Somebody who stays a while in the water looses water due to water pressure. That's why you have to urinate a lot when you are in the water.
So there occurs underpressure in the body when the MOB is taken aboard in a vertical position and bloodpressure drops very fast. By using a horizontal position this can be avoided.
In our RCMSAR training, a preferred method of recovery of a person from the water is by "Parbuckling". This involves rolling the person up over the tubes of the RIB, but could be easily adapted to getting the person up onto the swim grid.
Not necessary if the person can climb a ladder.
