Up and down the AICW, it was more than a half dozen that had conflicting data ad at least a dozen with missing signs when I was going through them.
When Garmin bought Active Captain I stopped using it, but when I was...there were still some with conflicting info and like many boaters input, I would have only trusted a few and even then, without good "current tide" info... some were still too close to call.
Did I manage to not hit any? yes...
Did I have it out with a few tenders? yes...after getting threatened or spoke to poorly.
Did I have to resolve these kinds of issues while an active duty Coastie? yes...I get both sides so I know what can and should be done with markings, standardization and smacking down of impolite employees or supporting them when they are correct and only slightly impolite when the boater is out of control...
