This is the case even with standard chest type harnesses according to information I received in the mid 80's. Anything connected to the body where the pull is around the sternum area will likely pull one under the water at speed. The issue isn't the crotch straps it is being attached to the yacht at speed when in the water. This has been or is being recognised in the racing side of sailing where wearing harnesses on high speed yachts is now being questioned. Better to be in the water and a yacht coming back, than being pulled along with all the risks of drowning.
