I have a 47 with teak decks, they were well maintained up until about 2 years before I bought it, it's a mixed bag. some leaks
but not a lot, more leaks
from the ports
than anything, something i'm getting after as we speak.
If it's had the teak decks removed it's less maintenance
and less of a wild card, I'm most likely removing mine.
They used copper for plumbing
so that is also a mixed bag, some in excellent shape some needs replacement due to chafing.
Look it over carefully, also take a good look at through hulls.
Chainplates are also an issue on Cheoy Lees overall, the quality of the original stainless is questionable, see if the originals have been replaced, if not, figure that into the price
. A decent metal house can make them for a reasonable cost, just make sure it's the correct grade of stainless. I'll be replacing mine before any serious travel is done.
Also look for any winches made by Cheoy Lee on the boat, you'll likely end up replacing those too.
