I took my '87 C34 from the Barnegat to Worton Creek on the Chessy via the C&D canal several years ago. Pretty much any NJ inlet South of Ocean City & North of Cape May should be approached with utmost caution, especially near low tide without local knowledge. Same thing goes for Delaware City Marina. Especially if you draw more than 4 foot. For DE City, Marina they're happy to give detailed directions over VHF. My low tide approach in to DE City Marina 4 years ago from the South was to keep #1 buoy in to the Delaware City Branch Channel, within a boat length to port then follow a direct path to the docks on the Northern side of the channel. I think once in the channel slightly favor the Southern side but that detail is a little fuzzy.
Enjoy the trip!
