I happen do do some offshore races on other boats, so I've adapted a few of the rules governing those boats.
Plastic covered lifelines are NOT allowed, as it makes it impossible to inspect.
On each lifeline I made it about 4 inches shorter than required, and I use light line, wrapped many times, to bridge the gap. This allows you to cut the line in an emergency, lowering the lifelines to the deck, making it easier to get somebody back on board your boat.
It seems to make sense.
