I've bought ten new sailboats over the years. It is an interesting process. Much will depend upon the shipyard that will unload the boat off the truck and then put it together--commissioning. If it is a good yard, they will have specialist in rigging, engines, bottom paint and then checking out the all the systems (fuel, propane, refrig, etc.)
The supervision of the yard should be done by the dealer although I have found that I have had to keep tabs on things as well. My last boat was painted with the wrong bottom paint, although in the ordering list, we specified certain types of paint. We caught that in time.
But no matter how good the shipyard and how good the dealer some problems will slip through the cracks. It took me three years to solve a problem on my present (new) Hunter 27. The main sail was incorrectly cut and no one could figure out the problem. It's fixed now but somethings take time.
Some of the problems were of my own making. This time I order a radio that was too big for the navigation locker panel. We had to send that back and get a smaller VHF radio. My point being that there will be some slippage here and there. Don't loose your cool. And be prepared to wait. Shipyards will do something on your boat and then move their workers to another project. On our last commissioning it took the shipyard one week to install the wheel, not the pedestal, just the wheel. They probably won't work steadily on your boat which will drive you crazy as it did me.
But the end result I have found is that your systems (wiring, electronics, tankage, cooking, etc.) will be up to date and meet the latest codes. I've had a certified marine electrician say that Hunter does the best wiring of all boats.
Some suggestions: buy a three blade Max prop. I've had them on the last three boats. Standard gear for Swans and Oyster boats. You'll love it. Get companionway doors from this site from Creative Concepts. And if your wife likes to sail, up size the winches. She love you.
By the way, if you decide to sell the boat sometime in the future, you'll find you will probably get much of your money back. I bought a new Hunter 380 for $129.000 in 1999 and sold it in 2008 for $121,000. I wish you well. Enjoy.
