Actually, I care because it means there are up to five year waiting lists to get a berth at a marina of 500 boats, even though fully half of them are not actually used or sailed as boats.
I care because prices for places to park and store your boat have sky-rocketed into the ridiculous.
I care because the few clubs out there that are "all about sailing" are having their rates and taxes jacked up by local city councils who want to get rid of them and replace them with more profitable huge marina developments which will be full of yet more expensive stand-still yachts that never leave and clubs, and bars that more closely resemble casinos then club rooms where sailor's can gather after a race.
I care because when you are interviewing someone for crew and they used to say "My dad has always owned a boat" it meant that it was used as a boat and the guy's kids probably knew how to sail...Now it may well mean that the guy screams "what the f*ck is that?" when you first hoist a sail.
