here is a plan
first: at quiet moments sit wistfully staring into space.... make sure she spots you and asks you waht you were doing.... thinking about sailing is the answer
second: buy sailing books from amazon for $1 each. Leave them around the house. read passages out. buy some childrens sailing books,read them to the children
third: watch sailing films on you tube with the volume turned up
some of mine have just music with them - this a good one
if she hears it a couple of times she is bound to ask what it is
