Thanks Wayne. I found the symbols on a Nautical Chart called Chart 1. it explains everything about navigation. And it was Bo not Bd. Memory must be going.... Which of course is boulders.

Just curious if anyone knows what all the letter symbols on the Hotmaps charts mean. For example, I routinely see " Cb " on the map, or an " M " and I think " Bd" I always assumed that M was mud, Bd was boulder, but I am not sure. And I do not have any idea what Cb would be? Thanks
