Another item of safety gear that is commonly found on other boats is the "throwable". On beach cats, a throwable is on the required equipment list for some distance races. What is most commonly carried? And, how is it carried to facilitate quick deployment? (Or, is it simply a device that is aboard to meet the requirement?)

I bring it up because I started wondering if any elements of the Lifesling method for recovering an MOB could apply to catamaran distance racers/cruisers.
