Kenneth was just remarking that it's probably not "OK" to buy a boat that can't go sailing in big wind.
Boat purchase advice, especially for Ericson family boats, is one of the best features of this site. The more information a prospective buyer can provide, the fuller the responses--all from brand owners. At the moment you haven't shared enough information to fully exploit us. That would include full inventory, and current age of inventory items. The design is well known, what is not is the condition of cushions, sole, outboard, dinghy, decks, gelcoat, electronics, canvas and all the other details upon which price is negotiated. it is from such lists that others here can make money value judgements, and give opinions.
Actually, though, it is unlikely to find any boat of this vintage in 'turn-key' condition. Every Ericson is an old boat, and every one requires replacement of gear--continuously, and forever.
Also, in many such threads, the decision on a decent candidate boat really comes down to whether you want it or not. There are many boats on the market. if you like a specific boat, and want to own it, buy it. The current owner probably has learned the economic reality, but he also has to want to sell it. If he doesn't, move on.
but the actual purchase price hardly matters. Any disagreement will be in a range such that the difference between bid and asking is trivial compared the expenses that lie ahead. Ericsons appear to be a bargain at 30-60K for a big yacht that can cruise effectively and even cross oceans.
They're not bargains. They all require enormous attention, time, commitment and money. And an absolute necessity to be happy with tools and sweat.
