I've never gone in or out that inlet. I have only gone past it on the inside while traversing the NJICW or well outside. The NJICW is what is marked as far as I know. I think there is nothing marked going out the inlet. I've also heard that you have to be sure to follow that dogleg that you can see on the chart. There is shoaling right out in front. I think it is unmarked because the shoaling is ever changing. Google Maps gives a pretty good impression where the shoaling and the deep water is.
I'd guess that with good visibility, it could be safe to follow larger boats in and out of there. There certainly are a lot of boats going in and out from Beach Haven. This seems to be the very definition of a place where local knowledge is critical, and I don't have it. But I've also heard that depth is not an issue as long as you follow the right course (the ICW was at least 30' deep just inside the inlet IIRC). On a relatively calm and clear day, I'd suppose that the breaking waves will give you pretty good visible information. I saw "The Escape Artists" on YouTube go out through that inlet on a rough day without anybody having local knowledge. A few days later, they ran aground outside Cape May in the dark and had to be rescued by TowBoatUS and towed into the anchorage with a damaged rudder. That was an interesting episode!
In Episode 13, they started out from an anchorage right in front of our marina and travelled the ICW to Little Egg Inlet ... I think they may have avoided Barnegat Inlet by reputation only to choose the inlet that is even trickier ... but, that may be up for debate! ...
