Flag?

[Spiderman]

My Christmas stocking this year contained a nice new float from Omer which will replace a really bad scuba diver's one I bought 18 months ago from ebay. It comes with a white striped red flag which I belive to be the international "diver down" flag. I have also seen dive boats using a blue and white "A flag". Which is the right one for UK waters, and where can I get hold of a blue one if that is what I need? Any tips for making your own?

the blue and white one is the new international divers down flag, we dont use em down here yet, so i use a red one... not sure which one is right for UK waters but we have enough uk spearos on here to tell u the right one to use

This is the official situation in the UK taken from this website

Diving operations are indicated by flying one of two nationally recognized "Diver Down" flags, or navigation lights if at night. Either signifies a danger area. Stay well clear of diving operations because divers can easily stray from the diving vessel. International Code Flag "A" has several uses, one of which is to designate diving operations. The Inland Rules specifically require a boat, when engaged in diving operations and thus restricted in its ability to maneuver, to display a rigid replica of the International Code Flag "A". Exhibiting this signal invokes a special right-of-way of this vessel over essentially all other vessels. The key point is restricted in the ability to maneuver.
Code Flag "A" is used only on a vessel. It should never be displayed on a diver's float, or raft.
However, it is the practice of nationals of other countries to use the Code Flag "A" instead of the flag shown below. If the Code Flag "A" is seen on a diver's float or raft it should be treated as meaning: Caution - Diver Down.
A red square flag with a diagonal white stripe is also an accepted and recognized signal meaning: Caution - Diver Down. This flag is used on a vessel or on a diver's float, buoy, or raft to indicate diving operations. When divers are swimming free of the vessel, this would be the logical flag to use. The flag should be exhibited in rigid form.

I've got the right flag then

Just need to make it rigid!

piece of stainless steel wire attatched to the flagpole, running diagonally across the flag, it may not be the perfect thing, but it keeps it open enough that nobody has an excuse not to see it
