Thanks to their continuous monitoring, we were able to enjoy a high level of peace of mind while at sea.

We turned to MWI when we sailed the Atlantic with our family. We wanted professional advice for the key stages. The routing advice proved to be very accurate and helped us to sail serenely. They were able to adapt the routing to our boat, our experience, the family context and our quest for comfort and safety!

★★★★★ 5/5
MWI offers thorough pre-departure planning, personalised daily support, and a global analysis far more comprehensive than GRIB files alone. Thanks to this support, we improved our performance when crossing the Atlantic and reaching New Zealand in 2024, but above all, we gained peace of mind. Having a guardian angel who can anticipate weather conditions with accuracy and responsiveness is priceless for our safety.
