We talked the other day about the differences between radar transponders and AIS transponders, because we are often asked what are they when we explain the benefits of AIS. We found today a very interesting conversation in La Taberna del Puerto, the well-known association of boaters in Spain, about an accident that took place last year close from England, particularly a collision between a 7.5m long yacht and a ferry with destination Bilbao.
There is a detailed explanation, and a report from the British Authority about the probable malfunction of the radar transponders.
There are many reasons to explain why a Class B AIS transponder is far superior to a radar transponder. It is important to understand that, nevertheless, no electronics nowadays will be able to substitute a good captain on board.
