The aerial seen on the foremast at the start of the clip is for the new AIS system being trialled on the Pilot Star - 1994.
An early incarnation of AIS was trialled aboard the Newlyn netter, Pilot Star skippered by owner Martin Johns. At one time, Martin was invited to London to se AIS working on a huge display screen - bet he never dreamt he would be using a mobile phone to do the same a few years later - in context, 1994 was a year before Microsoft released Windows 95 and bundled Internet Explorer with it - most schools, colleges and universities only had access to the internet in specialised teaching rooms for ~IT students. A few people at home tangled with 14Kb dial-up internet access - if they were able to configure the settings! Texting on a mobile phone was introduced in 1994.
