"Every now and then I read something about the decline in sailing. Part of the decline I read about is attributed to the increasing cost of keeping a sailboat. That brings up the question - How much does it cost you to keep your boat?"

Perhaps he is interested in the link the cost of boat ownership and what he has read about is the decline of sailing. That's why "anyone even cares"? It's not just about what you care about. He asks a very salient question in my opinion. Sadly, many people, young and older, cannot contemplate recreational boat ownership because of the increasingly high costs associated with it, not to mention the great difficulty of obtaining a slip in some areas (where there are no moorings).
