I'm not talking about swiss family robinson. this movie probably came out in the late 80's early 90's. it's a family of 4, and i think there boat wrecks so they become stranded.They build a huge tree house, and make electricity with a water wheel that they clean there shoes on.The daughter of the family falls in love with someone that lives on the island.Towards the end of the movie pirates come and try to attack them but they have these boobie traps set up to stop them.And then they finally get off the island because their son wind surfs to find help. ring a bell with anyone??
