One day, Izzy is out exploring when she finds a strange rock on Swanage beach. No sooner has she started fiddling with it, she and Pipp suddenly find themselves on the other side of the world.

Whilst having to adapt to a new time zone and life on the water alongside a fleet of boats, they will also have to contend with challenging work conditions, a new world completely, and some old enemies thrown into the mix. Will all be ship shape, or will the Mane 6 and the Star Fleet be sleeping with the fishes?

Based on the Set your Sail miniseries of MLP G5 comics, and a formal crossover with Tugs, the sister series of Thomas and Friends. Written to mark the second anniversary of Thomas and Friends: a New Generation.
