Nice boats. Lots of room, well laid out, very pleasant to sail
I looked at one fairly seriously when I couldn't find the Ericson I really wanted. The thing that ultimately made me walk away was core issues in the topsides - the seller (apparently well into his 80s) had adopted a docking-by-braille approach to getting back in his slip, and there were multiple places where the outer skin had cracked and allowed water into the core. That plus a number of dead-spots in the cored deckIt was more than I wanted to take on.
Other than that, it was a fairly typical 1980s boat with all the typical needs - needed some upgrades, some re-wiring, some re-plumbing, and a fair amount of deferred TLC.
If I'd found one without core issues, I'd probably be posting on the C&C list instead of the Ericson forums these days...
