined by weather experts and optimised to reflect the yacht's real behaviour at sea.
Direct access to a dedicated routing expert, ensuring continuity and accountability at any hour, in any region.

Know before the weather becomes a problem.

Testimonials
What captains say.
Grâce à MWI Yachts, nous avons pu anticiper une dépression en Méditerranée avec plus de 36 heures d'avance. L'équipe a ajusté notre routage en temps réel et nous avons évité des conditions vraiment dangereuses.
What sets Marine Weather Intelligence apart is the human expertise behind the platform. Our routing expert is reachable at any hour, that level of service is unmatched in yachting.
We reduced fuel consumption by over 18% on our Atlantic crossing last season. The platform paid for itself within two passages.
