At the time of induction into the Hall of Fame, Rognvald still held all the Orkney Open short course backstroke records at all distances (50m, 100m, 200m). All of these were set in the early 1990s so have stood for nearly 30 years. Rognvald also represented Orkney at Junior Inter-County from 1983 to 1988. During this time, he broke the JIC 50m backstroke record. He is a former North District record holder and gold medalist for 100m backstroke.
Rognvald represented Orkney at Scottish Schools, winning gold in the 100 backstroke in 1988 and silver in 1989. He was a member of the Scottish Senior Swimming squad from 1988 to 1991, and Scottish Universities backstroke champion for backstroke in 1990. He has had 2 caps for Scotland, as part of the Scottish Team who went to the annual Southampton Open Meet in 1989 and 1990 and was formerly ranked #1 in Scotland for 50m backstroke.
