Untitled[edit]

I have taken a photo of the only place I have ever seen a full set of 4 cardinal buoys. Would it be useful in this article? See:

I have a bunch of shots, taken the same day, none great, which include the 3 spliced to make this image, which I could also make available. KenWalker | Talk 01:58, 22 October 2006 (UTC)[reply]

East and west configurations arbitrary?[edit]

I'm not so sure. Think of sunrise and sunset reflecting off the ocean. A sunrise reflected off the ocean looks like the Sun and its reflection moving away from each other. The Sun rises in the east, so the two arrows pointing away from each other indicate "east". Same with the sunset, where you have the Sun and its reflection moving toward each other, and the Sun sets in the west, so that's how you know that the two arrows pointing toward each other indicate "west". -- Denelson 83 00:40, 2 December 2008 (UTC)[reply]

Another way to remember it: the two cones pointing apart look like a Greek letter E/epsilon. The two cones pointing together look like a letter W on its side. Haven't got a reference beyond how it was explained by the mate mid-channel! Martin of Sheffield (talk) 16:42, 31 May 2016 (UTC)[reply]

Found some references. I've added then and rejigged the whole page. Martin of Sheffield (talk) 14:33, 24 December 2017 (UTC)[reply]

Well, that's useful for those who write their languages with the Latin alphabet, but what about for, say, Russian or Chinese mariners? I think the sunrise/sunset association for east and west is more natural and language-neutral, and allows you to actually read those topmarks rather than have to memorize them by rote. -- Denelson 83 06:25, 15 September 2020 (UTC)[reply]

This is the English Wikipedia and the Latin alphabet is (AFAIK) always used to write English. Martin of Sheffield (talk) 08:02, 15 September 2020 (UTC)[reply]
