We, who are familiar with the rules of the sea, know that merchant ships underway shall display (i) a white masthead light forward, (ii) a second white masthead light abaft of and higher than the forward one, except that a vessel of less than 50 metres in length shall not be obliged to exhibit such light but may do so, (iii) green/red sidelights and (iv) a white stern light.
If these rules apply to USN ships and submarines is beyond me. State ships can do what they like.
Then there is a rule for air-cushion vessels, when operating in the non-displacement mode. They shall, in addition to the lights prescribed for normal displacement ships exhibit an all round flashing yellow light.
Finally we have the Wing-In-Ground (WIG) effect vehicles. They shall, in addition to the lights prescribed for normal ships exhibit a high intensity all-round flashing red light when they fly above the seas.
I know that USN hates to tell us where it is, but why not display a high intensity all-round flashing blue light at night to show off. When the ENEMY attacks, USN can switch it off.
USN could also use pink or yellow flashing lights to inform us where it is.
Is this a joke? i don’t get it a pink flashing light would be kind of funny though. From your comments I can tell you haven’t worked around many navy vessels. Bottom line their’s an operational problem that finally might get addressed they don’t need special rules just follow the ones that are in place. We won’t even talk about good seamanship.
