. . . and what will you do the next day?
Seriously though, this has the makings of a really good week or two of leisurely and interesting cruising.
I'm not sure that I would bother with Boulogne, unless you have a pressing need to start from Ramsgate. I would go for a Solent or Brighton start personally.
For a first channel crossing, Solent to Cherbourg is easy as the route planning is simple (no traffic separation lanes) and Cherbourg is a huge target easy to enter in all conditions. It's obviously longer than Ramsgate-Boulogne but that needn't be a problem.
I don't know Courseilles or Grandcamp Maisy, but the others are all good. St Vaast is worth an overnight stop for good food and drink too.
Fecamp is worth going to; it's got all tides access and a tour of the Benedictine factory is compulsory (along with a bit of sampling!).
This is a good cruising ground, with plenty of options in easy range. A couple of years ago we did a St Vaast to Fecamp for lunch, then back along the Normandy beaches -- as a day trip, which gives an indication of how far you can get without too much trouble!
How about Solent-Cherbourg then along the coast to Fecamp over a few days stopping along the way, then Fecamp to Brighton, then home? That gives all the stops you want, plus a couple of decent offshore passages.
