Honestly, I dont know. In my eyes I dont see a production line sending boats back and forth to repeat stations but who knows. Plus theyve already put the tank in so you cant glass over the fill line and theyve painted the bilge and gas hose area and filled all the other voids in the boxes over the stringer system. I think yall think I'm saying they build a junk boat or something and that's not what I'm saying at all. Theres just one aspect that I personally dont like and that's just my opinion. I dont own one but was really interested until I was in one and I had seen this pic before hand and it wouldn't have deterred me from getting one. Now, I would say if I was to order one it would be a question I would get answered just for piece of mind. They are nice boats, theres no doubt about that
