as a third party member who isn't married nor have kids- and therefore, my judgment isn't clouded by emotions - I'm more inclined to side with the husband. Your son is 18 yrs old. He is an adult by law. Had the boat belonged to a stranger, your son would either be in jail or getting sued. Since I know he doesn't have $16,000, guess whose pocket the money would come from? Be thankful the worst that happened to him is he got kicked out of the house.
