No, it depends on the age and state of the boat and its size. A boat with all original equipment will appear to fall apart faster than a boat that has a) been maintained, and b) been upgraded.
My older boat is 35 years old, and so is the engine. But after lots of niggling problems, I rebuilt the engine in 2005 for about $1,200, replaced the ENTIRE fuel system (vent hose...BIGGER, new gasket for the fuel fill, new fill hose, new fuel line to a shut off then to a spin on fuel-water filter, a new exhaust hose, a new Vetus water lock muffler and new post-lock exhaust hose (with a proper riser at the stern).
The cost of all those "extras"? About six hundred bucks. The result? Never a drop of water in the oil...instant starts, better fuel economy, "clear" exhaust and a general sense of confidence in propulsion.
It's clear that the original electrical system is pretty well shot, but that's a different job. I can display enough lights to make it legal.
Now, a "surprise" this year is some sort of crack in the keel-hull joint or the wearing out of some ancient repair. I have some water leaking in, but the current "steward" of the boat bought a sausage-sized bilge pump and it's keeping the ten litres of ingress a week under full control. So I'll have to address this at haul-out.
And my recut racing main finally died after five years of abuse...but it cost me 200 bucks and I had a spare Dacron in great shape, so that's no issue.
My other boat is being drastically altered for world cruising, so that doesn't count, but I would say that if your club costs at the 30 foot range are say, $3,000/year all in, and insurance is a tenth that, if you budget $1,000/year, you'll have a nice boat. If you don't race, you can get 15 years out of a dacron set of sails, and if you're like me and scavenge from racers, you "recycle" sails for $100-200 each and use 'em until they are done (three-five years). A recut race sail for me is going to be better for two years than a brand-new Dacron "cruising" sail because of the typically light air.
If you are in salt water, your rigging will last maybe 20 years if you are fastidious...that's a big expense, but worth it.
