With all due respect to Alvah -- a far finer sailor than I might ever hope to
be -- he knows diddly about the physics of deceleration.
I suggest anyone installing jacklines they think they might need check on the
requirements OSHA has for fall arresting gear for industrial workers. I
understand even with that gear, people get hurt.
Remember, stretch of 3 inches has 100x less G-shock load than a stretch of
3/100ths of an inch. Remember, it's not the fall that hurts you, it's the
stopping.
