Welcome Penny, I have meet many cruising familys and even married into one! My father in law put three kids
(10 and up) and a dog on a boat and did not come back for almost 10 years. My wife is not a great speller but more than makes up for it in common sense.
I think you should tell hubby to clip his wings for a while and take junior cruising. He will want to leave the nest soon enough so do it while you can. Good Pilots can always get a ride.
MIddle and High Scools are nearly useless for real learning
and are breeding grounds for bad behavior. Long days at sea are great for hitting the books
and you all will be much closer for the experience. Even a year will change him for the better.
Then again he could end up a boat bum like us.... perhaps we are too hasty!
