One guy sleeps on his bedroll or bean bag on the starboard side of the livewell (center of dance floor), one guy sleeps on the port side. Third guy sleeps in the V-berth on the cushions which is the noisiest due to water smacking the hull, and the fourth guy sleeps in a bean bag on the deck in the house next to the helm chair.
The best spot, quietest and least motion is in the bean bag aft on the dance floor.
