Hi, Alex V, and welcome aboard CF.
Under the Search menu, about 5 items down it, you will find the CF Custom
Google Search, it is good at turning a
concept into articles you can click on. The within-CF search is an exact match deal, and not well suited to
concept searches.
In addition, there's a recent new vs. used thread ongoing, and threads on the other concerns, except the Catalina vs.
Beneteau vs.
Bavaria. You could start a thread on that, yourself, but there's lots here for you to look at and consider. You will find that specific questions will bring more useful answers, compared to general questions.
Hope this helps.
Ann
