Err no irony intended, just fact! Starovich said that "12 miles or 24 miles makes no difference to RIB users, you can only see for 3-4 anyway"
Which would be about right if the light was at sea level. However, most lighthouses I've ever seen tend to be on clifftops which puts them above the horizon of a viewer in a RIB. Ergo, the light would be visible to a person in a RIB from much further away than 3-4 miles. In fact about 12 in my guesstimation.
