How do you separate surfing vs. plaining? Over here the ocean swell runs at approximately ~ 14 knots. In blue water you hear that number often. To me, if your boat speed/swell speed is similar, you are "surfing". When you start launching into the backs of waves in front of you, you are "getting on the step". My Moore definitely lights it up downwind, to the speed of the swell, even under reduced plain sail, but in flat water bursts up to wind speed are great and fun, but short lived... Where do you guys make the distinction??
