Although I don't own the same boat, I do own a Beneteau. I have read this thread with interest. It seems to me that some of the blame for the boats' problems is misplaced. I would submit that a number of the issues are supplier related and not necessarily the builder's fault. An example of that is the sail drive problem. The electronics are another concern. If lightning is involved, they are definitely vulnerable. That may turn out to be exacerbated by a design issue and/or insufficient protection. After all, a mast can be a Significant lightning rod.
I know that I have mentioned it in another thread, but a mass produced boat is not built like a mass produced automobile, Its still pretty much of a one of a kind product. The work force building them is certainly not made up of master technicians for the most part. Subsequently things get out of the factory that should not.
Without a doubt, the builder is concerned because these issues impact it's reputation in the marketplace, and as the cliche goes, a dissatisfied customer will tell six of his friends, while a satisfied customer doesn't always say much. The dealer gets into the picture as a bad guy because he gets the heat for commissioning issues. some of those are real problems, others are quick fixes that some owners simply don't have the skills, ability, or patience to fix.
It would be interesting to get some direct feedback from Beneteau and the dealer organization in this forum regarding how they respond to these concerns...
The fact remains that boats are not a low cost purchase and the customer has every right to expect quality and reliability in return. Add to that the fact that in some cases lives might be dependent on those factors.
For the most part, discussions on this forum can be quite constructive, and if we can keep from shooting the messenger (and that does not seem be be happening here), a lot can be gained.
