The "China Junk Wreck" by Townsend inlet rises up to 15 ft. What you can see is a couple of boilers and a debris field. To dive it you must hit the tide just right. On a good day, you can see 15-20 ft. A good tog spearfishing site.
The "China Wreck" is the partial remains of an unidentified late 19th-century wooden sailing ship, with a cargo of china plates and cups, and miscellaneous articles. This site is believed to be the wreck of the D.H. Bills, a 167'-long wooden-hulled barkentine that sank with a cargo of British-made earthenware during a storm in March 1880.
The wreck must be dived at slack tide, and even then conditions at the mouth of Delaware Bay tend to be muddy. The plates themselves date from about 1875, and are fairly ordinary and of little value except to divers who prize such artifacts; and despite years of plunder, there are still more to be found.
The Clermont was at one time the world's largest dredge. She was sunk in a storm while under tow on January 8, 1927. Today she sits upright on a sandy bottom, partially intact, rising 15' off the bottom. Some of the dredge pipes are visible in the sand off the starboard side of the wreck. Divers have recovered several interesting objects from the wreck such as deck prisms and bricks from the boiler stamped "Weideimer".
Diving in the Caribbean is wonderful. The weather and the viz are practically guaranteed, and the reefs will be right there where you left them last time. You can plan a whole vacation months in advance, safe in the assumption that it will almost certainly work out, or at least it won't be the weather that does you in.
If it were only like that here. Diving in New Jersey can be a very hit-and-miss proposition. There really is a lot of great diving here, but nothing in the North Atlantic is guaranteed. A week's worth of bad weather, or a month, or a whole summer of sunshine and glass seas, there's just no telling.
