Roll Over and MOB.........the recovery!

[MidLandOne]

Tie a light line to the EPIRB and throw that - I reckon I could throw an EPIRB 50 foot no problem.

At last, sensible use for the EPIRB in the Challenge.

I may have missed it, but throwing the MOB pole would be my first step. Assuming there is a way to manuever the boat, after the MOB pole was deployed, I would get the boat close enough to effect a rescue. I would never get in the water until it was a last resort, and I knew I was within range of a rescue.
First and most important, you must provide a method to locate the MOB, as when you get in the water, you will not be able to see him/her.
Second, staying ON the boat should be a priority, as your ability to rescue the MOB will be hampered by cold water, and physical excertion.
Third, you must consider the condition of the boat. Will the mast pose additional dangers while attempting a rescue? Is the boat holed? Your MOB can not be rescued if there is no place to rescue him or her to.
