The waves are significant in that handling the rougher stuff is definitely a
different skill than racing on totally flat water.  I have been in two races
where I pulled away from competitors that I was having a hard time keeping
up with in flat water and when we hit the open, choppy water.

I have seemed to settle in on a depth of 3' - 4' to not feel the drag of the
reflective
wake off the bottom.  What are other opinions on what is a depth at which one
is not affected by one's own reflective wake?
