When he begins work at the NMA (below), Mr Maslin’s initial focus will be to gain a deep understanding of its work, particularly in marine conservation and its educational role.
He said: “My time at Wembley made me appreciate the responsibilities of being branded ‘national’ and the importance of a clear vision to deliver a world-class experience based around best events, facilities and service.
“Having visited the aquarium as a tourist, I know it is an informative experience provided by staff who are clearly enthusiasts.
“I’m now looking forward to seeing if we can achieve something really special by combining my experience with the passion and talent of the team at the National Marine Aquarium.
“I look forward to working with the team here to make a significant difference in the world of marine conservation, research and education.”
David Pridden, chairman of trustees of the NMA, said: “The appointment of Roger as CEO and the top-level experience he brings with him are an exciting development for the National Marine Aquarium.
“The trustees are delighted to welcome him to the charity.
“We’re proud of the reputation the aquarium has for being a popular tourist attraction and a centre for excellence in marine education, research and conservation and we look forward to supporting Roger as he leads the team to achieving our mission of driving marine conservation through engagement.”
