The only person on this site with any DS sailing is Zanshin. If you go to this link
is a list of 42DS owners on the Jeannea owners site. or try posting your question here
on the forum part of that site. Then you will hopefully get some answers from folks that "HAVE" sailed the boat.
BUT, if you are seeing and reading those comments from sailing mags, more than likely they are true. There was a thread re this exact issue on some of the newer Jeanneau designs, not just the DS models. One fellow reported it with a 32i and the newest 30i's too IIRC.
