How closely do the GPS plotted positions match, last time I was there I did not have a chart plotter.
Thanks...Ix
I forgot to answer the above. I'm feeling a lot better about reading the water and as you know that is the first means to keep you out of trouble and not what the chart plotter says. I plot out each move and have the points also in the handheld and use it 90% of the time but keep peeking at the large screen (chartplotter) in the companion way to see if I'm in an area where the channel is real narrow and there might be very shallow water on one side or the other or coral heads. If so then I really try and hit my marks but what the water color tells me is the final factor in hitting those marks or not. None of these charts are that perfect or that accurate.
I plotted the course from Rudder Cut to here (Little Farmers) on a large scale NV digital chart that showed the entire route in detail. There was still a larger scale chart of just the harbor here at Little Farmers. When I switch up to it some of the waypoints I had plotted showed up on top of areas with coral heads so I moved them before I downloaded them into the hand held. When I got here I used them but mainly used my eyes.
I would not want to come into these anchorages at night on waypoints alone since no the charts are not perfect. Everyone says that Explorer Charts are the gold standard and I have them and like them but they are paper only since the digital ones won't work with OpenCPN and the paper doesn't have the detail that the NV digital I'm using have. I think I also have read, this might not be right so check it out, that Garmin now might not be using Explorer in all cases for over here. The Explorer Charts themselves say there could be errors so as you told me use any of this to get you close and from point A to B but your eyes are the final factor. One thing about the Explore Charts is they also have a lot, a lot, of other good info along with tide tables which for sure you need also THE YACHTSMAN'S GUIDE TO THE BAHAMAS, recommended by Mike, is also a good guide to have and also has the tide tables.
Yesterday...
.... I was going to take the 'safe' way, left arrows, vs. the dinghy channel right arrow since it shows depths of under 3 feet at the point of the arrow. When I got close I changed my mind as we were going to high tide and looking over there it looked doable so at the last minute diverted towards the dinghy passage figuring I could change my mind at the last moment. At the same time I had a large motor yacht right behind me a ways and I'll bet they wonder what I was doing as the made their turn to port on the route that I was going to use.
I got to the passage and the water looked good, shallow but good, not white. I went through and it got shallow enough that it kicked the rudder up, so it was probably a tad under 3 feet but it immediately increased in depth. When the rudder kicked I just steered with the outboard for a hundred feet or so and then was able to pull the rudder back down. Looking above it looks like I went over the end of the bar but at the moment where I went was the deepest water available.
Also the references I mentioned above have color pictures on reading water depth that are good for anyone that hasn't been over here,
