Sunil and Eddie...
In my case, I nixed the peninsula idea right away because it would take too much water square footage in return for access square footage. My proposed pond shape will not work well with a man-made peninsula. The dock will be installed directly next to a small boat launch. I anticipate the launch to be poured concrete, about 12' wide. The dock will work very nicely and efficiently with it. A covered patio at the end will be a super bonus.
