Yes, cruise ship are lit up,
and so are Oil Platforms, and other working vessels, and tankers,...and so are coastlines...That is not the point...I don't care if someone wants to turn all thier lights on, even though it is not the best way to get noticed, and very poor seamanship...I've sailed myself out of all kinds a messes others have caused, and quite a few of my own design, so I'm confident I'll get by, just don't tell me the rules support it when they don't...OR that it makes good sense to have "turning all your light's on" as lighting SOP on your 40 foot sailboat...cause it doesn't.Ed, as to your question about cruise ships, vessels over 50 meters have many different rules than smaller vessels...There are other differences of rule for vessels that carry passengers for hire...many differences, but I'll just mention one rule...thier nav lights are required to be stonger -more visable at greater distances- and out shine lesser lights on board. For example, your mastheadlight,if you are required to have one, must be visible at 2 miles... a cruiseships masthead light (yes they DO TO have one)must be visible for 6 miles. Thier other nav lights are also required to be stronger & brighter... When in a closer proximity to a cruise ship,they look very bright, but when you see one from a distance and are trying to figure out if you are on a collision course, you can see thier regulated-ly brighter nav lights easily ... Also,those that are steering the ship are on a bridge that is not all lit-up,it is isolated, and kept 'red lighted', most of the time...Those steering the ship do not see all those lights and the fact that on my little sailboat I might be blinded by my own lights is just one reason the NAV Rules don't want me to turn on all my lights...I am not saying it is perfect...Just two years ago off the California Coast as I was set for Alaska, I thought an oil rig was moving! I was flipping out because we were on a collision course and he shouldn't even be moving!!! AAAAHHH!!! I turned to starboard and gave way, way away... Turned out to be a fishing vessel, with enough lights lit to be a major league ball park with a night game going on...I couldn't see his nav lights at all through the brightness of everything else he had on, and when I raised them on VHF, they hadn't seen me at all over there own lights or on thier radar...
