You've got your facts on the visibility issue down pat. My father, who was a sea captain imparted your formula to me based on someone on the bridge of a ship and your numbers work almost to a tee.

The other benefit to rigs 10 or 12 miles off the coast is the reef effect that results. Fishing the rigs has been nothing but spectacular off the Louisiana coast.
