This question is debatable and dependent on whom are you asking. If one was to query our 12 year old daughter, she would promptly tell you that a boat hour is about 4 hours. Unfortunately on more than one occasion she has been with us when we have said, "We just have to run to the boat real fast. It should only take an hour." Initially, she is not bothered until the hours start to peel away. She is very patient and only after she has picked up much of the debris around the boat and turned into some sort of art, walked the dog a few times, ate her snack, and played on the smart phone does she begin to protest. As parents whose time is continually being squeezed between work, daily grind and boat preparation, our need to "finish" our "quick" project supersedes her protests. With promises of dinner, we usually can persuade her for another hour, then promises of dessert for another. We know things have hit the fan when we start promising staying up late, junk food or some other contraband that is typically not allowed.
We are appreciative of her patience which reminds us of the sacrifice that we all are making to have this plan come to fruition.
