I spent a lot of time at that plant, as a supplier I did tech service for them, I would also periodically do multi week audits of the production process (this was years ago). The VEC plant was very impressive for the time, it was designed more like an automotive production line than a typical boat building shop, very clean, well lit, no odor and automated where possible. The biggest problem they ran into was that they could build far more hulls than could be sold, 3-4 hulls could be built an hour, hard to sell that many a day, every day, month after month.
Normal production is very dependent on the skill and attention to detail of the person actually working on that hull, so the quality could vary a great deal from boat to boat. The VEC system was very repeatable, so if you get it "right" it's more likely to be "right" every time, but if you get something wrong, then every hull is wrong until you find out and fix it, which takes time, since the VEC method was new it took a little while to dial everything in.
