It could be the boat. I’ve been on the Sundiver Express many times and don’t have any problems with them. In fact, they are one of the few boats you can count on to go out every weekend, even if the forecast isn’t ideal. The only reason people may be hesitant to use that boat these days is that they recently lost a diver. Well, they left the dive site without the diver, realized she was missing, and came back right away to look for her. The body was never recovered. My take is that the diver had an accident underwater and drowned, so it wouldn’t have mattered if the boat was there to look immediately or not. The dive site covers an immense area and depths are well below any normal limits for a search. Since she didn’t wash up on shore somewhere it’s safe to assume she sank. Its sad but I wouldn’t fault the boat for the accident.
As for me diving that day it’s highly likely I can go on a boat trip that day. It’s much more likely I can do a local shore dive. So if you end up scaling back your plans for any reason to 1 or 2 dives let me know. I can’t promise but better chance.
