Beam of the hull seams to play a big role how boats manage the chop. Even though a SR 5.4 is not the softest ride(guess most of the bigger ribs beats it easily) have noted many bigger(and wider beam)hard boats are much worse. One of my favorite islands is located approx 35 nm east of where i live. Predominant wind direction is SW. In the morning when going there we have close to following seas, typically moderate swell and small chop. The wind often increases during the day and the trip back can be rather rough with mixture of old swell, cross waves and heading seas chop. The SR manages it pretty ok, active throtle handling, zic zac routing avoiding the worst waves. Sometimes increasing speed does the trick. Hardly ever any other motor boats around in those conditions or if any, they are mostly doing very slow progress, displacement speeds.
That's the great thing with good Ribs, even though its not always soft or easy, you can still do the trip and come safely home when other boats of similar size might better stay at the marina.
fun on a boat is inversely proportional to size...sort of anyway
