I have one on my Statos 176. It's great to get out of the sun and take a break on those hot summer days. It folds down on the deck right in front of the motor and I forget it's there. Mine has a cover over it that you have to unzip to open the top. It's quick to put up and down with only two straps with snaps that need to be hook up. My fear would be that in the up position it would catch a lot of air and slow the speed of the boat. That is not the case at all, at top end I might lose a MPH or two but I never run at top speed anyway. Mine is high to where I can stand under it while on the deck. It's not much use in a downpour but is great in keeping the sun off. I hope this helps.
