When I had my 18' Southwind, if I were to put my diverter all the way up, I felt the boat lift when in it all the way. When i put the roost down a bit, there was a point where I felt the boat go faster. The "sweet spot". The sweet spot was when the roost was about 5 foot tall.
I have been having issues with my diverter on my deck. Earlier this season I noticed that I am only getting 1/2 way up. (insert joke here)
When full up my roost is big. I was playing with it (insert another joke) a few trips ago and noticed how free the boat rides. I made a GPS pass yesterday with my diverter full up. (its stuck in manual adjust in a fixed position mode) It was real hard to get on plane, but once it was, she was feelin loose.
With my full up, I have made the best GPS pass to date. 82.3 mph. I was shocked. I am use to full up roost being slower, not faster. Anyone wanna chime in on why?
I have a droop, and a one deg up wedge. I am thinking of more up.
