1) Sailors know that there are cables...and there are cables: Neither show particularly well that they have been dangerously compromised. Stressed cables (or sailboat shrouds/halyards) can unravel or reveal "fishhooks", indicating a severe weakness.

Like knots in rope, cable ends are especially important: Swaged cable ends are far superior to clamps, but neither connector can be counted on when the cable has any plastic coating, such as found on self-coiling cable.

A chain that has been compromised will stretch, but only an expert's eye (or measure) can determine if the chain is still safe. Tow truck operators will give away stressed chain (if you're using it for securing a canoe to a tree, say).

2) I discovered first hand why trailer chains should be crossed: If they are not crossed, and the towing vehicle's hitch requires a longer length of chain than provided by the trailer, the entire "safety-chain rig" can be compromised in a sharp turn. (You can straighten the hook, skew the eye, or even bend the trailer neck).

Crossed chains self-cancel the effect of a sharp turn. The "cradle-effect" is a bonus.
