For anchoring, I really like the idea of a low-mounted anchor light instead of the masthead light (which I have now). Fast-moving small boats speeding around anchorages are more likely to see a light mounted down low. I have a couple of those solar lights I keep on deck but they are not very bright. The boats I see with low anchor lights are much more visible from deck level. Having a separate, hoisted anchor light may give you more options.
