We made the passage 2 weeks ago. Recommend leaving Cape May at the beginning of flood tide, and you can ride favorable currents all the way up the bay and thru the C&D canal. We do not attempt the passage with a north wind that exceeds 10 knots, southerlies and easterlies are fine. Stay out of the ship channel to avoid confrontations, just to the east over the flats is fine, but look out for oyster stakes, crab points and the occasional pound net. An alternative to Chesapeake City is the small city marina at Delaware City. The basin at Chesapeake City has soupy bottom, and this time of year you cannot count on the free dock as it is filled with cruisies. Have a good trip.
