Hi folks, Diana and I transited Hell Gate last week and made up a screenshot with depth annotations. Figure this may be useful to anyone else headed through there soon. https://www.facebook.com/notes/on-the-water-chartguides/hell-gate-a-quick-reading-on-one-of-georgias-shallower-spots/378960472153535 or http://on.fb.me/Ny8jhN We'll try and write up more of the known trouble spots as we head north. Best, Mark www.OnTheWaterChartGuides.com (formerly Managing the Waterway)
