Hiya, thanks for contributing to OpenStreetMap. Are these racing markers permanent, or are they for a specific event?

If they’re permanent, are they buoys? If so they may be better off tagged as seamark:buoy_special_purpose:category=racing (see https://wiki.openstreetmap.org/wiki/Tag:seamark:buoy_special_purpose:category%3Dracing and related pages). The tagging scheme is a little complex, so I can help change the tagging if you wish.

If they’re not permanent, or are not physically marked, they probably don’t belong in OpenStreetMap — see https://wiki.openstreetmap.org/wiki/Verifiability

Thanks :)
