Who we are
Precise weather forecasts and personal consultation for safe decisions at sea and ashore.
Built on 27 years of experience.
Standard forecasts rarely go far enough.
General forecasts provide a useful overview but are often too broad for decisions on board. When leaving harbour, sailing to the next port or planning a longer voyage, you need information suited to your sailing area, boat and schedule. That is why we combine SEAMAN, the right GRIB data and direct support from our meteorologists.
Three ways to the weather support you need.
Plan independently with software and GRIB data, or bring our meteorologists directly into your decision-making.
01
Software, app & data
SEAMAN PRO for advanced passage and route planning on a computer, SEAMAN for a quick briefing in the web app. Plus compact GRIB data for cruising and racing.
02
Direct meteorologist support
Passage consultations, Atlantic planning, departure-window monitoring, or forecasts by SMS and email. You work directly with our team.
03
Build your knowledge
Recorded marine-weather seminars and specialist books help you make better decisions on board.
