Channel & lake
Straits currents
Strong reversing E↔W currents run through the Straits — a wind blowing against the current stacks up steeper, shorter chop. Time your passage with the flow. (Live current speed, from the GLOS 45175 ADCP, is seasonal and often offline.)

Accuracy
Calibrating. Blue Wake logs each day's call and grades it against what the buoy actually did the next day; the honesty stat appears once a few days have been graded.
