It may sound pointless or even counterproductive, but this morning I was looking at a chart and wondering about "Can we clear..." which always means manually looking at the tide and then compensating the tidal range into the charted depth
You know, if the chart says 5' clearance at MLW but there's a 6' tidal range and you'll be passing through at high tide, you've got 11' of depth
, not five. Make a mistake and you go crunch. (Knock wood
, not yet.)
Then I started to wonder, is there any modern software
that will display the official depths, with an option to CHANGE those based either on the current
time's predicted tidal range, or based on "You'll be there at ten o'clock and at that time the depth will be..."
Yeah, I know, plenty of room for liability issues and plenty of ways to get in trouble. But the thought occurred to me...I haven't seen this, and it would be SO easy to implement in chart programming, where depth information is just one more layer of discrete overlays.
