A few other items I noticed.
1) The water fill has been moved back about 4". Now it is just behind the bulkhead instead of just in front of the little step up on the walkway. The step up is designed so that when water runs back along the edges of the cabin on the walk way, it hit the step up and rolls off the side instead of into the cockpit. With the water fill just in front of it, water could gather there. If the fill tube wasn't sealed properly, water could run inside the cabin. That was the source of a leak on my boat just after delivery and it took me a long time to figure it out. Apparently Scott could see it coming and without ever having been aware of such a problem having occurred, fixed it for all future CD 22 owner.
2) The bilge has been permanently moved to a bilge well in the aft end (where it belongs). The bilge pump has been upgraded to a Rule 2000. Good move.
3) The bottom of the fiberglass below the gunnels and wrapping around to under the transom is now finished with a nice aluminum edge (instead of the black plastic edging. Much nice look.
4) As Mark noted the corners and the termination on all the rub rails are now nice stainless pieces. Very solid and MUCH nicer looking.
5) Under the trademark C-Dory stripe, the factory has added a thin color contrasting pin-stripe. It really brightens up the look. It looked very cool to me.
6) The doors on the cabinetry are now standard as teak doors. Much nicer.
7) The boats are now all equipped with a standard wiring harness that hooks to a "dealer bus". Dealers are now (or soon will be) supplied with a standardized and recommended wiring diagram. That will make the boats more standardized and much easier to trouble shoot in the future.
I'm sure there are dozens of other little things I didn't notice but the key thing to me was that many of the little annoying things that a real BOATER would recognize as a problem or an annoyance are fixed in the newer builds. That's because Scott who oversees the builds IS A REAL BOATER. He's been on boats since he was a kid and spent many years working as a commercial fisherman. So he's not just a boat builder, he's a life long boater and he knows what is right and what will be annoying in the future. He can and does change the designs and builds to take care of all those small things.
I also had a nice talk with Scott after the class. He's acutely aware of the benefits that the factory gets buy selling direct and/or repairing what they built (and what the previous factories built). This allows him and the other builders to see and "own" the problems in the design. This in turn results in design changes to reduce the problems. As long as the factory stays engaged at this level, the designs will rapidly improve and ultimately will approach perfection.
I'm certain there are dozens of other minor changes to the 22 that Scott has made that I didn't notice. However, all the changes that I did notice were quite clever and will only improve the boat. Based on that, I think the line is in good hands.
