The times I used them they went south out of the Hillsboro Inlet. They are quite close to the Boca Inlet, but it gets so shoaled up plus it is small. I would think a big boat like that would have a really hard time getting out of the Boca Inlet, at least as the inlet is now.
When the dive sites were south, closer to Hillsboro inlet, we would go out of Hillsboro inlet, otherwise we’d use Boca inlet. There has been times when we had gone out of Boca inlet and forced to come back through Hillsboro inlet due to rising seas, same as up in Jupiter when seas are big and we were forced to use WPB inlet, but Boca and Hillsboro inlets are much closer together than Jupiter and WP, hence why Dixie could use either inlet on the regular.
Worth noting too that the issues with the inlets (both Boca and Jupiter) are really only at play when we have big seas, I mean, it still sucks they have a shallow sandbar in front, but captains can navigate it just fine in calm seas, but when it gets big it gets gnarly real quick, remember green boat at Jupiter this winter?
The shallow spot in the Boca inlet been like that for a long time, if I’m not mistaken, Capt Tony from Diversity was the guy who put a beach chair and set on it right outside the inlet as a sort of protest to show how shallow and dangerous it was, calling attention to the issue.
I used to work for Dixie back in 2008/10, but like I said, it’s been just about that long since I last dive with them.
