Hobie Cat weighs the hulls and marks (engraves) them prior to shipping. I'm not sure whether any attempt is made at matching heavier hulls to lighter components for the rest of the boat to keep the weight at or near minimum.

The average weight of a single H16 hull is around 70 lbs. A light hull is 68 lbs or less, heavy is 72 or higher. These are rough numbers, working off my last 3 new boats since 1997, and comparing to others over a beer.
