O, the
line runs from the end of the boom forward to the bow, through a block (mine is attached to the bow
cleat with a spectra strap) and back along the deck to the cockpit.

Yup, "attentive" is the operable word, but I agree entirely -- mechanical prevention is key. Because it doesn't take much "inattention" (maybe reaching for a cup of coffee as the boat slides off a wave) for a jibe to ruin your evening.
Preventers are a pain in the ass to
rig and operate, but I find them very useful, especially when you have new/young/inexperienced crew at the helm. Preventers let you say to your young nephew, "See, that's what I was saying about not getting the wind get too far 'by the lee'," without it costing you a couple grand.
