Step-by-step explanation:
Victor Frankenstein arrived on Walton's ship by sailing on small boat. After being thrown into a tumultuous sea and struggling against a powerful current, he managed to make it to Walton's ship, which was on an expedition in the Arctic. This event is similar to the experiences shared in the passages provided, where characters face challenging conditions at sea, demonstrating the power and unpredictability of oceanic forces.
