I am sorry to hear that, we had the opportunity to meet Wayne Hasson several years ago at the Our World Underwater Show in Chicago years ago and he was very personable and friendly.
Every year the Scuba Hall of Fame on Grand Cayman honor locals that have promoted diving in Cayman as well as inducting International Hall of Fame winners. In 2018 Wayne Hasson was named a local Honoree and they published this bio about his life and work:

Wayne Hasson
Wayne Hasson has been leading divers to the sea for most of his life and has probably spent more time underwater than above. Along the way, he has had a significant impact on how we see and explore our world. An avid diver since 1967, Mr. Hasson began his love affair with the sea during an eight-year stint in the Marines, where he certified scores of his fellow warriors and their family members. After departing the Marine Corps in 1978, he immediately began to furrow a deep trough in the dive world. Among his myriad accomplishments, Mr. Hasson founded Aggressor Fleet in 1984 and captained the first Cayman Aggressor. His approach to the luxury live-aboard concept has literally changed the way we explore the world. Today there are 12 Aggressor-franchised live-aboards.
While in the Cayman Islands, Mr. Hasson helped install the first 112 permanent moorings and took the concept and idea to Belize, Turks and Caicos, the Bay Islands, Kona and Truk. He also invented SASY (Supplied Air Snorkeling for Youth) and his award-winning photography has been featured in publications worldwide. Mr. Hasson has been a major voice and influence in the world of diving for over 40 years, accumulating more than 10,000 dives along the way, and he still spends several hundred hours a year underwater. When not diving, he’s one of the world’s greatest advocates and most vigorous promoters of scuba diving as the ultimate activity and lifestyle. Most recently, he has put together a program of marine science, diving and awareness, called Oceans for Youth, to inspire the next generation of divers.
