Kayak visibility is a safety issue.

[dwest]

At night there are navigation and running lights, and SOLAS tape, to consider. Maybe a radar reflector. Anything else?

In daylight there are kayak flags, outerwear in safety orange. Anything else? Other colors?

When efforts at visibility fail, there are last resort sound signals: whistles, air horns, etc. Anything else?

Thanks for your thoughts
