New Jersey Scuba Diving

DPC-19 "JJ"

Well, it's that time of year again, time to renew the web hosting. And for those of you that don't know, that has become a lot more expensive than it used to be. Fifty dollars a year is now several hundred. Not to mention the price of domain names has gone up ten-fold.

And I just found out that the nice folks at PayPal disabled all my Support buttons, and I never got a notice (although that may be my fault.) In any case, it is all working again now, so if you would like to make a small donation to help defray these costs, it would be greatly appreciated.

DPC-19

Built in 1943, by George Lawley and Son of Neponset, Massachusetts (hull #1307) as the DPC-19 for the United States Defense Plant Corporation. The tug was transferred to the United States War Shipping Administration, where the tug was re-designated as the WSA-2.

In 1949, the tug was acquired by the Kehoe Transportation Company of New York, New York, where she was renamed as the Clayton P. Kehoe. In 1949, the tug was acquired by the Lakes Tankers Corporation of New York, New York. A division of the National Marine Service of St. Louis, Missouri, where she was renamed the Canal Cities.

In 1972, she was acquired by the Reinauer Transportation Company of Staten Island, New York, where she was renamed the Curtis Reinauer. In 1988, the tug was acquired by J.K. Marine Incorporated of New York, New York, where she was renamed as the K-2.

In 1999, the tug was sold, and reefed under the name "JJ".

DPC-19 had her profile altered at some point, DPC boats did not have moveable pilot houses. The modification was done for operation on canals and inland waterways.

Exposure Suits - Drysuits

drysuit

Serious New Jersey divers wear drysuits. A drysuit is a waterproof suit with built-in feet that seals around your neck and wrists ( some have built-in water-tight gloves and/or hoods as well, ) and a waterproof zipper to close it up. The idea is that although you are underwater, you don't get wet, but this is not entirely true. No seal is perfect, and certain actions will let small amounts of water leak in past the seals. However, most of the moisture that accumulates in a drysuit comes from its occupant, in the form of perspiration. If water can't get in, then it can't get out either. Perhaps these should be called dampsuits instead of drysuits.

Still, in cold water, a drysuit is much warmer than a wetsuit. This is because you maintain a constant layer of air between you and the cold, and air is an excellent insulator. While air is also the insulating factor in wetsuits, there is a difference. With either suit, the volume of air, and therefore the amount of insulation, compresses as you go deeper. With a wetsuit, there is nothing you can do about this, but with a drysuit, simply tap the inlet valve, and compressed air will flow from your tank into the suit, and puff it up again, keeping you warm. An added benefit is that by keeping the suit inflated to a constant volume, you maintain constant buoyancy, from the surface to the bottom, which can actually reduce the amount of lead you need to carry. Some divers even dispense with the BCD, considering that a drysuit can be thought of as a full-body BCD, but this is not recommended, and it is convenient to use the BCD as a quick trimming device and for surface flotation.
