On the USS Nightmare we use the floater system, with 4-6 'breakers', depending on the night. Generally, our breakers are seasoned actors who know the boat, know the scenes, and can fill nearly any spot. It's kind of an 'honor' to be used as a breaker.
We have a break deck at the back of the boat. Picnic tables for seating, snack foods, and, of course, loads of water and cough drops.
