Our Delmarva Grady White Club did a factory tour past May, and we split into several groups and walked the entire facility. They encouraged us to stop and talk with any worker even while doing their job, and ask them any questions we might have. This was the 5th factory tour that my wife and I did, over the last 33 years.
I usually ask several employees how long they have worked for GW, and would they do it again. So many have been there 12, 20, 24 years, and they smile and say best job ever. They are team workers. Grady tells us take all the pictures we want. No areas off-limits. How many boat manuf's allow pictures, if they even allow you on the production floor?
Grady pays bonus money to employees, for ideas that can be used to address production problems or improve Grady quality. They also pay employees who will take home and read books from the Grady library, motivational /self-improvement type of books. $45 to $95 for every book they read. There are no tests; it is the honor system. It must be working; they've been doing this for many many years. There's so much more they do for their employees; it is unbelievable. What other boat builders do these kinds of things?
I wouldn't be too concerned about QC, and if you can make the trip the Greenville NC, you should go see your boat as it's being built, tour the factory and come away with answers to your questions.
