Meng_Tze:Also, there is no standard in color and what each means. Even though there are many ideas out there. Yellow can be seen far better than orange. If you have to send up a message, do that with a slate or something. It becomes confusing to many boats if there are several smb's in the water and each has a different 'status' based on color. SMB only means that a diver is below. On most charters this should suffice.
I dunno, the british standard is orange=all fine - the skipper will already know your runtime anyway - one bag per diver, all named, yellow=problem and will involve a response usually a spare 21m deco cylinder immediately, followed by a diver - dead simple
When it's all gone horribly wrong, you need a quick, no brains response, you probably won't have time to write an epistle with cold hands on a slate you've dug out from the bottom of a pocket
