According to a report from the Daily Mail, 34-year skipper David Carlin found out the hard and expensive way when he accidentally crashed his boat into a ferry while trying to use an iPad to navigate the waters, resulting in his boat sinking within half an hour and also resulting in a fine worth £3,000 for breaching maritime laws.
From what we can tell from the reports, it seems that Carlin’s boat did not even come with a compass and that he was using the iPad for navigation. However it looks like Carlin did not count on the WiFi signal dropping, thus ending the navigational capabilities of the iPad, and resulting in the accident, although thankfully it does not appear that anyone was seriously hurt.
The DFDS Seaways cargo ferry that Carlin ran into had not realized that an accident have ever occurred due to its sheer size, which was estimated to be 1,400 times bigger than that of Carlin’s 50-foot Second World War boat.
