The only Tyronsea I ever sailed was the 330 which my late father purchased from Court Yachts, WA in around 1987 or so and was the board he learnt to windsurf on and which he enjoyed sailing. I think they were a good brand but obviously did not make the transition out of the 80s.
The Tyronsea mast base and universal was pretty much a good wave sailors choice in 1986-87 as a mast base system at least for me and I think others. They must have sold a lot of those for many years after.
The Stinger was designed by Scotty O'Connor but must not have lasted in the range according to the above catalogue which does not mention it. Never sailed that one.
Peter Dans was sponsored by Santosha (Greg Laurenson) and Neil Pryde and was windsurfing in the speed trials at Woodman Point - summer 86/87. He must also have been sponsored by Tyronsea as shown in the sail he is using there which does not appear in the catalogue above presumably being a special speed sail.
