: But I promise that I wasn't on drugs last night when I came up with the idea

: always know if its deployed and how much. It doesn't require a hole

: of a hard anti-skeg for simplicity and reliability.

Although this concept may be a bit different, there is something inherently sensible about using an "air skeg" to control the way the wind affects a kayak. This keeps wind related handling characteristics and water related handling characteristics separate, whereas the drop skeg mixes them in a way that can be problematic. There have been many times when the wind and waves were at odds that a drop skeg was either useless or created unpredictable behavior. However, I think a better approach is to design the boat to be neutral in the wind, leaving the paddler free to deal with water related handling.
