Secondary Ports Calculation

[andrewsterling222@hotmail]

Hello all,

Just teaching myself tidal calculations in secondary Ports. Quick question - when including the difference in time between main ports to secondary, if it's + 0105 to + 0005, would that mean there's 1 hr between the two, or is that 100mins(1hr and 40mins) ??

1 hour, not 100 minutes.

0105 means hour and 5 minutes (and not 105 minutes); 0005 means 5 minutes

That's great. Thanks for your help jfm.
