I have dove the st shore dives when blown out, 4 years consecutively for a week each and on the boat 3x. Viz is normally brail diving and a few planks and maybe if your lucky a boiler. The boat dives when they do go out are worth it, the u85 and the Jackson are huge dives with lots of history, the Jackson especially... The advanced is a great dive as well but when I dove it the viz was less then 8’...
