Re: Island Greens
i dont have the exact dimensions handy. the approach is from the left of the pic. (the foot bridge is perpindicular to the fairway.) if you are at waters edge in front of the pin, its no more than 30' left-to-right you have 40-50 feet.
the back is sloped up like that for two reasons. first, it hides the basket from the road (a design requirement of the owner). second, it provides a stop for discs that come in high or hot. a flat green would result in skips into the water. the burm actually makes things easier cuz it prevents skip-aways that would cost a stroke. there is far more latitude left-right, but you really need to get the distance correct.
i think i'm going out in the next coupla weeks... i'll get specific measurements and some new pics... it is starting to look nice and green there.
