What do you do when you learn that a Category 4 tropical cyclone is headed directly for the set of islands where you are planning to do a 3-day sailing trip? If you are Lustin — and especially if you are Lustin after just spending three days on a heaving, tossing ocean — you aren’t all that eager to tempt your fate with the seasickness gods again. Nor are you especially excited about sailing around normally sun-soaked tropical islands in the pouring rain. So, you do what any rational person would do — you change the entire itinerary for the remainder of your time in Australia less than 12 hours before your next flight is supposed to take off.
