Check out a company called sailingholidays.com
They are based mostly in Greece
and do flotilla & bareboat
If you don't have any or little experience and your partner less so, I would recommend a flotilla holiday for boosting your confidence.
You'll have lots of good advice, help and backup if you have any problems and it's up to you if you want to join the rest of the group in the evenings.
The days are all yours and you can sail off for one night or so by yourself if you feel the need.
I cannot recommend the company or the holiday highly enough and I'm not connected in any way to it.
It's a great way to bump up your skills and continue to learn as there's something new everyday. An added bonus is the Greek & Croatian backdrop, some stunningly pretty places.
