New Providence Island
Nico and I spent the last 48 hours crossing two completely opposite bodies of water. We left Gun Key, about 12 miles south of Bimini, on Friday morning and crossed the Great Bahama Bank towards New Providence Island. It was a 60-mile trip and the entire time we were in eight to twelve feet of water! We were glad it was high tide when we crossed several shoals. And yet, small Bahamian freighters make the crossing regularly. The bottom was mostly a thin layer of sand covering hard limestone. There were occasional sponges, sea fans, and grass. I saw one tiny fish swimming alongside the boat in the clear, clear water and later two dolphins swam under my feet as I stood on the bowsprit. But that was it for wildlife. We towed a lure the entire time and didn't catch a thing. The water was a brilliant turquoise. Near sunset, we needed to anchor so we hunted for a sandy spot near a shoal and anchored in the middle of nowhere. You could not see land and yet we were in nine feet of water. We weren't the only boats to do so in that area since it was several hours to the nearest islands and it is a busy route. The weather was calm (we knew we wouldn't be doing this crossing unless it was) and we spent a peaceful night.
The next day we started before dawn and went through the Northwest Channel between the shoals of Andros and those of the Berry Islands. Within a quarter of a mile, the depth dropped to 500 feet and within a mile, it was 2,000 feet! This is the northern part of the Tongue of the Ocean which gets to over 10,000 feet deep surrounded by all these shallows. The Bahamas look incredible from space because of this. The water changed to the same azure blue as the Gulf Stream. The Tongue of the Ocean was caused by erosion during a time of lower sea level. I tried to understand the scientific explanation but I can't quite figure it out.
The Tongue of the Ocean is nearly "landlocked" by these shallows, yet it is so deep, and it is around 90 by 20 miles. The U.S. Navy has long used it for submarine exercises, I assume because the Tongue can be made secure from Russian submarines that would love to observe those exercises.
As we approached New Providence Island, where Nassau is, the color changed abruptly from deep blue to green-blue to bright turquoise. We anchored in Clifton Harbor off Lyford Cay where we are now enjoying a rum drink and watching the sunset. But no fish.
A cold front is supposed to pass through tonight, bringing fresh northeast breezes for our passage to the northern Exumas tomorrow. The frontal passage is forecast to be benign, but we took special care anchoring all the same. On the south shore of this bay, we can see a sailboat similar to ours, cast up on the hard coral rocks. Just last week this yacht dragged anchor and wrecked in a frontal passage.

The chart plotter shows where we spent the night. We had to backtrack a bit because we couldn't find good holding where we planned on anchoring initially.
Look at the change in depths!

You can see the grass under the boat. I snorkeled around an saw some tiny conch and a large hermit crab in a conch shell.
Did I mention the water is 80 degrees?
