Delaware Artificial Reefs

Delaware has a string of artificial reef sites in the Delaware bay, but they are of little interest to divers. Most of the sites are quite shallow and perilously close to the shipping lanes, several of them were actually reduced for this reason. The conditions in the bay are hardly good for diving. The reefs consist mostly of concrete rubble from construction in Philadelphia and other cities on the river. Also shown is New Jersey's sole artificial reef in the bay.

Here are some dimensions and specifications for scuba cylinders. This is by no means an exhaustive list. These numbers should be taken as approximate since equivalent tanks from different manufacturers will differ slightly. The two most common models - the Catalina aluminum 80 and Luxfer aluminum 80 - are highlighted, along with my favorite, the OMS LP steel 85.

  • Weight, full - this is what you will have to be able to lift, in and out of your car, around the dock, and up the boat ladder with all your other gear. Times two for doubles.
  • Weight, empty - this is pretty much irrelevant
  • Buoyancy, empty - this is what you need to weight yourself for, so that you can do a safe free stop at 20 feet at the end of your dive
  • Buoyancy, full - this is what your BC needs to be able to support when you jump in the water, otherwise you are a "dirt dart" heading straight for the bottom and disaster
