This is what me and the wife did.... and what we learned.
First, we did a one week skippered
charter in the
Ionian. We then completed a 5 day RYA Day Skipper (DS) course in tidal waters and converted that to an ICC. We also did the RYA
VHF SRO qualification. We did the theory sections of both courses on-line. Wherever you do your DS, do it in tidal waters. The qualification carries more weight when you bare-boat charter. The
Med is not tidal. the rest of the European coast is. You mention 'warm and sunny'. Try the Algarve or
Gibraltar.
We then joined the Cruising Association and the UK's Civil
Service Sailing Club and used their
crewing services to get 3 weeks of free and friendly time on experienced cruisers boats. After that we did a self sail flotilla week in the
Ionian immediately followed by a week bare boat around the same
route.... on the same boat.
We bought a 40ft
blue water boat in Lymington and set sail across the Channel to start a very slow
circumnavigation.
Prior to this we had no sailing experience.
In summary: You should get an ICC and
VHF SRO
license. These allow you to bare-boat charter and sail your own boat almost anywhere.
After the DS practical you won't learn much sailing in and out of a marina for a day. It's better (and more fun) to
passage make and spend days at a time
crewing on other peoples boats. We found the CA excellent for that.
The Comp Crew isn't worth considering. It doesn't add any value.
