Interesting stuff this thread. Your old Wombat is more of the opinion that no matter what the adventure planned , the age difference is the problem and that only because I just know that the chattering of a 23 year old, the general immaturity and probably her taste in music would result in me jumping overboard. On the otherhand the mumbling of a 55 year old, my general curmudgeonly behaviour and my taste in music would probably cause the poor women to contemplate suicide herself.
To repeat myself, however, you have to worry about someone embarking on a three year voyage with no previous offshore experience.
