The Dubliner, who was just 22 years of age, competed on the PWA World Windsurfing Tour and had just returned to the world windsurfing stage in 2012 after being sidelined for most of 2011 by a serious ankle injury.
According to website Surfdock, Clancy was nominated by Outsider Magazine for their People of the Year Awards recognising his strong comeback, including a year-best 13th place at the Cold Hawaii Classic in Denmark last October - and this 25-foot monster wave he ripped off the Donegal coast last March.
As recently as a week ago the young windsurfing talent shared his thoughts with windsurfing website Continent Seven on the year past and his hopes for 2013 on the waves.

Mikey Clancy's family has since passed along details of his funeral this week for the Irish windsurfing community.
