porthole diagram

Portholes are used to let light and air into a ship. They are usually constructed of brass for corrosion resistance, which makes them highly desirable as collector's items. The drawing at right shows all the major parts:

  • The immovable backing plate, bolted to the vessel's hull, which carries the hinges for the swing plate and deadlight
  • The glass swing plate, which is secured shut by large butterfly nuts called 'dogs'
  • The deadlight, used when it is desired to black-out the vessel, as in time of war

Deadeyes (above and right) and blocks (below) were used in the rigging of old-time sailing ships. In either case, the purpose was to gain mechanical advantage through the use of compound pulleys. This was especially necessary in the days before powered winches, when the only working force onboard was literally manpower.

Deep Sea Defectives is proud to announce the recovery of the Andrea Doria's disco ball. World-famous deep-sea scuba diver John Chatterbox found the ball after mining hidden nuggets from blueprints and records of the vessel to determine its most likely location. He then did a hazardous penetration deep into the bowels of the wreck, which is lying on its side in crazy deep lotta water.

I am confounded by the illogic of many of those who try to defend the buddy system, even the spokesperson for a training agency such as PADI - the same folks who preached the dangers of dive computers and Nitrox a few years back. Here is some of the nonsense I've heard and why it is just that:

The buddy system makes diving more fun and practical

Of course, neither has anything to do with the buddy system. Fun is touted as sharing the dive and the after-dive experience with your buddy. Practicality means helping your buddy lug around equipment, get suited up, and other niceties. These benefits can be enjoyed with any dive companion without that person being a "buddy" for whose safety you are legally responsible.
