I'm going out this weekend hopefully with some more people and i will be running around 1750lbs of ballast plus passengers. This should give me much more to work with....and i will try to remember my camera this time!
Remember that weight in the back rear corner is going to form the shape and give you the height of the wave but as you move weight forward the surfable part, "sweat spot", will get longer allowing you to surf without the rope. It is a fine line because you lose the height as you displace more of the bow in the water. I am stoked to hear that you are surfing behind the 180. It is hard to displace enough of the hull on smaller boats to produce the desired surfwake without it getting too low in the water.
