After talking to Peter I learned that you can get a Skater in whatever deck height you want because they are all custom built. The Skater in the picture appears to have a very low deck Height which makes it appear to be a smaller boat.
Scott Conrad has two 40's at his shop, one with a very low deck and the other looks like a fairly standard height. The one with a cut down deck looks like a smaller boat parked side by side but the running surface is the same.
Since the Nortechs have cabins i would assume that their deck height is fairly tall?
