C&C 40 or Soverel 41
Both of these are odd ducks. The C&C Crusader was a reasonably well constructed reasonably good sailing boat. I raced against one called ''Old Blue'' that did quite well under PHRF. They were at their best in moderate winds in races with ling beats and long downwind legs. They were designed at a time when C&C was a world class design firm but a lot has happened since that time. The Crusaders tended to be a little on the rolly side.
Soverels were extremely ideosyncratic boats. Build and finish quality varied depending on what part of the boat you were evaluating. They had quicky details and very simple layouts, rigs and engineering. They tended to have good ventilation and comfortable berths. They tended to rely on form stabilityt more than was popular at the time and so have slightly snappy motions.
Neither boat is much of an offshore cruiser and neither are very well suited to the lighter winds usch as are typically found along the center of US east coast. An example that was in good condition could go offshore, ideally picking its window, but these boats are somewhere between 35 and 40 years old and so would need a lot of attention from you or a prior owner if you planned to take one offshore for more than short hops.
