Ok here is a slight problem with including the bow height in a scope calculation. As you let all that chain out of the bow locker, your bow rises I was always taught that heavy things should not go in the ends of airplanes or boats - so why do so many cruisers put heavy chain and anchors on the bow and a big dinghy, arches, anchors, etc. on the back of the boat?
