John, from Neath, has just started the new role working with the 83 member clubs and training centres of RYA Cymru Wales as well as club members.
The 22-year-old is part of the National Triathlon Performance Centre of Wales, hoping to qualify for the Commonwealth Games next year, as well as a sports management graduate of Cardiff Metropolitan University and a qualified pilot.
"This is a really important new role," explained RYA Cymru Wales chief executive Phil Braden. "We need to take advantage of all the new methods of communication to improve the ways we interact with our members as well as being able to reach out to a younger demographic.
"Sailing is such a great outdoor sport that people can enjoy throughout their lives, we feel we have a strong message we need to spread as widely as possible."
John competes at a domestic elite level in triathlon and has raced in several junior European Cups, but is looking forward to his new role in a very different sport.
"I hope I can bring a new level of communication to watersports in Wales," he said.
"Some see it as a very traditional sport, but it is very popular amongst young people and we need to find new ways of involving them and letting them know what is going on.
"It is a busy time, a number of Welsh athletes are trying to qualify for the Commonwealth Games team, the majority of us are based in Cardiff.
"However there are so many exciting developments all the time in the social media world and I am looking forward to being involved in bringing watersports into the mainstream in that world."
