You are correct. RAM shapes or lights go up when you are on the flying course. They also relate to your Periods of Danger and Periods of Caution and the status of the helicopter on the deck.Things may have changed since I was in the fleet but Flag Hotel was at the dip when Flying Stations were piped and close up when you were at Flying Stations. RAM shapes/lights were not displayed until you were on the flying course and ready to recover.
Shapes/Lights hauled down/shut off once the helo recovered and the ship was free to maneouver. Flag Hotel hauled down once Flying Stations were stood down. (Flying stations are not secured until the aircraft has left the ship and flown back to base.)
I am sorry - but (MARS/NWO) pedants gonna pedant...Reduced Ability to Maneuver
Also goes up for RASs , if you have some steering issues, and probably some other scenarios that I can't immediately think of.
It is - the argument is if a designated flying course and speed is required for launch and/or recovery or if the RPAS has a large enough envelope to make it immaterial.Aircrew pedant's gonna pedant:
What's the argument? Is an RPA not an aircraft?
I was waiting for this to happenI am sorry - but (MARS/NWO) pedants gonna pedant...
It is, directly from the International Regulations for Preventing Collisions at Sea, a "vessel restricted in her ability to manoeuvre".
IAW with those same regulations those vessels that are considered RAM are:
a) a vessel engaged in laying, servicing or picking up a navigation mark, submarine cable or pipeline;
b) a vessel engaged in dredging, surveying or underwater operations;
c) a vessel engaged in replenishment or transferring persons, provisions or cargo while underway;
d) a vessel engaged in the launching or recovery of aircraft;
e) a vessel engaged in mine clearance operations; and
f) a vessel engaged in towing operations such as severely restricts the towing vessel and her tow in their ability to deviate from their course.
Thus, yes, RAS underway, recovering a helo (or drone.. interesting argument to be had there), towing, mine clearance ops, towed sonar evolutions... there are many that apply to RCN ships at sea on occasion. (That said, mine clearance doesn't use RAM shapes, but mine clearance shapes - and a ship with no steering is most certainly "Not under Command" IAW the Regs, so that would be two black balls, one over the other).
Not under Command, by the way, is the result of some "exceptional circumstance" - while RAM is the "result of the nature of her work"
Happy to obligeI was waiting for this to happen
I wasn't going to be the one to do it though because.... well it's one of the things that drives me nuts about the NWO trade but that's probably because I spent too much time in the land of crayon eating beforehand.
Thanks for the quick reply. The reason for the questions is that I dabble with marine art and was planning on a painting depicting a cyclone and one of our frigates. Just trying to get it right!
Thanks for all the help! Really appreciate it
- flag hoist - starboard or port side?
- RAM shapes - starboard or port side?
- Scenario: the frigate is on flying course; could the helicopter make a pass around the ship before coming in for landing "surveying" so to speak?
At least we haven't started reciting Cockcroft yet! Nothing like adding a bit of British Stiff Upper Lip to that Pedantry!lol, I was also waiting for that. If I had a red canoe and a green kayak, I would also put them on the 'wrong' side of a car rack(ie red on the passenger side) just to drive people like that crazy. Also regularly referred to charts as 'sea maps', 'water maps' or whatever else would drive the NavO nuts
To be a real pedant though, the Canadian legislation for the ColRegs includes the phrase below in the definition (and likely in the ColRegs themselves, but can't find a convenient online source for them):
"The term “vessels restricted in their ability to manoeuvre” shall include but not be limited to:"
So for example, if you have some limited steering for whatever reason, the CO may decide to indicate with the appropriate shapes/lights so other ships are aware. The list are times where you shall use them, but as always, use common sense. Practical scenarios may include something like steering by main engines, or some kind of hydraulic limitations resulting in slower turning/less helm available (have seen both).
Usually MARS pedants lose to Sea Nerd pedants; I've sat enough NOPQ boards that I read the rules myself to figure out the intent and not be bored out of my mind until they got to the interesting bit with the engineering systems.

Didn't realize you wanted the info for painting purposes.
You can ignore most of what you read above. The only important thing is what Humphrey Bogart ultimately gave you: Flag Hotel (square flag, three feet by three feet, split in two halves vertically, left half white, right half red) on the port side outer yardarm, the RAM shapes (three shapes about 2 feet in size separated by three feet, upper most and lowest most are balls, the middle one is diamond shape - basically two cones connected at their base - all shapes are black) at the starboard outer yardarm.
Don't forget that at sea, we fly our national ensign at the gaff, not the stern (the gaff is the little yardarm that is sticking out at 45 degrees towards the back of the ship at about two-thirds of the way up the mast. Our ensign is three feet by six, all white with the Canadian flag in the upper left quarter and with the navy blue RCN pattern fouled anchor with an eagle superimposed centered in the right hand white field.
Good luck with your painting.
