Dougal Robertson

Jack and Claire Carpenter realize his life-long dream by selling the family farm and uprooting their four kids to buy the yacht Providence. Shortly after sighting whales, they are hit by a group and sink. Their inflatable raft is too small for six people and supplies are only for a day or three. To get 1,000 miles further, where sea traffic is far more likely to find them, Jack designs a sail. Everything proves hard, but the boys show great courage. (imdb)
