I’ve got a skiff on a slip in a tight marina, and when the ebb fully hits it’s all rocks and rip-rap underneath the boat. This is especially true in the extreme negative tides of the new and full moon. Unlike the east coast which has fairly equal tides, here it’s one high high and one low low, with one lower high, and one higher low each day. Mixed diurnal. A range about fifteen feet, with maximal ebb three feet below nominal sea level. So getting in and out, timing is everything, conditions and weather notwithstanding.
But I’m not just watching the water in port. My ongoing study, more practical than academic, how water and currents move. Specifically, about twenty billion gallons. Today was breathless calm, perfect for feeling the tide. I snuck out at daybreak in the peak of ebbing, a few hours before slack, all that liquid mass rushing out to sea. Drifting with this, I was pulled seaward around 2.5 miles an hour. Do nothing- row, sail, or motor- and I’d be gone in no time.
