As of December 1, the United States Coast Guard’s calculated vessel capacity has changed. Why? Apparently, because we have changed. Since 1960, the USCG has calculated a vessel’s capacity based on an average weight of 160 pounds for each individual. That average weight has now changed to 185 pounds, and with it, so has the capacity of vessels. So make sure you recalculate your boat’s capacity before heading out for your next sunset harbor cruise.
