Maybe too great. Had a survey done today on a CS 36T. Structurally the boat is in very good shape, but lots of niggling and not so niggling things, a few of which must be taken care of and a longer list of stuff that should be taken care of. Mostly I was disappointed by auto-grade wiring terminals, strange plumbing and rat's nest arrangement of stuff in lockers, behind panels, etc. Lots of enthusiasm and creativity I suppose, but not necessarily appropriate for marine use, and if you didn't put it in poor you that has to figger the stuff
out. Even the surveyor was left scratching his head a few times.
Anyway, the surveyor figures it would take about ten grand to update stuff, and the boat is already on the high side of the price range for these models, (in part because of structural/mechanical upgrades done). Does that seem reasonable? Is there a general rule of thumb regarding what you should be looking at in costs AFTER you buy a used sailboat?
Honestly, I feel a little let down. Although it's necessary, taking apart a sailboat like this is like the difference between meeting a gorgeous woman on a smoky dance floor and seeing her the next morning under bright fluorescent lights.
