Nautic Check offers information, practical advice and safety recommendations about everything you need when you go sailing or in motor boats. Statistically, 60-70% of maritime emergencies occur in recreational boats. Statistics also point to human error as one of the major causes of problems, followed by mechanical failures. Ignorance, lack of adequate and mandatory material or its misuse could aggravate any risk situation.

It is not a simple and tedious checklist: In just seconds you can setup the features of your boat, the duration of the trip and the equipment on board.
