- - Look at the definitions in Chart 1 and you will see that overhead obstructions are charted at high water
while underwater obstructions are charted at Low water
. And the charted height is only measured where it crosses a channel, not elsewhere along the cables
, etc. - same for bridges.
- - That said, it does not mean that over the years there may be additional "droop" in the cables
making the chart's shown height obsolete. These items are not updated.
- - There are high tension lines in the Cocoa, Fl village anchorage dividing the north anchorage from the south. Some boats have dragged anchor
into the power lines with spectacular fireworks show results. I never anchor
"upwind" of power lines.
