Canal Tenders are miniature tugboats, built for tight spaces and shallow drafts - exactly what you would need for canal service. These boats and their sisters operated on the New York canal system for many decades, doing whatever needed doing.

A lot of people were up in arms over the reefing of these and other canal vessels. But what do you want - the whole world filled with worn-out tugboats? Reefing is better than scrapping - these boats will go on to a long productive life of a new sort. The alternative is melting them down into license plates and razor blades.

Tender 7 gets some air while a big green claw tosses junk on the reef.
Tender 8 is behind on the barge.
Tender 7 is lowered onto the Smithtown Artificial Reef.
Then it is Tender 8's turn.
The claw seems to have run out of stuff.
You can see all the holes that were cut in the hull. No waiting 8 hours for this one to sink!

These two should be called Theodore and Hank:

Scuba Cylinder Specifications

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
