I like to view today, tomorrow and the next day, since I am often
considering whether tides+currents will make a site better or worse
in the next few days in my sailing decisions.

No, I just use the data from the program.

Coyote can be sailed at any depth.

3rd has some sandbars as high as +1.0 ft, so I call it "safe" at +2.5
ft. I sail down to 1.5 ft with caution and sometimes even 1.0 feet for
launching or returning only. Others have different caution levels.

It would be nice to add a chart for Palo Alto since the tide is nearly
an hour later than 3rd; this has a safe level of 4 feet (similarly

I also find it very helpful (in another tide program I use) to have
markers set at 2:00 and 6:00 - the normal Peninsula sailing hours.
