I am going to Guernsey on Saturday and staying until Saturday 25th or Sunday 26th July.

I have left my tidal atlas on board which makes planning the approx departure time home very hard!

Can anyone either scan me a copy of them or tell me what time approx I have a favourable tide from St. Peter port either North or south around the Island. I will be heading for salcombe

Thanks in advance
 
I usually leave St Peter Port about 3 hours before HW at Dover. From my Atlas, that gives about 3 hours of Northerly-ish tides to get away from the Island.

Last time I left at 1015 hrs and arrived in Cawsand Bay at 0500 the next morning. Not bad for a 22 footer of 2 tons!
 
Looking at TotalTide, the Admiralty software, on the laptop sitting in a dreach Penzance, it looks like you could set off Nwards about breakfast time on the Sunday, 10.30 BST, pushing a kt of foul tide for a while. You'll be 7 days before springs.

Blooming Nora! SPP to Dartmouth usually takes me 11.5 hours! What are you sailing, a foiling Moth or something? That must have been an AVERAGE of about 12kn! Congrats! Can I have some of what you're using?

Sorry, I don't follow you. 90 miles from St PP to Plymouth at 5 knots takes 18 hours. My quoted times means it took me about 19 hours. Top logged speed of 6.4 knots. St PP to Dartmouth is about 70 miles, so your speed is about 6 knots average and I expect your boat's bigger than mine:)

From the tidal stream atlases on visit my harbour ( link above in Yngmar's post) I would have said 4 hrs before HW dover to go N up the Little Russell and little later 3 or 2 hours before HW Dover to go around the south of the Island

I think you need to re-examine your maths 1015 to 0500 is 18¾ hours!

Mea culpa! Sorry, it was a long day and I made the (embarrassingly) basic error of seeing 1015 and interpreting it as 2215 in my enfeebled brain. What an eejit. Shows why it always pays to double check calcs, then check them again, in my case at least!

Still, you've got reason to be proud of that time, Appledore. Really excellent passage.:encouragement:

Thanks for that. You can buy me a beer the week after next if you are perhaps in Guernsey, or (I hope to be) in the Isles of Scilly, LOL!

If you have a Reed's Almanac, (either current or old), you will find a Tidal Stream Atlass in there.
