The penny is dropping ,
The one I have got is called tide planner which for me is quite easy to understand and your right you can move the vertical line across to see the depth at a given time . So now you have told me the depth I need at whitby it seems fairly straight forward .
The other good point about having this conversation mid week mid day is that hopefully there won't be to many signed in rolling around the floor laughing !!!
Thick question number two. The tide planner I mentioned does not seem to let me look forward past the day we are on . There is a date logo at the bottom but it won't let me change it . Is this something you have to pay for or is it just a case of altering my iPad settings somewhere ?
