I can only assume that the glue that holds this list together is your price range. Of the list, the Pearson 30 probably offers the best combination of accomodations and sailing ability. The S2 26 is probably an 8.0 which was a miserable little boat on all counts. The Pearson 26's are very nice boats in a lot of ways but they are known for keelbolt and keel connection problems and so if they have not had the remedial work done, I would take them off your list. I think that the Morgan 24 was out of production by 1977 so I am not sure what boat this is but the older 1960's era Morgan 24 is one of my favorites from that era. While not as roomy or offering as the same performance as many later designs, these boats sailed quite well.
