If you guys are afraid to be tethered to the boat, why are you NOT afraid to trapeze? That trapeze wire is certainly a type of tether.

Rick almost drowned one time because he was on the trapeze and got knocked off the back of the boat. He was being dragged upside down and could not get himself upright. At least he had the presence of mind to grab the rudder and turn the boat into the wind and stop it, so he could right himself and get a breath of air.
