While the Delaware Bay is a challenge, it is a challenge because it is about 30 miles from Cape May to the C&D canal, but it is doable. Unlike most portions of the ICW there really isn't a good anchorage or marina from Cape May to the Canal. There a few good places to anchor near the entrance to the canal, one behind Reedy Island and the other near the canal itself just outside the break wall on the south. Both offer reasonable protection. Ideally he'll leave the CG anchorage in Cape May an hour or so before dead low tide, motor through the CM canal and ride the tide up to the C&D canal. If he gets there in time to ride the current down the 18 miles of the canal to the Chesapeake to anchor in the Bohemia River. We did this by leaving at 0330 and were anchored in the Bohemia River by 1700 or so. That may not be reasonable in a 22 ft boat.
In terms of managing the boat and navigating, the East River in NY can be a real white knuckled ride, especially in a small boat. At ~12 miles long and with currents running up to 4+Knots riding the current is essential. Even then there will be standing waves, upwellings, and eddy lines to watch for. It is too long a distance for a small boat to sneak through on slack water.
The best source of information I found was the Eldridge Tide book. The book has maps of the currents and critical tide information, for the Cape Cod Canal, East River, and Delaware Bay. The book makes the navigator less dependent on internet access.
I would encourage your friend to use the Bob423 FB group and to have him ask his questions here.
