Not an owner, but have been impressed by the relative good condition of s2''s that I''ve seen. They seem to stand up well to usage that would make other boats shabby quite quickly. I''ve seen several different models and was impressed by the small amount of spider cracks, crazing, or even dings in the decks & cabins of boats that were certainly old enough (8-12 yrs) to have their share. They seem to have been built matter-of-factly, using things that work.
Some of them have reputations for being pretty quick, too.
