RE: [PSUBS-MAILIST] limits

David,

The most dangerous limit is the envelope for a jammed-planes emergency that is quickly driving you deep. Of course in the worse case instance, your main motor sticks at full throttle. While you might snicker at this scenario, it has happened a number of times. This is one you don’t want to figure out experimentally. J

The obstacle course is a very good idea. When learning to dock a large vessel, a good way to practice is to set down the outline of the docking space with anchored floats. Then when practicing docking, the only thing damaged if you flub it is your ego.

    Although overboard in "what ifs", the last thread was quite entertaining. I have decided that once in the water, I will construct a small obstacle course of obstuctions such as water filled balls or other safe to hit items. I will then use this determine the limits of my sub at differing speeds by simply placing it thru its courses.

    I will develope a "safe operating envelope" specific to my boat. In operating it outside of this test area, I will then attempt to remain within this area of safety. Prevention is the best way to avoid accidents in the first place.
