Back to your sea trials vs real life use and original post. I can easily imagine a used boat, not much use lately, sitting with a for sale sign on it, going off for a trial and selling. Then after a couple of fishing trips, pot holes, waves, rocking; the sediment in the tanks getting tossed up in the fuel. Not a big woo, just an extra adventure and hit to the purse. You, I and hopefully others have learned something extra.
