The Great Isaac was a very large V4-M-A1 class tugboat, but not large enough to survive being gashed six feet deep in the engine room. The wreck now lies intact on its port side, buried to the mid-line. It is one of the premier wrecks of southern New Jersey. Both the "Offshore Tug" and the "Inshore Tug" probably derive their names from their proximity to the Great Isaac, and may not be tugboats at all.

A dive knife should also be considered standard equipment since many dive locations have hazardous monofilament in which you can become entangled. Don't skimp on your knife either - the most commonly found artifact off the New Jersey coast is the cheap dive knife that has slipped from its sheath. When looking at knives in the store, scrutinize the locking mechanism and the sheath. Is it secure and unlikely to release by itself, yet also easy to use? Will it loosen under use, or break with age? Tug at it, and try to see if you can work it loose without actually hitting the release. If you can, then don't buy it. Also, bigger is not necessarily better - many of the best knives on the market are only 10 inches long overall.

Some other features to look for in a knife are:

  • Blade shape: blunt tipped blades are safer, while pointed blades are more useful if you are into underwater hunting.
  • A good big sturdy handle: you will probably have thick gloves on.
  • Metal-butted handle: useful as a tank banger, or light duty hammer.
  • Saw edge: for heavy duty cutting.
  • Quick release depth compensating straps: much better than buckles.
