As we sailed back at around 4:00 p.m., the wind was behind us. The tide was with us also, so with only the jib on, we arrived back quickly. I find tides to be fascinating movements. Rachel Carson’s chapter on "Tides" in her book, The Sea Around Us (1951), provides an eloquent description of tides and their connections with the moon, currents, flora and fauna in the sea, and yes, sailboat movements. In 1962, she published, Silent Spring, where way ahead of her time, she denounced the future impact of industrial waste. Industry and government, with the help of prominent male scientists accused her as a crackpot, a modern day witch-hunt. If we had only listened. Now Rachel Carson (1907-1964) is revered as a great writer, ecologist, and scientist (see picture below). She has more books, though I highly recommend the two I mention. They are very well written, which makes for enjoyable reading, and they are still informative.
Tides are like the planet Earth’s breathing in and out. Tides in the tropics are smaller than at higher latitudes. They usually average one foot high or low. No dramatic Bay of Fundy here. The tropical tides on the east side of Puerto Rico are easy to follow. They ebb north and flood south. If one looks at the current, without consulting a tides table, it is possible to determine the tide. We flooded right into the marina with the tide. Freedom!
