They might also enjoy [[Breathing Underwater by Julia Green]], which is also about change in many ways. It has slightly less of the supernatural, but the sailing and naturalism is similar, as are childhood worries about parents breaking up. [[Waterslain Angels by Kevin Crossley-Holland]] is a wonderful and slightly supernatural story set in the 1950s, which I think may also appeal.
