Based on the clues provided, we can deduce the following:

Mr. Jones hates flying, which means he did not take a plane.
Cindy had to rent her vehicle, which means she did not take a ship (since ships cannot be rented casually).
John gets seasick, which means he did not travel by ship.
Considering these facts and the options available (train, car, plane, ship), we can derive the following:

Mr. Jones must have travelled by train or car, but since Cindy had to rent her vehicle, we can deduce that she rented a car, hence Mr. Jones took the train.
Cindy rented a vehicle, which as deduced earlier, must have been a car.
John did not travel by ship due to his seasickness, and since the plane and car options are already taken, he must have travelled by train.
Rachel, as the last person, took the only remaining option, which is the ship.
So, to summarize:

Mr. Jones travelled by train.
Cindy travelled by car.
John travelled by train.
Rachel travelled by ship.
