Hi!
Rookie question. Experienced of sailing in the Baltic Sea. Took courses in tidal sailing (theory) before departing on a cross-Atlantic voyage. Currently in Ooestende, crossing to Dover soon. Please look at this picture from our pilot book "The Shell Channel Pilot" by Tom Cunciiffe.
I understand this, if I was navigating with charts, old-fashioned way. However we are also using the plotter and the Navionics app. We roughly do like this in harbour:
1. Check Reeds.
2. Verify in Navionis app.
3. Talk to other sailors, it seems wise to leave when others do.
However we will have stream both ways on this 60 Nm passage, so one guy said it's unnecessary to do the math + Dover is an all-tide harbour.
Of course winds needs to be checked etc, just considering the tidal part here.
My question:
We got a Raymarine ES75 with Navionics Gold charts for Europe, a few years old. There is tidal info in the charts, I have turned on the blue tidal arrow on the boat icon, you can click on stream and tidal icons and animate etc. Useful.
If I make a waypoint at Dover, will Raymarine do the best route as described in Mr Cuncliff's book (see image)?
When sailing over the Baltic Sea, the plotter does indeed take drift into account, so I do get the shortest route when sailing towards a waypoint on the other side of the Sea using the Autopilot. Will it do this also in this tidal scenario when facing different currents for the whole passage?
Cheers
