Steamer or Steamship

Steamer is an early term for any vessel power by a steam engine rather than sails.

Early steamers were propelled by large paddlewheels. "Side-wheelers", with the paddlewheels on each side, were more seaworthy, and therefore more common in ocean waters, while "stern-wheelers", with a single large paddlewheel at the back, were more common as riverboats. Later, these were replaced by more efficient screw (or propeller) vessels.

This sketch of the Delaware shows the remains that you can expect to find of such a vessel.

Of note is the universal pattern of:

< bow - boilers - engine - drive shaft - propeller - rudder/stern )

and the fact that the boilers are always in front of the engine. Identify any one of these features on the wreck, and you can orient yourself in even the murkiest conditions.

Here is an assortment of large sharks that can be found in New Jersey waters, by no means all of them. These are more likely to be found offshore in oceanic waters. Sharks are seldom a danger to divers, they seem to be put off by the noise and bubbles. Nonetheless, all should be treated with caution.

Realistically, sharks in our waters are not a great concern. In over 350 northeast ocean dives, I have seen sharks on only several occasions ( not counting harmless little Dogfishes ) and only once while in the water. That one was in the Mud Hole, on the Arundo, to be precise. It was a Blue, or possibly a Mako, and wanted nothing to do with me, which was a relief since I had half an hour of deco left to do at the time! That would have left me very bent otherwise.

If you think about it, humans must taste terrible to sharks, and scuba divers especially - with rubber suits and big metal tanks. Many shark attacks occur in murky water where the shark is not sure what it is attacking. Some attacks have been the result of the shark being stepped on in shallow water. Most shark attacks on humans are abortive, the shark taking only one exploratory bite, then realizing its mistake and breaking off the attack. Unfortunately, with a large shark, one bite and you're dead. Many predators, from bears to tigers, will prey on humans when sickness, injury, or old age make them unable to catch their normal prey. Sharks are probably no different.
