Both RADAR and AIS instruments are precious aids in preventing the risk of collisions at sea. The way they work is based on totally different technologies. A RADAR transmits radio signals, receives their echo through a rotating antenna processed, and shows them on the instrument display. An AIS transmits and receives a vessel's navigation information on dedicated VHF channels and calculates the potential collision risk.

RADAR first and AIS more recently have spread fast in the leisure maritime world. The two instruments complement each other one is not a substitute for the other, and each has its pros and cons. Find out more in this detailed course aimed at captains and crews of small vessels.

Global Solo Challenge

The Global Solo Challenge is an around the world, single-handed, non-stop sailing event by the three great capes for yachts from 32 to 55ft. Its unique format makes it budget friendly and environmentally conscious. It starts in A Coruña in September 2023. Marco Nannini, the founder of the Global Solo Challenge, has won his class in the 2009 Single-Handed Transatlantic Race (OSTAR), was second overall in the 2010 Round Britain & Ireland Race, has competed in the solo transatlantic Route du Rhum 2010 and came second overall in the RTW Global Solo Challenge 2011-2012 on his Class40 Akilaria RC1 designed by Marc Lombard. He was nominated Sailor of the Year in his native Italy in 2012 and was awarded a medal of merit by the Presidency of the Italian Senate for his circumnavigation. Marco Nannini worked as a banker in the City of London before quitting his job at the age of 32 to sail around the world work within the short-handed offshore sailing scene.
