Sorry to disagree with many here but I do NOT think that this reef is well marked at all! They can and should do better so as to protect the reef. No one wants to run into a reef and I've always been surprised that at how it is marked. It should be marked so that in inclement weather and in calm weather (I have often seen it without any breaking water) the markers are well visible. By the way we live in the USVI on our sailboat so we are not casual or inexperienced boaters.
