Hank,

Coming from a non-DIR point of view makes your admitted laziness an 
acceptable reason IMO. Not that I've ever heard it mentioned anywhere, but 
I am guessing that laziness is not considered DIR. <g>

Indeed there is a difference between a runaway horse and a boat. A boat is 
a lot stronger than a horse and you can't calm the sea down with a carrot 
and a pat on the neck.

Regardless of how long your Jon line is, if you are holding on to (or 
attached to) one end, and it is totally taut between you and the line, if 
the boat goes up (or down), you get yanked along with the anchor line. Just 
less so than if you are holding on to the anchor line itself. At least this 
has been my experience. If it is really rough, I may hold on to the middle 
of my jon line AND the loop at the end and just let go of the middle part 
if the anchor line is pulled suddenly, thus creating slack so that I am not 
suddenly yanked up as the boat moves. Otherwise, if I am holding on to the 
end and my elbow is bent, my arm can take a lot of the shock without 
jerking the rest of my body around too much. I am so used to doing it this 
way that I do not find it to be a chore at all. As a matter of fact, when I 
first started diving in the NE, I used a jon line that was attached to the 
waist strap of my harness, but found myself being jerked all over the 
place, and ended up holding on to the middle of the line anyway to prevent it.

The easy escape is definitely a plus regardless of whether or not you're 
attached to the other end. I've left more than one jon line on the Wahoo's 
moorings and anchor lines because it was just too rough to hold on to the 
anchor line while slipping the rest of it through the loop at the anchor 
line end. This was before I was a crew member, I hope it didn't cause any 
hassles. ;)P
