We just had the same experience coming into the jetties at Freeport
The chemical plants have completely screwed up any hope of seeing the markers at the end of the jetties and to compound the problem the red light is on a 15sec flash which means when it goes out you have moved a fair piece before it flashes again so you lose it. The green however is a steady.
My first indication of the end of the jetties was looking to my right and seeing a fellow standing under the flashing red light fishing
Once in there is no turning back as they are quite narrow(and made of granite blocks). Thankfully there was no swell or wind
to contend with.
I try never to rely on my chartplotter but this time I was using SeaClear and the free NOAA charts
with the AIS
turned on as well. It wasn't just accurate it was dead on the numbers accurate. Us, as a little blue circle, were sailing right up the middle of the channel just like reality.
We weren't planning on a night time entry but there was just not enough wind
to get us there before dark and a tropical disturbance was starting to show signs of doing something a ways south of us.
It still took me about an hour to wind down from that entry..........m
