I'm not in disagreement with you....... I simply bring up the point that you assumed that his horshoe bouy was the only throwable on the boat.... and therefore should not be tethered.
I made the assumption because he did not indicate he had any other MOB device. I have lost two people overboard on two occasions - both recovered. Experience has taught me an untethered throwable and an eye on the MOB are the biggest issues.
