Moorings boats go through a phase out refit. We bought a 2009 Oceanis 40 in 2014, the seller had purchased the boat on phase out from Moorings one year before for a family sabbatical. Moorings addressed all of their survey issues. Looking at their year-old survey and the survey we did one year later, it looked like Moorings had done a good job on phase out.
A year later, I'm happy with our boat. We've had to do the kind of maintenance and upgrades you expect on a six year old Beneteau.
Something to keep in mind is that the boats that moorings orders from the manufacturers may not be equipped the same as those sold by dealers. If you want to end up owning a standard production boat you need to go a different route.
