Worse Things Happen at Sea

WORSE THINGS HAPPEN AT SEA

On your first journey you will find your ship in reasonably sound condition; the only small problem being a slighty leaky hull. Under your control, your waterproofed and capable old C-Droid helper grinds from compartment to compartment applying patches to the ever increasing number of leaks.
When you complete your journey the profits from selling your cargo will be decreased by the cost of pumping out the hull, the cost of replacing any spoilt cargo, and the cost of buying new C-Droids to replace the ones you've wiped out. The second journey sees you with fresh cargo, and a ship that not only leaks, but also suffers from a tendency to wander off course. Apart from patching the hull, therefore, your C-Droid will also have to return to the wheel occasionally to keep the old tub on course. Watch that course indicator!!
On the third journey there's even more to do.
